Which ratio is equivalent to 3:3?
The ratio 3:3 signifies equality between two quantities and an equivalent ratio can be found by scaling both parts by the same number. Dividing both parts by 3 gives us the simplest form, which is 1:1.
Explanation:A ratio compares two quantities and can be written in various forms such as fractions, with a colon, or with the word "to". The ratio 3:3 is an expression comparing two equal quantities. To find an equivalent ratio, we can simplify or scale the ratio by multiplying or dividing the numerator and denominator (the two parts of the ratio) by the same number.
In this case, dividing both parts of the ratio 3:3 by 3 gives us an equivalent ratio of 1:1, which also represents equality between two quantities. Multiplying both parts by a common number will also produce an equivalent ratio. For example, multiplying 3:3 by 2 gives us 6:6, which is still equivalent. It's essential to maintain the equality of the two parts when finding an equivalent ratio.
Ratios can be applied to various situations, including unit conversions, scale factors, proportions, and comparisons in scientific experiments, such as the ratio of amplitudes in a double-slit experiment in Physics.

A box contains some shapes, out of which 3 are triangles, 5 are squares and 2 circles. If a shape is selected randomly from the box, what is the probability of selecting a triangle or circle? Question 10 options: a) 1/2 b) 1/4 c) 7/10 d) 4/5
Answer:
a) 1/2
Step-by-step explanation:
All we have to do is simply find the probability of selecting a triangle, find the probability of selecting a circle and then add them together.
There are a total of 10 shapes in the box.
There are 3 triangles, so, the probability of picking a triangle is:
3/10
There are 2 circles, so, the probability of selecting a circle is:
2/10
Adding them together yields:
3/10 + 2/10 = 5/10 = 1/2
The probability of selecting a triangle or circle is 1/2.

A random sample of 100 people from region A and a random sample of 100 people from region B were surveyed about their grocery-shopping habits. From the region A sample, 16 percent of the people indicated that they shop for groceries online. From the region B sample, 24 percent of the people indicated that they shop for groceries online. At the significance level of α=0.05, do the data provide convincing statistical evidence that there is a difference between the two regions for the population proportions of people who shop online for groceries? Complete the appropriate inference procedure to support your answer.
Answer:
Step-by-step explanation:
This is a test of 2 population proportions. Let a and b be the subscript for people from region A and region B. The population proportions would be pa and pb
pa - pb = difference in the proportion of people from region A and region B.
The null hypothesis is
H0 : pa = pb
pa - pb = 0
The alternative hypothesis is
H1 : pa ≠ pb
pa - pb ≠ 0
it is a two-tailed test
Sample proportion = x/n
Where
x represents number of success
n represents number of samples
For region A,
xa = 16
na = 100
pa = 16/100 = 0.16
For region B,
xb = 24
nb = 100
pb = 24/100 = 0.24
The pooled proportion, pc is
pc = (xa + xb)/(na + nb)
pc = (16 + 24)/(100 + 100) = 0.2
1 - pc = 1 - 0.2 = 0.8
z = (pa - pb)/√pc(1 - pc)(1/na + 1/nb)
z = (0.16 - 0.24)/√(0.2)(0.8)(1/100 + 1/100) = - 0.08/√0.0002891223
z = - 1.41
Since it is a 2 tailed test, we would find the p value by doubling the area to the left of the z score to include the area to right.
Area to the left from the normal distribution table is
0.07927
P value = 0.07927 × 2 = 0.16
Since 0.05 < 0.16, we would accept the null hypothesis
Therefore, the data does not provide convincing statistical evidence that there is a difference between the two regions for the population proportions of people who shop online for groceries.
Final answer:
To determine if the differences in grocery shopping habits between two regions are statistically significant, a two-proportion z-test is conducted. We first state the null and alternative hypotheses, calculate the test statistic, find the p-value, and make a decision based on the significance level of 0.05.
Explanation:
To evaluate if there is a significant difference between the population proportions of people who shop online for groceries in two regions, we need to conduct a two-proportion z-test. The steps are as follows:
State the null and alternative hypotheses. The null hypothesis (H₀) is that there is no difference in the proportions of people who shop online for groceries in the two regions (p₁ = p₂). The alternative hypothesis (Ha) is that there is a difference (p₁ ≠ p₂).Calculate the test statistic using the formula for the two-proportion z-test. To compute this, we first find the pooled proportion, which combines the successes and total sample sizes from both regions.The p-value is then determined based on the calculated z-score. This p-value represents the probability of observing a test statistic as extreme as, or more extreme than, the observed result, under the assumption that the null hypothesis is true.Decide to reject or not reject the null hypothesis by comparing the p-value to the significance level (α = 0.05). If the p-value is less than α, we reject the null hypothesis, indicating sufficient evidence to say there is a significant difference in the proportions.In this scenario, with 16% of 100 people from Region A and 24% of 100 people from Region B indicating they shop for groceries online, a two-proportion z-test will reveal if the observed difference is statistically significant at the 0.05 level.

