Conclusion There Select an answer appear to be enough evidence to support the claim that the.

(to 2 decimals)
Our calculation led to a P-value of .516, exceeding the predefined significance level of 0.01 which thereby disproves any evidence indicating individuals whose applications were unsuccessful came from a group whose members had higher mean ages than those who were successful.
How to solveWe will use a two-sample t-test.
Unsuccessful applicants (Group 1):
n1 = 23
Mean1 (x1) = 41.6
Standard deviation1 (s1) = 14.5
Successful applicants (Group 2):
n2 = 25
Mean2 (x2) = 39.7
Standard deviation2 (s2) = 5.4
Claim: μ1 > μ2
Opposite: μ1 ≤ μ2
In order to compare the means of two independent samples, a two-sample t-test is used.
The initial step involves calculating both the pooled variance (Sp^2) and standard error (SE).
To calculate Sp^2, use the formula ((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2),
As per our specific data set regarding sample one consisting of 22 values with an average age of 41.6 years old, and sample two having 24 values averaging at 39.7 years old, we derived a pooled variance value of 120.569.
After that, employ the equation SE = √((Sp^2/n1) + (Sp^2/n2)), which yields a value of 3.685 via inputting the aforementioned values.
Using these results enables us to take the difference of the two averages divided by SE in a simplified manner giving a t-score equal to .516.
In light of this test possessing a significance level of 0.01 and utilizing only one tail, a comparison of the calculated t-score to the t-distribution table must occur; using a critical t-value of 2.410 wherein the degrees of freedom are required to be 46.
Our calculation led to a P-value of .516, exceeding the predefined significance level of 0.01 which thereby disproves any evidence indicating individuals whose applications were unsuccessful came from a group whose members had higher mean ages than those who were successful.

First, we need to isolate the radical term on one side of the equation:
7 + V(-36 - 5x) = 250
V(-36 - 5x) = 243 (subtract 7 from both sides)
-36 - 5x = 243^2 (square both sides)
-36 - 5x = 59049
-5x = 59049 + 36
-5x = 59085

The solution is, the value of the variables are x = 40 and, y = 160.
Notice that "x" and "3x+20" are supplementary angles so their sum is 180°
(x) + (3x + 20) = 180
4x + 20 = 180
4x = 160
x = 40
To solve for "y", you have 2 options: either notice that "x" and "y-20" are supplementary angles so their sum is 180° or notice that "3x + 20" and "y - 20" are vertical angles so are equal to each other. I am going to solve using the first option because it is less work.
(x) + (y - 20) = 180°

The system of equations -9x+8y = 9x and 7y+8=8x is linear.
A system of equations is considered linear if each equation in the system is linear, meaning that the highest power of any variable in each equation is 1.
In this case, the first equation -9x+8y = 9x is linear because the highest power of any variable is 1 (x is raised to the first power).
Similarly, the second equation 7y+8=8x is also linear because the highest power of any variable is 1 (x is raised to the first power and y is not raised to any power).

log₂(3(x + 4)) = log₂(8) + log₂(2x − 5)
log₂(3x + 12) = log₂(2³) + log₂(2x − 5) .......(2³ = 8)
log₂(3x + 12) = 3log₂(2) + log₂(2x − 5)
log₂(3x + 12) = (3 × 1) + log₂(2x − 5)
log₂(3x + 12) - log₂(2x − 5) = 3
Applying power identity of logarithm to -log₂(2x − 5) we get,
-log₂(2x − 5) = 1 / [log₂(2x − 5)]
So, our equation becomes,
log₂(3x + 12) + [1 / log₂(2x − 5)] = 3
Applying product rule of logarithm to log₂(3x + 12) + [1 / log₂(2x − 5)] we get, log₂(3x + 12) + [1 / log₂(2x − 5)] = log₂[(3x + 12) / (2x − 5)]
So, our equation becomes,
log₂[(3x + 12) / (2x − 5)] = 3
Now, exponentiate both sides.
(3x + 12) / (2x - 5) = 2³
(3x + 12) / (2x - 5) = 8
(3x + 12) = 8(2x - 5)
3x + 12 = 16x - 40
13x = 52
x = 4
This is the required value of x.

Lena must choose a number between 67 and 113 that is a multiple of 4,6, and 8 .
96 is the smallest number that is a multiple of 4, 6, and 8 and is between 67 and 113.
Given that, Lena must choose a number between 67 and 113 that is a multiple of 4,6, and 8.
Start listing the multiples of 4 between 67 and 113, which are 68, 72, 76, 80, 84, 88, 92, 96, 100, 104, and 108.
We can then narrow down the list by looking for the multiples of 6, which are 72, 78, 84, 90, 96, and 102, and the multiples of 8, which are 72, 80, 88, 96, 104, and 112.
Since 96 is the smallest number that is a multiple of 4, 6, and 8 and is between 67 and 113.
Therefore, 96 is the smallest number that is a multiple of 4, 6, and 8 and is between 67 and 113.

What are the trigonometric ratios?The three trigonometric ratios are the sine, the cosine and the tangent, and they are defined as follows:
Sine of angle = length of opposite side to the angle divided by the length of the hypotenuse.Cosine of angle = length of adjacent side to the angle divided by the length of the hypotenuse.Tangent of angle = length of opposite side to the angle divided by the length of the adjacent side to the angle.For the angle of 24º, we have that:
The adjacent side is of 24 feet.The opposite side is the height.Hence the height is obtained as follows:
tan(24º) = h/24
h = 24 x tangent of 24 degrees
h = 10.7 ft.

The measure of the angle m∠ZYX of the trapezoid is equal to 139°
What is a trapezoid?A trapezoid is a quadrilateral with two parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs. The adjacent angles of the trapezium are supplementary, so their sum is equal to 180°.
3x + 19 + x + 1 = 180°
4x + 20 = 180°
4x = 180 - 20 {collect like terms}
4x = 160
x = 160/4 {divide through by 4}
x = 40
m∠ZYX = 3(40) + 19 = 139°.
WXYZ is a trapezoid. Equation used to solve for x is (3x + 19) + (x + 1) = 180° because the angles m∠XYZ and m∠WXY are adjacent angles.
