Step-by-step explanation:

if you do the math you end up with 49 which is a perfect square of 7

The expression that is equivalent to a perfect square in the options is 34 + 18 ÷ 3².

A perfect square is the number derived when a number is multiplied by itself. For example, 9 is a perfect square because 3 multiplied by 3 is equal to 9.

3 + 2² x 7 = 31

(80 + 4)÷ 4 = 21

34 + 18 ÷ 3² = 36

3²+ 6 x 5 ÷ 3 = 19

Answer:

there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.

Step-by-step explanation:

H0 : μw = μm

H1: μw < μm

The test statistic :

(x1 - x2) / sqrt[(sp²/n1 + sp²/n2)]

df1 = 14 - 1 = 13

df2 = 17 - 1 = 16

Pooled variance = Sp² = (df1*s1² + df2*s2²) ÷ (n1 + n2 - 2)

Sp² = ((13*4^2) + (16*4.2^2)) ÷ (13 + 16)

Sp² = 16.90

t = (12.9 - 16.4) ÷ sqrt((16.90/14 + 16.90/17))

t = - 3.5 ÷ 1.4836645

t = - 2.359

Using the Pvalue from Tscore ; at 95% ; df = 29

Pvalue = 0.0126

Pvalue < α

0.0126 < 0.05 ;

Hence, we reject the null and conclude that there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.

Years, Inning and saves are statistically significant ; ERA is not.

Step-by-step explanation:

Earning for staying one additional year :

Multiply slope value of years * 1 = 0.052 * 1 * 100 % = 5.2% (earning increases by 5.2%)

Relives with 10 more saves :

10 * 0.0032 * 100% = 3.2% (earning increases by 3.2%)

Having 100 more innings :

100 * 0.00089 * 100% = 8.9%

If ERA is reduced by 1.5 ; earning will increase by (0.0085*100)% * 1.5 = 1.275%

B.) At 5% level of confidence :

α = 1.64

Years = 0.052/0.026=2

Inning = 0.00089/0.00020 = 4.45

Saves = 0.0032/0.0018 = 1.78

ERA = 0.0085/0.0168 = 0.51

Years, Inning and saves are statistically significant as they are greater than α ; As for ERA, it is not statistically significant (0.51 < 1.64)

Answer:

<EFC and <DCF

Step-by-step explanation:

Alternate interior angles: Angles that are inside the parallel lines and are opposite from each other

<DCA and <DCF are supplementary angles meaning they add up to 180 degrees.

<EFH and <GFC are vertical angles and both angles are not inside the parallel lines.

<BCF and <GFH are not alternate interior angles because both the angles aren't inside the parallel lines.

<EFC and <DCF are alternate interior angles because they are on opposite sides of the transversal and inside the parallel lines.

Answer:

v = -3i - 2j

Step-by-step explanation:

Vector given two points:

Given two points, a vector is the subtraction of the terminal point by the initial point.

In this question:

Initial point: (-1, 4)

Terminal point: (-4, 2)

So

v = (-4,2) - (-1, 4) = (-4 - (-1), 2 - 4) = (-3,-2)

The vector is v = (-3,-2)

In component form:

xvalue is i, yvalue j. So

v = -3i - 2j

Answer:

$30 per Ticket

Step-by-step explanation:

There are 3 friends coming along you so that means you have to divide one number by 3. You have a $20 coupon so that meant you had to subtract 20 from 120. 20-120=100.

Now, you have to divide 100 by the 3 friends then add 5 to each number.

3 divided by 100=25+5=30

So, $30 is your answer

Answer and Step-by-step explanation:

To find the mean, you have to add all of the data together, then divide by the amount that there is.

So, when adding together the data, we get 66. We have 6 values, so we will divide 66 by 6.

66 divided by 6 is 11.

The mean of the data set is 11.

Answer:

60.5m^2

Step-by-step explanation:

the area of the square

=121m^2

the area of triangle

=11m×11m÷2

=121m^2÷2

=60.5m^2

the area of the shaded region

=121m^2-60.5m^2

=60.5m^2

Answer:

0.7995 = 79.95% probability that the sample will contain at least three defectives.

Step-by-step explanation:

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].

Suppose that a random sample of 20 items is selected from the machine.

This means that [tex]n = 20[/tex]

The machine produces 20% defectives

This means that [tex]p = 0.2[/tex]

Mean and standard deviation:

[tex]\mu = E(X) = np = 20*0.2 = 4[/tex]

[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{20*0.2*0.8} = 1.79[/tex]

Probability that the sample will contain at least three defectives

Using continuity correction, this is [tex]P(X \geq 3 - 0.5) = P(X \geq 2.5)[/tex], which is 1 subtracted by the pvalue of Z when X = 2.5. So

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

[tex]Z = \frac{2.5 - 4}{1.79}[/tex]

[tex]Z = -0.84[/tex]

[tex]Z = -0.84[/tex] has a pvalue of 0.2005

1 - 0.2005 = 0.7995

0.7995 = 79.95% probability that the sample will contain at least three defectives.

Answer:

37.7

Step-by-step explanation:

If the diagonal length and the television are given as 76 inches and 66 inches, the obtained length will be 37.68

In two-dimensional planning geometry, it is the region that the rectangle occupies. It is described as a type of two-dimensional geometry where the angle between neighboring sides is 90 degrees. It is a specific kind of quadrilateral.

The following formula can be used to determine a rectangle's area:

Rectangle area = length x width

It given that, the diagonal length of the TV is 76 inches, the width of the TV is 66 inches,

We have to find the length of the television. Apply the Pythagoras theorem,

AC²=AB²+BC²

76²=66²+BC²

BC²=76²-66²

BC²=1420

BC=√1420

BC=37.68

Thus, the obtained length of the television will be 37.68

s ≤ 20

Step-by-step explanation:

The speed limit refers to the maximum velocity a vehicle is allowed to move. Therefore, for a certain street like the one in the scenario abive, with a speed limit of 20 miles per hour, then, the maximum allowable speed on the highway is 20 miles per hour. Meaning vehicles can move at that speed or below. However, moving above that speed is a violation of the speed limit rule. Hence. The speed limit could be represented by the inequality :

Speed limit is less than or equal to 20 miles per hour
