Answer:

d. Cos B = 9/41

Step-by-step explanation:

Recall, SOHCAHTOA.

Cos B = Adjacent length / Hypotenuse length

Adjacent length to reference angle B = 27

Hypotenuse length = 123

Cos B = 27/123 = 9/41

Answer:

22% probability the student is a junior.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes:

The table says that:

There are 4 + 6 + 2 + 2 + 3 + 4 + 6 + 6 + 3 = 36 total students.

2 + 6 = 8 are juniors.

If a student is selected at random, find the probability the student is a junior.

8/36 = 0.2222 = 22.22%

Rounding to the nearest whole percent, 22% probability the student is a junior.

x < -8

Step-by-step explanation:

−3x>24

Divide each side by negative 3, remembering to flip the inequality

-3x/-3 < 24/-3

x < -8

Answer:

x<-8

Step-by-step explanation:

−3x>24

Multiply both sides by (-1) (reverse the inequality)

(-3x)(-1)<24(-1)

Simplify;

3x<-24

Divide both sides by 3

3x/3<-24/3

Simplify

3x/3<-24/3

Simplify; 3x/3

=x

Simplify; -24/3

Divide the numbers;24/3=8

=-8

x<-8

D. Completely randomized design

Step-by-step explanation:

Based on the description given about the experiment above and the manner in which the subjects were assigned to each of the treatment groups available, we can deduce that the study was conducted using a completely randomized design. The subjects weren't matched or blocked for any variable such as sex, height, age or any other variable. They were just evenly split randomly into the two available treatment levels ( those who receive the treatment and the placebo) group. With this design, all subjects have an equal chance of being in any of the two groups and the selection bias is almost totally eliminated using this sort of design as errors are being considered as arising from experimental faults.

Answer:

[tex]46 \frac{7}{8} \: cubic \: feet[/tex]

Step-by-step explanation:

[tex]\boxed{volume \: of \: prism = base \: area \: \times height}[/tex]

Base area= length ×width

Let's convert all the mixed numbers into improper fraction for easier calculation.

Width

= 7½

[tex] = \frac{7(2)}{2} + \frac{1}{2} [/tex]

[tex] = \frac{14}{2} + \frac{1}{2} [/tex]

[tex] = \frac{15}{2} ft[/tex]

Height

= 1¼

[tex] = \frac{4}{4} + \frac{1}{4} [/tex]

[tex] = \frac{5}{4} ft[/tex]

Volume of prism

[tex] = 5 \times \frac{15}{2} \times \frac{5}{4} [/tex]

[tex] = \frac{375}{8} [/tex]

[tex] = 46 \frac{7}{8} \: ft {}^{3} [/tex]

The required probability that she works on Shift 2 is 3/8. Option C is correct.

The table below gives the number of men and women who work on the three shifts at Factory X. Each worker at the factory work on exactly one of the shifts. A worker is to be chosen at random from the factory. If the worker chosen is a woman, what is the probability that she works on Shift2 is to be determined.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

The total number of women working in all the 3 shifts = 560
number of women working in shift 2 = 210
probability of women chosen to work in shift 2 = 210/560
                                                                    = 3/8

Thus, the required probability that she works on Shift 2 is 3/8. Option C is correct.

Step-by-step explanation:

median mean the middle number (number that appears to be in the middle)

you were given a series of numbers, like in this question is quite easy because you were given five numbers. so you cancel out two from the left and two from your right the remainder is 61 and that's your median.

Answer:

c

Step-by-step explanation:

first, find the area of the rectangle thing,

A = lw

14 x 8

112

but, there is a semicircle in it so you need to subtract that from it:

A = πr^2/2

A = π(4)^2/2

A = π16/2

A = 8π

A ≈ 25.132741228718346

then subtract that area from the area of the rectangle:

112 - 25.132741228718346

86.867258771281654

or about 89.9

The answers of the final equation would be -8 & 5 ,but only 5 is accepted 'cause if u insert -8 as X , under the rad , you will have (-) which is incorrect .

Step-by-step explanation:

Hope my explanation helped u , good luck . ♡

The solution of the given equation is w = 8.

A solution to an equation is a number that can be plugged in for the variable to make a true number statement

Splitting of the middle term is that we have to rewrite the middle term of the quadratic expression as the sum or difference of the two terms.

We have an equation

[tex]\sqrt{w^{2}+7w-39 } =\sqrt{10w+1}[/tex]

To find the solution of the above equation,

Square both the sides of the above equation and find the value of x by splitting the middle term.

[tex]\implies (\sqrt{w^{2} +7w-39} )^{2} =(\sqrt{10w+1} )^{2}[/tex]

[tex]\implies w^{2} + 7w - 39 = 10w + 1[/tex]

[tex]\implies w^{2} + 7w - 10w -39-1= 0[/tex]

[tex]\implies w^{2} -3w - 40 = 0[/tex]

[tex]\implies w^{2} -8w +5w - 40=0[/tex]

[tex]\implies w(w-8)+5(w-8)=0[/tex]

[tex]\implies (w+5)(w-8)=0[/tex]

[tex]\implies w = 8 \ or\ -5[/tex]

w = -5 is not possible because the root will give the imaginary values.

Hence, the value of w is 8.

Thus, option D is correct.

Answer:

2.576

Step-by-step explanation:

The Z critical value for constructing a 99% confidence interval for a proportion is 2.58.

A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.

For the given situation,

The confidence interval for a proportion = 99% = 0.99

Area to the left of a positive Z score in this standard normal distribution table is

⇒ [tex]\frac{1+confidence level}{2}[/tex]

⇒ [tex]\frac{1+0.99}{2}[/tex]

⇒ [tex]\frac{1.99}{2}[/tex]

⇒ [tex]0.995[/tex]

The corresponding Z score in the table for 0.995 is

⇒ [tex]2.5+0.08[/tex]

⇒ [tex]2.58[/tex]

Hence we can conclude that the Z critical value for constructing a 99% confidence interval for a proportion is 2.58.

Step-by-step explanation:

Answer:

y = 218

Step-by-step explanation:

Mean = (Sum of all numbers)/(How many numbers present)

27 = (20 + 2y + 25 + y + 30)/27

27 = (3y + 75)/27

3y + 75 = 729

3y = 729 - 75

3y = 654

y = 218
