Answer: angle x is 52°

Assuming the line JK is parallel to HI. That should be given.

Step-by-step explanation:

Angle JKA is congruent to angle HIA, so both measure 62°

Add measure of AHI to JKA.

66+62= 128.

Angles of a triangle always add up to 180° so you can subtract 128 from 180 to find x.

180-128= 52°

Answer:

The male students must you measure 'n' = 24

Step-by-step explanation:

Step(i):-

Given Population standard deviation = 2.5 inches

Given the margin of error = 1 inches

Step(ii):-

90% confidence interval of Margin of error is determined by

\(M.E = \frac{Z_{\frac{\alpha }{2} } S.D}{\sqrt{n} }\)

\(Z_{\frac{0.10}{2} } = Z_{0.05} = 1.96\)

\(1 = \frac{1.96 X 2.5}{\sqrt{n} }\)

cross multiplication , we get

√n  =  4.9

squaring on both sides , we get

n = 24.01≅ 24

Final answer:-

The male students must you measure 'n' = 24

The total number of male students is 24 and this can be determined by using the formula of margin of error.

Given :

The formula of margin of error can be used in order to determine the sample size. The formula of margin of error is given by:

\(\rm ME =\dfrac{ Z_{\frac{\alpha }{2}}\times \sigma}{\sqrt{n} }\)      ----- (1)

\(\rm Z_{\frac{0.1}{2}}=Z_{0.05} = 1.96\)

Now, substitute the known terms in the equation (1).

\(\rm 1 =\dfrac{ 1.96\times2.5}{\sqrt{n} }\)

Cross multiply in the above expression.

\(\rm \sqrt{n} = 1.96 \times 2.5\)

\(\rm \sqrt{n} = 4.9\)

n = 24.01

n \(\approx\) 24

So, the total number of male students is 24.

Answer:

Depends on whether you're looking for area or perimeter. Follow the equations below

Step-by-step explanation:

This depends on whether you're being asked to find perimeter of area

Perimeter is equal to 2(length) + 2(width)

In which case perimeter would be 2(4 + w) + 2(w)

Which can be simplified to 8 + 2w + 2w = 4w + 8

However, Area is equal to length times width

Which would be (4 + w) * w = 4w + w^2

Answer:

Step-by-step explanation:

The upper limit of the confidence Interval is: 1530.23

2) The lower limit of the confidence Interval is: 1478.32

The upper limit of the confidence Interval is: 15411.68

The formula to find the confidence interval is:

CI = x' ± z(σ/√n)

where:

CI is confidence interval

x' is sample mean

z is z-score at confidence level

σ is standard deviation

n is sample size

1) The parameters are:

σ = $234

x' = $1510

n = 362

z at 90% CL = 1.645

Thus:

CI = 1510 ± 1.645((234/√362)

CI = 1510 ± 20.23

CI = (1489.77, 1530.23)

2) The parameters are:

σ = $234

x' = $1510

n = 362

z at 99% CL = 2.576

Thus:

CI = 1510 ± 2.576((234/√362)

CI = 1510 ± 31.68

CI = (1478.32, 15411.68)

Answer:

The coordinates of B' are (-3,-15)

Step-by-step explanation:

We are given the point A(-3,-1) and we know it was dilated to the point A'(-9,-3) by some scale factor.

The scale factor can be found by dividing each coordinate of A' by the same coordinate of A. Let's call the factor as k:

k = -9/(-3) = 3

k = -3/(-1) = 3

Thus the scale factor is 3.

If we apply the same factor to B(-1,-5), we get the coordinates of B' as:

No. there is not a fixed number of trials. Hence, the correct option is B.

A variable with only two outcomes is said to be binary. Examples of binary categorical variables are sex (male/female) and having a tattoo (yes/no).

Each trial must be independent, meaning that it must have a defined number of trials and a constant success rate. Its probability needs to range from 0 to 1.

There are only two conceivable outcomes for each individual. They are either filtered or they are not. We are not interested in learning how many people were screened, though.

It is an inverse binomial, we want to know how many persons will be screened before 10, which is a binomial. Therefore, since there are an arbitrary number of trials, this is not a binomial equation, and option B provides the solution.

Therefore, there is not a fixed number of trials. Hence, the correct option is B.

The sale price of coat is $180 and the sale price of boot is $284 when 20% off a coat and a pair of boots are now  on sale.

Given that,

20% off a coat and a pair of boots are now  on sale. The coat normally sells for $225. The boots cost $130 on the open market.

We have to find the coat's sale price and what is the cost of the boots on sale.
We know that,

The formula for the sales price is S = P - PD

Where, S is sales price, P is the original price and D is the discount percent.

P = 225 and D = 20%

S = 225 - 225 × 20%

S = 225 - 45

S = $180 is the sale price of coat.

Now,

Total regular price = 225 + 130 = 355

S = 355 - 355 × 20%

S = $284 is the sale price of boots.

Therefore, The sale price of coat is $180 and the sale price of boot is $284.

c ≥ 6 and d > 4, the common solutions are all values of (c,d) that satisfy these two conditions simultaneously of inequalities

The given inequalities are -2(c-4)≤-4 and 1/2 d - 6 >-4

The first inequality is  -2(c-4)≤-4

-2c + 8 ≤ -4

Subtracting 8 from both sides, we get:

-2c ≤ -12

Dividing both sides by -2

c ≥ 6

Now, let's look at the second inequality:

1/2 d - 6 > -4

Adding 6 to both sides, we get:

Mean of the set of numbers = 23

Median of the set of numbers = 23

Mode of the set of numbers = 16, 19, 23, 26, 31

The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. This is what is most often meant by an average. The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list.

Given numbers,

Putting in Ascending order

16, 19, 23, 26, 31

No. of elements N = 5

Mean = (26 + 31 + 19 + 23 + 16)/5

Mean = 115/5

Mean = 23

Since N = 5 (Odd)

Median = (N+1)/2th term

            = (5+1)/2th term

            = 6/2th term

"A kite has 4 interior angles and the sum of these interior angles is 360°. In these angles, it has one pair of opposite angles that are obtuse angles and are equal." - Cue math

Ok, so the two acute angles add up to 118 degrees, and in order to find the remaining angles we need, subtract 118 from 360 to get 242. Because the two obtuse angles are equivalent, divide 242 by 2 to get the measure of each.

The length of the side of the square in simplest form is 2sqrt(14).

The area of a square is given by the formula \(A = s^2\), where A is the area and s is the length of a side.

We are given that the area of the square is 56 units, so we can set up the equation:

\(56 = s^2\)

To solve for s, we can take the square root of both sides of the equation:

sqrt(56) = \(sqrt(s^2)\)

We can simplify the square root of 56 by factoring it:

sqrt(56) = sqrt(222*7) = 2sqrt(14)

So, we have:

2sqrt(14) = s

This is an improper fraction because the numerator is larger than the denominator. Therefore, the length of the side of the square in simplest form is 2sqrt(14).
