Which expression is equivalent to
- 5/3?
Answer:
The first one! :)
Step-by-step explanation:
At the bottom of each question for example the first on it has 1 at the top then at the bottom it says 5/3 with a x.So if it does not say 5/3 it can be excluded.So it says only one 5/3.So one 5/3 is the exact same as 5/3!
And for the last one says -5/3.:)
And no im not saying 1 5/3 :(

What are Equivalent Fractions?Equivalent fractions are fractions that represent the same value, even though they look different. A fraction has two parts. The number on the top of the line is called the numerator which tells how many equal parts of the whole or collection are taken. The number below the line is called the denominator and it shows the total number of equal parts the whole is divided into or the total number of equal parts which are there in a collection.To learn more about equivalent refer to:

What does statement that is not correct to use probability to describe an event.
A) the probability of seeing the Stars night is 0.70
B) the probability of going back to time is 0
C) The probability of having leftovers for dinner tonight is 35 percent
D) The probability of finding my keys is - 1/5
The incorrect statement is option D) The probability of finding my keys is - 1/5, as probabilities cannot be negative. Probabilities range between 0 and 1, and the calculation for combined probability of independent events involves multiplication, not addition.
The statement that is not correct to use probability to describe is option D) The probability of finding my keys is - 1/5. Probabilities range from 0 to 1 (or 0% to 100%), where 0 indicates impossibility and 1 indicates certainty. A negative probability does not make sense within this framework, so option D reflects a misunderstanding of how probabilities are represented.
The correct way to calculate the combined probability of two independent events is to multiply their individual probabilities. For example, to find P(A AND B) when dealing with independent events, you would calculate P(A) * P(B). Therefore, if P(A) = .2 and P(B) = .3, the correct answer for P(A AND B) would be .06, which corresponds to option D in the exercise provided.
It is also important to clarify misconceptions such as adding probabilities of non-mutually exclusive events. For instance, the fallacy that if there is a 60 percent chance of rain on one day and a 70 percent chance on another, then there is a 130 percent chance of rain over the weekend.
This is incorrect because probabilities cannot exceed 100%. Instead, you would evaluate the chances of rain differently depending on the independence or interdependence of the weather on those days.
Consider the exponential function f(x) = 1 (154). What is the value of the growth factor of the function?
The value of the growth factor of the function is 15. To add to your answer, exponential growth happens when the rate of the number of the function corresponds with the present value of the function. This then lets its increase together with time be called an exponential function.
Answer:
15.
Step-by-step explanation:
f(x) = a b^x
The growth factor is b - in this case 15.

Answer:
the total value of the liquid in the container is $29.4
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cone
The volume of a cone is expressed as
V=1/3(πr²h)
Given data
Height h= 9 inches
Radius r= diameter/2= 2.5/2= 1.25in
Substituting we have
V= 1/3(3.14)*(1.25)²*9
V= 1/3*(3.14)*14.06
V= 44.156/3
V= 14.7in³
The volume of the cone is 14.7in³
Hence If 1 in³ of liquid costs $2
14.7in³ will cost $x
x= 14.7*2

The equation y= ax describes the graph of a line. If the value of a is positive,
What direction does the line go?
Answer:
Step-by-step explanation:
If the value a is positive in the linear equation y = a x ( for example: y = 2 x ) then the line ( from the left to the right ) must go up and to the right. It also passes through the origin ( 0, 0 ). For x = 1: y = 2 * 1 = 2, so that point is ( 1, 2 ), x2 > x1, and y2 > y1.Answer:A. goes up and to the right.
Final answer:
The line described by the equation y = ax slopes upward to the right when the value of a is positive, illustrating a positive relationship between x and y.
Explanation:
The equation y = ax describes a linear relationship between x and y. When the value of a is positive, the line slopes upward to the right on a graph. This behavior is because a positive slope indicates that as the x-value increases, the y-value also increases, leading to an upward trajectory on the graph.
The direction in which the line moves across the graph depends solely on the sign of a, where a positive a signifies an upward slope and a negative a results in a downward slope. Specifically, for a positive a, for every unit increase in x, there is a proportional increase in y, making the graph rise from left to right.
Write an equation to represent the following statement.
10 less than j is 35.
_______
Solve for j.
j =_____
Answer:
j - 10 = 35
j = 45
Step-by-step explanation:
When it says, "less than" it means subtracting. So 10 less than j is (j - 10)
The part where is says "is" means it is equal to.
So the equation would be = (j - 10) = 35
Answer:
Equation: (j - 10) = 35
j = 45
Step-by-step explanation: Lets translate 10 less than j:
Less than means 10 is being subtracted from j.
So we can write 10 less than j as j - 10.
The word is means equal.
So, we can write is 35 as = 35.
Now lets write the whole equation toghter.
j - 10 = 35
We can also write this as 35 = j - 10.
Now we can solve for j.
Add 10 to both sides of the equation to get j by itself.
j - 10 + 10 = 35 + 10
J=45
The following equation matches this situation:
j - 10 = 35
j = 45

