Answer:
For part A, you could decompse the figure into a rectangle and two triangles.
for Part B, its the first one.
Step-by-step explanation:
If you split up the figure into two parts then you will get 2 triangles and a rectangle. The area of 1 triangle is
A=1/2xbh
but there are two triangles so it would be 2(1/2x bh).
you can then multiply tht by the areaof the rectangle and get
2(1/2x12*5)+(16*12)

Scores on an IQ test are normally distributed. A sample of 25 IQ scores had standard deviation of 8. The developer of the test claims that the population standard deviation of 15. Do these data provide sufficient evidence to significance? Use =0.05α=0.05 . Test by using a confidence interval. Show step1-step3.
Answers
Answer:
Yes, the data provides sufficient evidence at 0.05 level of significance
Step-by-step explanation:
n = 25
s = 8
σ = 15
χ² = (n - 1)s² / σ²
χ² = (25 - 1)*8² / 15²
χ² = (24 * 64) / 225
χ² = 6.827
The critical value at 0.05 ; df = 25 - 1 = 24
12.4012 and 39.3641
Reject H0 if χ² < 12.4012 or if χ² > 39.3641
Since,
χ² < 12.4012 ; We reject H0 ;

what is the volume of the figure shown? explain how you solved the problem.
Answers
Answer:
840
Step-by-step explanation:
To find the volume of a rectangular prism, you do length * height * width
The height for both of the figures are 6
The length is 10 for both of the figure
The width for the bottom figure is 9 and for the top, the width is 5
First solve the top one
5 * 6 = 30
30 * 10 = 300
So the volume for the top figure is 300
The solve the bottom figure with the same formula
6 * 9 = 54
54 * 10 = 540
So the volume for the bottom figure is 540
Finally add them together
300 + 540 = 840
Your answer is 840

what is the equation of this line
a. y = -3/2x+9
b. y = -2/3x+18
c. y = 2/3x+6
d. y = 3/2x+6
Answers
Answer:
A. y = -3/2x + 9
Step-by-step explanation:
In slope intercept form (y = mx + b), b represents the y-intercept. Therefore, simply look on the graph where the line intersects with the y-axis. In this case, that is all that was needed since we can clearly see that equation A is the only one with a y-intercept of 9.
Answer:
a
Step-by-step explanation:
any two points on the line are
(0,9 ) and (4,3)
slope=(3-9)/(4-0)=-6/4=-3/2
y intercept is 9
so eq. of line is y=-3/2x+9
A student would like to estimate the proportion of students at his school who have lunch during period 4. To do so,
he selects a random sample of 40 students and finds that 30% of them have period 4 lunch. Later, he goes to the
guidance office and finds that of the 380 students at this school, 25% of them have period 4 lunch. Which of the
following properly describes the number, 25%?
sample
statistic
population
parameter
Yeah
Answers
Answer:
D
As we are getting the 25% from the whole population of 380 students, therefore this is a population proportion which is a parameter. Note that we get parameter from population and statistic from the sample.
Step-by-step explanation:
The property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.
What are population and sample?It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
We have:
Number of samples = 40
30% of them have period 4 lunch.
Total population = 380
25% of them have period 4 lunch.
Because we're collecting 25% from a population of 380 students, this is a population proportion that may be used as a metric.
We collect parameters from the population and statistics from the sample.
Thus, the property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

Okay so first subtract 8 on both sides...
5x= 25
Now we need to divide on both sides!
That equals...
x=5

Substitution
Substitute in y [1st Equation]: -10x = -7x + 6[Addition Property of Equality] Add 7x on both sides: -3x = 6[Division Property of Equality] Divide -3 on both sides: x = -2Step 3: Solve for y

Maria plans to use fencing to build an enclosure or enclosures for her two horses. A single enclosure would be square shaped and require an area of 2,025 ft2. Two individual adjacent enclosures would be rectangular, with dimensions 20 ft by 40 ft with a 40 ft divider between the two enclosures. A square and a rectangle are shown. The square has an area of 2,025 feet squared. The rectangle is comprised of 2 rectangles that are 20 by 40 feet long. Which statement explains the design Maria should choose to minimize her costs
Answers
Answer:
A. The singular enclosure would minimize cost because it requires 180 feet of fencing.
Step-by-step explanation:
Given
Single enclosure
[tex]Area = 2025ft^2[/tex] --- of square
Two adjacent enclosures
[tex]Dimension= 20ft\ by\ 40ft[/tex] ---- both rectangles
[tex]Divider = 40ft[/tex]
Required
Determine the true statement to minimize cost
Start by calculating the perimeter of the single enclosure.
Let
[tex]l \to[/tex] length of the enclosure (square shape)
So:
[tex]Area = l^2[/tex]
[tex]2025 = l^2[/tex]
Rewrite as:
[tex]l^2 = 2025[/tex]
Take square roots
[tex]l = 45[/tex]
The perimeter (P) is then calculated as:
[tex]P = 4l[/tex]
[tex]P = 4 * 45[/tex]
[tex]P_1 = 180ft[/tex]
Next, the perimeter of the two enclosures.
Let
[tex]l \to[/tex] length of the enclosure
[tex]w \to[/tex] width of the enclosure
[tex]l = 20[/tex]
[tex]w =40[/tex]
The perimeter of 1 enclosure is:
[tex]P = 2(l + w)[/tex]
[tex]P = 2(20 + 40)[/tex]
[tex]P = 2*60[/tex]
[tex]P = 120[/tex]
For 2 enclosures
[tex]P_2 =2 * P[/tex]
[tex]P_2 =2 * 120[/tex]
[tex]P_2 =240[/tex]
Remove the length of the divider
[tex]P_2 = 240 - 40[/tex]
[tex]P_2 = 200ft[/tex]
By comparison;
[tex]P_1 < P_2[/tex]
i.e.
[tex]180ft < 200ft[/tex]
Hence, the singular enclosure will minimize costs

Answers
Answer:
F(2x+3) = 12/(2x+3) +1/2
Step-by-step explanation:
Put the argument of the function where the variable is. You can simplify if you want, but the original function definition is not simplified, so we assume it is not required.
F(x) = 12/x + 1/2
Put (2x+3) where x is:
F(2x+3) = 12/(2x+3) + 1/2
12/k+1/2
24/a+1/2
12/x-1+1/2
12/2x+3+1/2
