C is the approximant answer

Answer:

62.5ft

Step-by-step explanation:

It doesnt matter if there's bumps along the side, the height will still reach to the same point.

Using trigonometry we have a adjacent and the opposite.

Hypotenuse is opposite the right angle

Opposite is opposite the angle

Adjacent is the last side to remain

Soh Cah Toa

We'll be using toa (Tan) because o and a (opposite and adjacent)

rearranging the original formuma :

Side × tan(Angle)

80 × tan (38) =62.50285....ft

A. -4, -1, 2, and 5

Answer:

x = √810

Step-by-step explanation:

Using the leg rule, which is given as:

Hypotenuse/leg = leg/part

Thus:

Hypotenuse = 27 + 3 = 30

leg = x

Part = 27

Plug in the values

30/x = x/27

Cross multiply

x*x = 30*27

x² = 810

x = √810

Answer:

0.0764 = 7.64% approximate probability of obtaining a sample of 100 adults in which 65 or fewer own their home.

Step-by-step explanation:

To solve this question, we use the normal approximation to the binomial distribution.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Normal probability distribution

Problems of normally distributed distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].

According to the U.S. Census, the proportion of adults in a certain county who owned their own home was 0.71.

This means that [tex]p = 0.71[/tex]

Sample of 100:

This means that [tex]n = 100[/tex]

Mean

[tex]\mu = E(X) = np = 100*0.71 = 71[/tex]

Standard deviation:

[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{100*0.71*0.29} = 4.5376[/tex]

What represents the approximate probability of obtaining a sample of 100 adults in which 65 or fewer own their home, assuming that this section of the county has the same overall proportion of adults who own their home as does the entire county?

This is, using continuity correction, [tex]P(X \leq 65 - 0.5) = P(X \leq 64.5)[/tex], which is the pvalue of Z when X = 64.5. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{64.5 - 71}{4.5376}[/tex]

[tex]Z = -1.43[/tex]

[tex]Z = -1.43[/tex] has a pvalue of 0.0764

0.0764 = 7.64% approximate probability of obtaining a sample of 100 adults in which 65 or fewer own their home.

Answer:

a) [tex]\frac{3}{20}[/tex] and [tex]\frac{16}{20}[/tex] = [tex]\frac{19}{20}[/tex]

b) [tex]\frac{8}{21}[/tex] and [tex]\frac{18}{21}[/tex] = [tex]1\frac{5}{21}[/tex]

c) [tex]\frac{18}{72}[/tex] and [tex]\frac{32}{72}[/tex] = [tex]\frac{25}{36}[/tex]

Step-by-step explanation:

a) [tex]\frac{3}{20}[/tex] and [tex]\frac{4}{5}[/tex]

[tex]\frac{4}{5}[/tex] x 4 = [tex]\frac{16}{20}[/tex]

[tex]\frac{3}{20}[/tex] and [tex]\frac{16}{20}[/tex] = [tex]\frac{19}{20}[/tex]

b) [tex]\frac{8}{21}[/tex] and [tex]\frac{6}{7}[/tex]

[tex]\frac{6}{7}[/tex] x 3 = [tex]\frac{18}{21}[/tex]

[tex]\frac{8}{21}[/tex] and [tex]\frac{18}{21}[/tex] = [tex]1\frac{5}{21}[/tex]

c) [tex]\frac{2}{8}[/tex] and [tex]\frac{4}{9}[/tex]

[tex]\frac{2}{8}[/tex] x 9 = [tex]\frac{18}{72}[/tex]

[tex]\frac{4}{9}[/tex] x 8 = [tex]\frac{32}{72}[/tex]

[tex]\frac{18}{72}[/tex] and [tex]\frac{32}{72}[/tex] = [tex]\frac{25}{36}[/tex]

Answer: 7^5 or 7 to the fifth power.

Step-by-step explanation: This is an exponent meaning you count the 7’s and in the first picture there’s 5 7’s. This means that the number your putting to a power is the yellow box so that’s 7 and the exponent is 5 not 4 because if you did 7 to the first power it’s still 7 so it would be 7 to the 5th power or 7^5

Answer:

B. 24/5

Step-by-step explanation:

QR = 10

QT = 6

HI = 8

Quadrilateral QRST ~ quadrilateral HIJK, therefore, their corresponding side lengths would be proportional to each other.

This:

QR/HI = QT/HK

Plug in the values

10/8 = 6/HI

Cross multiply

10*HI = 8*6

10*HI = 48

Divide both sides by 10

HI = 48/10

HI = 24/5

Answer:

B. 25

Step-by-step explanation:

The computation of the no of adult tickets sold is shown below;

let us assume the number of child ticket be x

And, for adult ticket be y

Now as per the questions

x + y = 100

7.50x + 10y = 812.50

Multiply by 7.50x in equation 1

7.50x + 7.50y = 750

7.50x + 10y = 812.50

-2.50y = -62.50

y = 25

Hence, the number of adult ticket sold is 25
