If the scale factor between trapezoid ABCD and trapezoid is GHIJ is 2, how many feet will side GJ be?
Kindly find required figure in the picture attached below :
Answer:
14 feets
Step-by-step explanation:
From Trapezoid ABCD ;
The longer base, AD = 7 feets
Shorter Base ; BC = 5 feets
The Trapezoid GHIJ
Shorter Base = HI
Longer base = GJ
Given that the scale factor between ABCD and GHIJ is 2 ; then
GJ is similar to AD
Hence, side GJ = 2 * length of AD
GJ = 2 * 7 = 14 feets

NEED HELP ASAP TAKING TEST A refrigeration unit at a restaurant is supposed to be kept at 40°F. An inspector would like to test the hypotheses H Subscript 0 Baseline: mu = 40 versus H Subscript alpha Baseline: mu not-equals40 where μ = the true mean temperature for all times of the day. A 98% confidence interval based upon a random sample of 40 temperatures is 40.5 degrees to 42.1 degrees. Using the interval, what decision should be made?
The null hypothesis should be rejected at the Alpha = 0.01 level.
The null hypothesis should be rejected at the Alpha = 0.02 level.
The null hypothesis should not be rejected at the Alpha = 0.05 level.
The null hypothesis should not be rejected at the Alpha = 0.10 level.
Answer:
,, the null hypothesis should be rejected at the alpha equals 0.02 level

Use the exterior angle theorem to find the value of x in the triangle below.
A
x = 7
B
x = 5
C
x = 12
D
x = 15
Answer:
Option A
Step-by-step explanation:
By using the definition of an exterior angle of a triangle,
"Measure of the exterior angle of a triangle is equal to the sum of measures of the opposite interior angles"
m∠STP = m∠SWT + m∠STW
Substitute the measures of the angles from the picture attached,
15x = (7x + 1) + (7x + 6)
15x = (7x + 7x) + (1 + 6)
15x = 14x + 7
15x - 14x = 7
x = 7
Therefore, Option A will be the correct option.
A new test is developed to test for a certain allergy, giving "positive" or "negative" results to indicate that a person does or does not have the allergy. For a person who has the allergy, the test will give a positive result 82% of the time and a negative result (false negative) 18% of the time. For a person who does not have the allergy, the test will give a positive result (false positive) 10% of the time and a negative result 90% of the time. A study included a population of 10,000 people, and 1% of those studied where known to have the allergy. Fill in the missing values in the table below, and complete the statements that follow. Round the percentage to the nearest tenth, if necessary.
Answer:
the first blank is 82, the second blank is 8,910. I got that third blank wrong and it should be 7.1 I think. and the last block is should not. to find the third box all you need to do is:82+990=1,072 then divide 82 by 1,072 and round to the nearest tenthAnswer:

a). Write an exponential decay function to represent this situation.
b). What will be the profits in 8 years? Round your answer to the nearest dollar.
10 Points question
Answer:
5000 X (0.96)^n
$3607
Step-by-step explanation:
Profit decreases at a rate of 6% per year = 100 - 6 = 96%
In year 1, profit would be = 5000 x 0.96 = 4800
In year 2 = 5000 x 0.96^2 =
5000 X (0.96)^n
5000 X (0.96)^8 = $3607

Clay surveys members of his class to find out how many televisions they have in their homes. The thirteen responses he received are shown in the table. Which statement is true?
A) The mean is less than the mode.
B) The mean is less than the range.
C) The mean is greater than the range.
D) The median is greater than the mode.
Answer:
B, the mean is less than the range
Step-by-step explanation:
mean is 3.38 (rounded)
mode is 3
median is 3
range is 5
The mean is 3.38 and the range is 5, So the mean is less than the range. Option B is the correct one.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Mean = [tex]\frac{1+5+2+3+4+6+3+1+3+4+3+5+4}{13}[/tex]
The mean is 3.38 (rounded)
Median represents the middle value of the given data when arranged in a particular order.
So, the Median would be 3.
Mode is that number that appears most frequently in the given set of data.
So, the Mode would be 3.
The range of a given set of data is the difference between the largest value and the smallest value.
So, the range would be 5

The diameter, D, of a sphere is 16.6 m. Calculate the sphere's volume, V. Use the value 3.14 forn, and round your answer to the nearest tenth. (Do not round any intermediate computations.) 3 Х ?
Answer:
[tex]2395.1\:\mathrm{m^3}[/tex]
Step-by-step explanation:
The volume of a sphere is given by [tex]4\pi r^3[/tex]. Since a radius is half a diameter, the radius of the sphere is [tex]\frac{16.6}{2}=8.3[/tex].
Substituting values, we have:
[tex]V=\frac{4}{3}\pi (8.3^3)\approx \boxed{2395.1}[/tex]
A study by the department of education of a certain state was trying to determine the
mean SAT scores of the graduating high school seniors. The study found that the
mean SAT score was 447 with a margin of error of 21. Write a confidence interval for
the true mean SAT score of the graduating high school seniors.
Answer:
(426 ; 468)
Step-by-step explanation:
Confidence interval :
Mean score ± margin of error
Margin of Error = 21
Mean SAT score = 447
Hence,
447 ± 21
Lower boundary = 447 - 21 = 426
Upper boundary = 447 + 21 = 468
(426 ; 468)

The vertex of a quadratic function is (5,-6), what is the equation of the axis of symmetry in this function?
Answer:
x = 5
Step-by-step explanation:
A quadratic equation:
f(x) = y = a*x^2 + b*x + c
Has a vertex in a point:
(h, k) such that:
h = -b/2a
and:
k = f(-b/2a)
And the axis of symmetry (this is the line that cuts the graph in two halves) is:
x = h.
In this case, the vertex is (5, -6)
Then the axis of symmetry is:
x = 5.

Step-by-step explanation:
CIRCLE
First we want to find the area of the circle which would be:
\pi r^{2}
3.14159265359 x 2^{2}
3.14159265359 x 4cm
= 12.5663706144cm^{2} /2 (must divide by two because it is half of a circle)
= 6.28318530718cm^{2}
RECTANGLE/SQUARE
Find the area of the square.
AREA = L x W
Length = 2cm + ?
Width = 6cm
To find the length we must use the diameter of the circle (which is the radius but times it by 2)
To find diameter: r x 2
= 2cm x 2
= 4cm
Length = 4 + 2 = 6cm
Width = 6 cm
Area (Length x Width) = 6cm x 6cm
= 36cm^{2}
TOTAL AREA:
Just add the area of the circle and the area of the square together.
Area total = 36cm^{2} + 6.28318530718cm^{2}
= 42.2831853072cm^{2}
* Also round your total answer to the nearest tenth or hundreth if needed to do so.
