In how many map squares did we spot less than 20 plant species
The number of spice plants spotted in the map are 3.
What is histogram?A histogram is a visual representation of statistical data that makes use of rectangles to illustrate the frequency of data items in a series of equal-sized numerical intervals. The independent variable is represented along the horizontal axis and the dependent variable is plotted along the vertical axis in the most popular type of histogram.
We need to spot less than 20 plant species.
From the given histogram,
Between the interval 0-9 there is 1 spice plant.
Between the interval 10-19 there is 2 spice plant.
So, total = 1+2=3
Therefore, the number of spice plants spotted in the map are 3.

Use the net to find the surface area of the rectangular prism.
Answer:
220
Step-by-step explanation:
The surface area is given by
SA = 2 ( lw+wh+lh) where l is length h is height and w is width
SA = 2(3*4 + 3*14+ 4*14)
= 2(12+42+56)
= 2(110)
= 220
The calculated surface area of the net is 208 square units
Finding the surface area of the net
From the question, we have the following parameters that can be used in our computation:
The net of the prism
The surface area of the net is then calculated as
Surface area = Area of big rectangle + 2 * Area of small rectangle
So, we have
Surface area = (14 + 3 + 14) * 4 + 2 * 3 * 14
Evaluate
Surface area = 208
Hence, the surface area of the net is 208 square units
A computer monitor has a rectangular viewing area of 135 square inches. The viewing area is 9 inches tall. What is the
width of the viewing area?
Answer: 15 inches wide
Step-by-step explanation:
to find the area of a rectangle you would multiply the height by the width so this would be the opposite because we have the area which is 135 in.² so we would divide 135 by 9 which would give us 15.
What is the area pf the parallelogram, with lengths as marked, shown above?
Answer:
40

Two angles are supplementary. The first angle is 8x degrees. The second angle is(4x+12). Determine the measure of each angle.
Answer:
The measure of the angles are 112 degrees and 68 degrees.
Step-by-step explanation:
Two angles are supplementary if they add up to 180 degrees.
The first angle is 8x degrees.
The second angle is (4x+12) degrees.
Therefore:
8x+4x+12=180 degrees
12x+12=180
12x=180-12
12x=168
Divide both sides by 12
x=14 degrees
Substituting x in the given angles:
8x =8*14=112 degrees
4x+12=4(14)+12=68 degrees
Therefore, the measure of the angles are 112 degrees and 68 degrees.

If 45% of an item is $27.00 what is the original price?
Answer:
It would be $12.15.
Step-by-step explanation:
You would multiply 45% of 27.
45 * 27 = $12.15
Answer:
$12.15 is 45% of $27, so if the item was marked up, you add 12.15 and 27, and if it was marked down, you do 27 - 12.15
Step-by-step explanation:
a = p*w
a = .45*27
a = 12.15

if rectangle a and rectangle b have a ratio of similarity of 5:4, what is the area of rectangle B if the area of the rectangle A is 24 square units
Answer:
the answer is 30 this is because if you rectangle b is 24 then rectangle a is 30 like if you simplify 30:25 if you divide it by 6 it will give 5:4
Step-by-step explanation:
Final answer:
The area of rectangle B is approximately 15.36 square units.
Explanation:
To find the area of rectangle B, we can use the ratio of similarity.
The ratio of similarity between rectangle A and rectangle B is 5:4.
Since the area of rectangle A is 24 square units, we can set up the equation:
(area of B) / (area of A) = (side length of B)² / (side length of A)².
Substituting the values, we get
(area of B) / 24 = (4/5)².
Solving for the area of B, we have
(area of B) = 24 * (4/5)²
= 24 * 16/25
= 384/25
= 15.36 square units.

Step-by-step explanation:
The amount of icing on a Cuppie Cake large cupcake follows a Normal distribution, with a
mean of 2 ounces and a standard deviation of 0.3 ounce. A random sample of 16 cupcakes
is selected every day and measured. What is the probability the mean weight will exceed
2.1 ounces? (2 points)
O 0.9088
0.3694
0.0912
0.6306
0.075
The probability of mean weight will exceed 2.1 ounces is 0.0912.
To solve this problem, we need to calculate the probability that the mean weight of the icing on a sample of 16 cupcakes exceeds 2.1 ounces, given that the distribution of the icing weights is normal with a mean of 2 ounces and a standard deviation of 0.3 ounce.
First, we need to find the standard error of the mean (SEM) for the sample of 16 cupcakes. The SEM is calculated by dividing the population standard deviation by the square root of the sample size:
[tex]\[ SEM = \frac{\sigma}{\sqrt{n}} = \frac{0.3}{\sqrt{16}} = \frac{0.3}{4} = 0.075 \][/tex]
Now, we need to find the z-score for the value of 2.1 ounces. The z-score is calculated by subtracting the population mean from the value in question and then dividing by the SEM:
[tex]\[ z = \frac{\bar{x} - \mu}{SEM} = \frac{2.1 - 2}{0.075} = \frac{0.1}{0.075} = \frac{4}{3} \approx 1.3333 \][/tex]
Next, we look up this z-score in the standard normal distribution table or use a calculator to find the probability of a z-score being less than 1.3333. This gives us the probability that the mean weight of the icing is less than or equal to 2.1 ounces.
[tex]\[ P(Z < 1.3333) \approx 0.9088 \][/tex]
However, we want the probability that the mean weight exceeds 2.1 ounces, so we need to subtract this value from 1 (the total probability):
[tex]\[ P(\bar{x} > 2.1) = 1 - P(Z < 1.3333) = 1 - 0.9088 = 0.0912 \][/tex]
Therefore, the probability that the mean weight of the icing on a sample of 16 cupcakes will exceed 2.1 ounces is 0.0912.

Which relationship in the triangle must be true?
sin(B) = sin(A)
sin(B) = cos(90 -B)
cos(B) = sin(180 - B)
cos(B) = cos(A)
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)

Solving systems of equations algebraically.
y = 4x - 9
y= x - 3
And SHOW YOUR WORK PLEASE!!!!
Answer:
x = 2
y = -1
Step-by-step explanation:
Since it gives you the value of y already, just plug that into the equation, like so:
y = 4x - 9
x - 3 = 4x - 9
Subtract the x from both sides:
x - 3 = 4x - 9
-x - x
__________
-3 = 3x - 9
Then, add 9 to both sides:
-3 = 3x - 9
+9 + 9
________
6 = 3x
Divide both sides by 3:
2 = x
Now plug in x for y:
y = x - 3
y = 2 - 3
y = -1

What is an equation?An equation is an expression that is used to show the relationship between two or more variables and numbers.
Given that:
I(dB) = 10log(I/I₀)
Where I is the intensity of sound in w/m², I₀ = 10⁻¹²
Given that I = 10³², hence:
I(dB) = 10log(10³²/10⁻¹²) = 440 dB
The intensity of a sound of 10³² w/m² is 440 decibels.

Susan invested some money at 6% annual interest and 800 dollars at 7%. The money earned 128 dollars interest in a year. How much was invested at 6%?
Answer:
Susan invested some money (M) at 6% annual interest and 800 dollars at 7%. The money earned 128 dollars interest in a year. Then we have:
M x 6/100 + 800 x 7/100 = 128
=> M*0.06 = 128 - 800*0.07 = 128 - 56 = 72
=> M = 72/0.06 = 1200 dollar
