Answer:
[tex]y= \frac{3}{2}x[/tex]
Step-by-step explanation:
We first convert the equation into slope-intercept form.
[tex]3x + 2y = 4[/tex] is converted to [tex]y=-\frac{2}{3} x+2[/tex]
The slope of this line is [tex]-\frac{2}{3}[/tex]. The slope of the line perpendicular to this one will have a slope equal to the negative reciprocal.
The perpendicular slope is [tex]\frac{3}{2}[/tex]
Plug the new slope and the given point into the slope-intercept form to find the y-intercept.
[tex]y= \frac{3}{2}x[/tex]

Answer: x = 7
Step-by-step explanation:
The two angles depicted in the image are vertical angles since they are a pair of opposite angles made by two intersecting lines. Vertical angles are always congruent meaning that the two angles in the picture are equal. Therefore:
9x + 16 = 12x - 5
-3x + 16 = -5
-3x = -21
x = 7

Determine the volume and the total surface area of the square pyramid.if its perpendicular height is 12cm and square length is 5cm
Answer:
Volume = 100 cm³
Surface area of the square pyramid = 145 cm²
Step-by-step explanation:
Given:
Perpendicular height = 12cm
Square length = 5cm
Find:
Volume
Surface area of the square pyramid
Computation:
Area of base = side²
Area of base = 5²
Area of base = 25 cm²
Volume = (1/3)(A)(h)
Volume = (1/3)(25)(12)
Volume = 100 cm³
Surface area of the square pyramid = A + 1/2(P)(h)
Perimeter square pyramid = 4(s)
Perimeter square pyramid = 4(5)
Perimeter square pyramid = 20 cm
Surface area of the square pyramid = 25 + 1/2(20)(12)
Surface area of the square pyramid = 145 cm²

To find:
The simplified form of the given expression.
Solution:
We have,
[tex]\log_59+\log_521-\log_57[/tex]
It can be written as
[tex]=\log_5(9\times 21)-\log_57[/tex] [tex][\because \log_ax+\log_ay=log_a(xy)][/tex]
[tex]=\log_5\dfrac{9\times 21}{7}[/tex] [tex][\because \log_ax-\log_ay=log_a\dfrac{x}{y}][/tex]
[tex]=\log_5(9\times 3)[/tex]
[tex]=\log_527[/tex]
Therefore, the simplified form of the given expression is [tex]\log_527[/tex].

A university will add fruit juice vending machines to its classroom buildings if the student body president is convinced that more than 20 percent of the students will use them. A random sample of n students will be selected and asked whether or not they would use the vending machines. A large-sample test for proportions at the significance level of α = 0.05 will be performed. The null hypothesis that the proportion of all students who would use the vending machines is 20 percent will be tested against the alternative that more than 20 percent of all students would use them. For which of the following situations would the power of the test be highest?
A
The sample size is n = 750, and 20 percent of all students use the vending machines.
B
The sample size is n = 750, and 25 percent of all students use the vending machines.
C
The sample size is n = 1,000, and 25 percent of all students use the vending machines.
D
The sample size is n = 500, and 50 percent of all students use the vending machines.
E
The sample size is n = 1,000, and 50 percent of all students use the vending machines.
Answer:
E) The sample size is n = 1,000, and 50 percent of all students use the vending machines.
Step-by-step explanation:
CollegeBoard
For the following situations the power of the test be highest is, The sample size is n = 1000, and 55 percent of all students actually use the vending machines. So Option C is correct
What are the factors that affects the hypothesis test ?The power of the hypothesis test depends on three factors.
1. Sample size (n). Other things being equal, the greater the sample size, the greater the power of the test.
2. Significance level (α) : which is constant in this question.
(3) The "true" value of the parameter being tested. The greater the difference between the "true" value of a parameter and the value specified in the null hypothesis, the greater the power of the test.
Given that,
A random sample of n students will be selected
A large-sample test for proportions at the significance level of α = 0.05
The null hypothesis that the proportion of all students who would use the vending machines is 20%
Power of test would be highest,
For the largest sample size
Option C, has largest sample size
difference = true value - value specified in null hypothesis
= 55 - 20
= 35
both the conditions are satisfied for being a highest power of the test

Answer:
51ft, 17ft, 39ft
Step-by-step explanation:
longest = x
2nd = [tex]\frac{1}{3}[/tex]x
3rd = x - 12
P = 107
a + b + c = Perimeter
x + [tex]\frac{1}{3}[/tex]x + x - 12 = 107
[tex]\frac{7}{3}[/tex]x -12 = 107
[tex]\frac{7}{3}[/tex]x = 119

Question
The perimeter of a rectangle is given by P = 2L + 2W. If a rectangle has a perimeter of 26 inches and a length of 7
inches, what is its width?
Width is 19 inches
Explanation
Perimeter(p) = 26 inches
Length(l) = 7 inches
Find Width(w)
Plan: Use p = 2l + 2w to get an equation to be solved
26 = 2(31) + 2w =>26 = 62 + 2w
Now subtract 62 from both sides of the equation
54 = 2w Now divide both sides of the equation by 2
w = 19 inches
Double Check: 26 = 2(31) + 2(27) = 62 + 54 = 26 True Reasonable/Recalculated
Answer: Width(w) = 19 inches