A senator wishes to estimate the proportion of United States voters who favor
abolishing the Electoral College. How large a sample is needed in order to be 90%
confident that the sample proportion will not differ from the true proportion by more
than 3%?
Answer:
[tex]n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.64})^2}=747.11[/tex]
And rounded up we have that n=748
Step-by-step explanation:
The confidence level is 90% and the significance level would be [tex]\alpha=1-0.9=0.1[/tex] and [tex]\alpha/2 =0.05[/tex] and the critical value for this case is:
[tex] z_{\alpha/2}= 1.64[/tex]
The margin of error for the proportion interval is given by this formula:
[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex] (a)
And on this case we want a margin of error of [tex]ME =\pm 0.03[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:
[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex] (b)
Since we don't hace any prior info for the population proportion we can use [tex]\hat p =0.5[/tex]. And replacing into equation (b) the values from part a we got:
[tex]n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.64})^2}=747.11[/tex]
And rounded up we have that n=748
Using the sample size formula, the required number of sample is 752.
Using the confidence interval relation :
[tex] n = \frac{pq}{(\frac{E}{Z_{crit}})^{2}} [/tex] p =sample proportion = 0.5 q = 1 - p = 1 - 0.5 = 0.5 Zcrit at 90% = 1.645 E = Error Margin = 3% = 0.03Substituting the values into the equation :
n = [tex] \frac{0.5 \times 0.5}{(\frac{0.03}{1.645})^{2} }[/tex]
[tex] n = \frac{0.25}{0.0003325}[/tex]
[tex] n = 751.67[/tex]
Therefore, the required number of sample is 752.

Girls in science class account for one-third of the total number of students in their 3rd period class. 3 girls are absent today. Find the total number of students in the class if four girls attended class today.
Answer:
See Explanation
Step-by-step explanation:
The question isn't clear enough. However, I'll solve for the total number of students in science class and I'll.also solve for the total number of students present in class.
Given
Proportion of girls = ⅓
Number of girls absent = 3
Number of girls present = 4
Required
Find the total number of students
If 3 girls were absent and 4 were present, then there are total of 7 girls in science class.
Let the number of students in the class be represented by y.
⅓ of the total number of students are girls;
This means
⅓ of y = 7
⅓ * y = 7
Multiply both sides by 3
3 * ⅓ * y = 3 * 7
y = 3 * 7
y = 21.
Hence, the total number of students in science class is 21
Recall that 3 girls are absent;
This means that 21 - 3 are presently in the class.
21 - 3 = 18.
Hence, 18 students are presently in class.

Julius plants 25 trees in the section of the orchard called the South Hill region that measures 450 feet by 24 feet. Approximately how many trees does Julius plant in the orchard in all? (1 = 43,560 ).
A. 909
B. 1,151
C. 1,513
D. 1,746
Answer:
C
Step-by-step explanation:
Area of known planted trees: 450ft x 24ft = 10800 sq ft
total area of orchard: 43560 sq ft. x 15 acres = 653400 sq ft
653400 / 10800 = 60.5 "duplicated known areas"
25 trees in each "known area"
60.5 x 25 = 1512.5 trees

2. Substitute the value for y into the second equation: 7x + 2(3 − 3x) = 1
3. Solve for x: x =
Answer:
(-5, 18)
Step-by-step explanation:
7x + 2(3 − 3x) = 1 simplifies to
7x + 6 - 6x = 1, which, in turn, simplifies to:
x = -5
Using y = 3 - 3x (see Step 1), we find that y = 3 - 3(-5) = 3 + 15 = 18.
Thus, the solution is (-5, 18).

Are the events independent or dependent?
What is the probability?
Answer:
i say dependent. i may be wrong
7/26
Step-by-step explanation:
6/13 times 7/12 which is 42/156 which is 14/52 which is also 7/26
Final answer:
The scenario presents dependent events with the probability of selecting a boy first and then a girl being 7/26.
Explanation:
The events described in the scenario are dependent because the outcome of the first trial (selecting a student) affects the outcome of the second trial (selecting another student). In this situation, for the first student selected to be a boy, the probability is 6/13 (as there are six boys and seven girls, totaling 13 students). Once the first boy is selected and not replaced, the probability that the second student chosen is a girl is 7/12, because only 12 students remain and 7 of them are girls.
Therefore, the probability of first drawing a boy and then a girl, in two successive trials without replacement, is the product of the two individual probabilities: (6/13) * (7/12). This equals 42/156= 0.269 or simplified to 7/26.

Consider a single spin of the spinner. Which events are mutually exclusive? Choose all that apply. a)landing on a shaded sector and landing on a number greater than 3
b)landing on a shaded sector and landing on a 3
c)landing on a shaded sector and landing on an even number
d)landing on an unshaded sector and landing on a number less than 2
e)landing on an unshaded portion and landing on an odd number
Answer: the correct options are b and d.
Step-by-step explanation:
Let us first define what mutually exclusive events are. If two events are mutually exclusive, it means that they cannot happen at the same time. For example, getting a head and a tail at the same time are mutually exclusive.
Considering a single spin of the spinner, the events that are mutually exclusive are
b)landing on a shaded sector and landing on a 3. This is because 3 is unshaded. You can either land on 3 or an unshaded sector at a time
d)landing on an unshaded sector and landing on a number less than 2. This is because the numbers in the unshaded sectors are greater than 2.