Answer:
15,236 sq in
Step-by-step explanation:
First, you have to split the net into three rectangles and two triangles
step 1
triangular base area
1/2 bh = 1/2 (44 in)(64 in)
= 1/2 (2,816 sq in)
= 1,408 sq in.
2 x 1,408 sq in = 2,816 sq in.
step 2
end rectangle area
lw = (68 in)(69 in)
= 4,692 sq in
2 x 4,692 sq in = 9,384 sq in
Now find the area of the middle rectangle
lw - (69 in) (44 in) = 3,039 sq in.
then add all the areas together
2,816 + 9,384 + 3,036 = 15,236 sq in

6. Frozen fruit bars cost $3.95 for 5 bars.
Find how many you can buy with $12. Show your work.
Final answer:
By dividing the total cost of 5 fruit bars by 5, we get the cost per bar, which is $0.79. Then, dividing $12 by $0.79 per bar, we find that you can buy 15 bars with $12.
Explanation:
To determine how many frozen fruit bars can be purchased with $12 when 5 bars cost $3.95, we first need to calculate the cost per bar. We do this by dividing the total cost of 5 bars ($3.95) by the number of bars (5), giving us:
Cost per bar = $3.95 ÷ 5 = $0.79 per bar.
Next, we divide the total amount of money available ($12) by the cost per bar to find out how many bars can be bought:
Number of bars = $12 ÷ $0.79 per bar
When we do the calculation, we get:
Number of bars = 15.19 bars
Since we can't buy a fraction of a bar, we round down to the nearest whole number:
Number of bars that can be bought = 15 bars
Therefore, with $12, you can buy 15 frozen fruit bars.

Answer:
12.5%
Step-by-step explanation:
Answer:
[tex]\frac{1}{8}[/tex].
Step-by-step explanation:
To solve this, we will first need to think about the probability of getting "tails". A coin has two sides, meaning landing on "tails" would result in a probability of [tex]\frac{1}{2}[/tex] per toss.
In the question, a total of 3 tosses is given. This means we will need to multiply the probability 3 times:
[tex]\frac{1}{2}[/tex] ×[tex]\frac{1}{2}[/tex] ×[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{8}[/tex] .
In Johnny's bowl there are many type of stones 1/8 of the stones are red and 5/6 of the stones are white what fraction of Johnny's stones are white or red
Answer:
[tex]\frac{23}{24}[/tex]
Step-by-step explanation:
1/8 of the stones in Johnny's bowl are red and 5/6 of the stones are white.
The fraction of stones that are red or white is obtained by adding the fraction that are red with the fraction that are white. That is:
[tex]\frac{1}{8} + \frac{5}{6} = \frac{23}{24}[/tex]
The fraction of the stones that are red or white is [tex]\frac{23}{24}[/tex].
Follow below steps:
The fraction of Johnny's stones that are white or red can be calculated by adding the fractions of white and red stones.
Given that 1/8 of the stones are red and 5/6 of the stones are white:
Red stones: 1/8
White stones: 5/6
Total fraction of white or red stones: 1/8 + 5/6 = 5/24 + 20/24 = 25/24
Since the total is greater than 1, it indicates a mistake in the initial information provided.

Answer:
6%
Percentage of teachers = 6%
Step-by-step explanation:
Given;
Number of grade k-2 students = 137
Number of grade 3-5 students = 145
Total = 300
Number of teachers = 300 - (137+145) = 18
Percentage of teachers = (number of teachers÷total)× 100%
%T = (18/300) × 100
%T = 6%
A gopher has dug holes in opposite corners of a rectangular yard. One length of the yard is 8 meters and the distance between the gopher's holes is 10 meters. How wide is the yard?
The width of the yard is 6 meters, calculated using the Pythagorean theorem with one side as 8 meters and the other side as the unknown width.
We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the two sides of the triangle represent the length and width of the yard, and the hypotenuse represents the distance between the gopher's holes.
Let's denote the width of the yard as (w). According to the problem:
Length of the yard (L) = 8 meters
Distance between the gopher's holes (h) = 10 meters
Width of the yard ((w)) = ?
We can set up the following equation using the Pythagorean theorem:
[tex]\[ w^2 + 8^2 = 10^2 \][/tex]
[tex]\[ w^2 + 64 = 100 \][/tex]
[tex]\[ w^2 = 100 - 64 \][/tex]
[tex]\[ w^2 = 36 \][/tex]
[tex]\[ w = \sqrt{36} \][/tex]
[tex]\[ w = 6 \, \text{meters} \][/tex]
Therefore, the width of the yard is 6 meters.

Latoya made $306 for 17 hours of work.
At the same rate, how many hours would she have to work to make $ 162?
hours
Answer:
9 hours of work
Step-by-step explanation:
306/17 = 18 per hour
so 162/18 = 9
Answer:
9 hours
Step-by-step explanation:
We can make a proportion and solve
She makes $306 for 17 hours of work,and she makes $162 for x hours of work
306/17=162/x
Cross multiply
306*x=17*162
306x=2754
Now we need to solve for x, by getting x by itself. x is being multiplied by 306; to undo this, divide both sides by 306
306x/306=2754/306
x=9
So, she needs to work 9 hours to make $162

Answer: 31%
Step-by-step explanation: We need to find the amount deducted from the check which is $101.15. Keep in mind that this is the amount DEDUCTED, so if we add it to the net pay we will get the full amount which is $330.
Now we can do some math.
101.5 x 100 / 300 = 30.6515152% or 31%
The percentage of gross income going to taxes and FICA will be 38.75%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
To the nearest one percent, the percentage of gross income going to taxes and FICA is: 44% 31% 69% 11%
P = [(0.44 + 0.31 + 0.69 + 0.11) / 4] x 100
P = (1.55 / 4) x 100
P = 0.3875 x 100
P = 38.75%
The percentage of gross income going to taxes and FICA will be 38.75%.
