Answer:
Angles that form a linear pair always =180
so set up an equation 4x+4+4x-32=180
now solve for x
Step-by-step explanation:
Two angles whose sum is 180° are called supplementary angles. The value of x is 26.
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
The two given angles are supplementary to each other, therefore, the sum can be written as,
4x+4+(4x - 32) = 180
4x+4+4x-32=180
8x=180+32-4
8x=208
x = 26
Hence, the value of x is 26.

MODELING REAL LIFE A survey asked students to choose their favorite social media website Social Media Website Number of Students Website A 35 Website B 13 Website C 22 Website D 10 a. What fraction of the students chose Website A?
__ chose Website A.
b. What percent of the students chose Website C?
__ % chose Website
Answer: For A = 35/80 or 43.75% C = 22/80 or 27.5 %
Step-by-step explanation:
I’m not sure if this is right but since 35 students choose A that would be the numerator and the denominator is how many people voted and when you add all 4 options you get 80 so it would be 35/80 and same apply to C which would be 22/80

A sample of 300 subscribers to a particular magazine is selected from a population frame of 9,000 subscribers. If, upon examining the data, it is determined that no subscriber had been selected in the sample more than once:________.
A. the sample could not have been random
B. the sample may have been selected without replacement or with replacement
C. the sample had to have been selected without replacement
D. the sample had to have been selected with replacement
Answer:
C
Step-by-step explanation:
It is determined that no subscriber had been selected in the sample more than once the sample had to have been selected without replacement.
What is the sample?A sample is a subset of data drawn from a larger population by a researcher using a predetermined selection process. These components are referred to as sample points, sampling units, or observations.
If it is determined that no subscriber had been selected in the sample more than once, this means that each subscriber was only included once in the sample. This can only occur if the sample was selected without replacement, meaning that each subscriber was selected once and only once from the population frame.
Therefore, the correct answer is C. the sample had to have been selected without replacement.

96g + 80f and explain
Answer:
16(6g + 5f)
Step-by-step explanation:
To factor 96g + 80f, we must find the GCF of 96 and 80. We don't factor g and f since they're totally different and can't be factored.The GCF of 96 and 80 is 16.To factor the equation:
96g + 80f
16(6g + 5f)
Twelve people ordered calculators. The least expensive was $5.95 and the most expensive was $12.95. Half ordered a $9.95 calculator. Select the best estimate of the amount spent on calculators.(1 point)
$125
$90
$160
$140
Answer:
Round up all costs
Least expensive: $6
Most expensive: $13
Half (half of 12 people is 6) ordered $10 calculators so 6x10=$60
Other half
(6+13)/2= $9.5 round up to $10 so 6x10=$60
$60 + 60=$120 best estimate $125
Step-by-step explanation:
The required, best estimate of the amount spent on calculators is $125. Option A is correct.
What is rounding of values?The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.
Since half of the twelve people ordered a calculator costing $9.95, there are 6 such people. Let the remaining 6 people have ordered the cheapest calculator, which costs $5.95. Then the total amount spent on calculators is:
6 x $5.95 + 6 x $9.95 = $35.70 + $59.70 = $95.40
However, we also need to take into account the possibility that some people may have ordered more expensive calculators. We know that the most expensive calculator costs $12.95, so let's assume that all 12 people ordered this calculator. Then the total amount spent on calculators would be:
12 x $12.95 = $155.40
Since the actual amount spent is somewhere between $95.40 and $155.40, the best estimate of the amount spent on calculators is around the midpoint of these values:
($95.40 + $155.40) / 2 = $125.40
Therefore, the best estimate of the amount spent on calculators is $125.

What is the area of the quadrilateral and what is the perimeter
Answer:
Area of Trapezoid = (b1 + b2)h

Area = (9 in + 17 in) (3 in = 1/4 ft)

A = (26 in)(3 in)/2
A = 78 in2/2

Perimeter = bi + b2 + 2l
P = 9in + 17 in + 2(5 in)
P = 26 in + 10 in
P = 36 inches

Answer:
335 mm²
Step-by-step explanation:
This will be so easy, that you can do it in the future by yourself!
Okay let's start by splitting this figure, the easiest way seems to be by cutting off that little part, you know what just let me show a picture.
Okay you shuold be able to see the picture, so the small square has an area of 20, since 5 times 4 is 20 mm! The larger square has an area of 315!
How did I find this? Take that small 10mm in the side and add it to 5mm, that would be 15. 15 times the bottom the width, it would be 15 * 21. 15 times 21 is equal to 315.
Now, we add both those areas together, to get ourselves a nice little 335 mm²

What is angle M and N and the length of NP
Best answer gets brainliest!!!!
Answer:
3
Step-by-step explanation:
Answer:
Angle M and N is 45 degrees, and the length of NP is approximately 6 cm
Step-by-step explanation:
With angle P being 90 degrees. The angles of M and N, must add up to 90 degrees as well.
*triangles add up to a total of a 180 degrees, (180 - 90 = 90)
9 ÷ 2 = 45
So: ∠M = 45° and ∠N = 45°
To find the length of NP, use the pythagorean theorem.
a² + b² = c²
a = MP = 5
b = NP = x
c = MN = 7.8
(5)² = 25
(7.8)² = 60.48
25 + x² = 60.48
x² = 60.48 - 25
x² = 35.84
x = √35.84
x = 5.986 = 5.99
NP = 5.99 = 6

Measurements were taken from snails of the shell weights and the widths of the opercula. Plot a graph of opercula width (y-axis) versus shell weight (x-axis). Estimate the correlation coefficient and test to see if there is a significant association shell weights and the widths of the opercula. Use a 5% level of significance.
Opercula width
Shell weight (g) (mm)
12 10.1
10 9.0
7 5.5
14 9.9
11 8.3
8 8.5
10 8.0
9 6.4
6 6.2
13 8.1 2.306
Answer:
Yes,there is a significant association shell weight and the widths of the opercula
Step-by-step explanation:
Using a correlation Coefficient calculator :
Given the data above :
The Coefficient of correlation(r) obtained is :
0.7632
Obtaining the test statistic :
T = r² / √(1 - r²) / (n - 2)
T = 0.7632² / √(1 - 0.7632²) / (10 - 2)
T = 0.58247424 / 0.2284528
Test statistic = 2.550
The Pvalue from r score , N = 10
Pvalue(0.7632, 10) = 0.01022
α = 0.05
If Pvalue < α ; reject H0
Pvalue < α ; We conclude that there is a significant association shell weights and the widths of the opercula
