Answer:

d. We assume that the new golf ball has an average driving distance that is greater than or equal to that of the current ball. However, if the current model has a mean driving distance that is significantly longer, then we should reject our assumption.

Step-by-step explanation:

Given that :

μ1=population mean driving distance for the current golf ball

μ2=population mean driving distance for the new golf ball

H0 : μ1 - μ2 ≤ 0

H1 : μ1 - μ2 > 0

The Null hypothesis assumes that the average driving distance of the current golf ball is less than or equal to the average driving distance of the current golf ball

For the Alternative ; If there is significant evidence that the average driving distance of the current golf ball is greater or longer than the average driving distance of the new golf ball ;then we reject our initial claim (the Null hypothesis).

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:

( 3 , 9 )

Step-by-step explanation:

First, add  

3

to each segment of the system of inequalities to isolate the  

x  term while keeping the system balanced:

3 + 3 < 2 x − 3 + 3 < 15 + 3 6 2 x − 0 < 18  6 < 2 x < 18

, divide each segment by  2

to solve for  x

while keeping the system balanced:

6 2 < 2 x 2 < 18  2  3 < 2 x 2 < 9  3 < x <  9  Or  x > 3 ;  x< 9

Answer:

The amount of money, to the nearest cent, in the account after 3 years will be $ 7028.56

Step-by-step explanation:

The amount is given by

[tex]V = Pe^{rt}[/tex]

Given P = $6520

r = 2.5%

t = 3 years

Substituting the given values, we get -

[tex]V = 6520 * e^{2.5*3/100 }\\V = 6520 * 1.078\\V = 7028.56[/tex]

The amount of money, to the nearest cent, in the account after 3 years will be $ 7028.56

Answer:

y=50x+0

Step-by-step explanation:

y=mx+b is y-intercept form

I will make x= hours and y= distance (miles)

every 1 you add to x has to represent 50 miles

for the y intercept, it was unspecified so I assumed 0

Hope this helps :)

Answer:

y=50x

Step-by-step explanation:

Answer:

192°

Step-by-step explanation:

✔️First, find the value of x:

<G + <T = 180° (opposite angles of an inscribed cyclic quadrilateral are supplementary)

12 + 6x + 5x + 14 = 180 (substitution)

Add like terms

11x + 26 = 180

11x = 180 - 26

11x = 154

x = 154/11

x = 14

✔️m<G = ½(m(FH)) (inscribed angle is ½ of the measure of intercepted arc)

Therefore,

m(FH) = 2(m<G)

m(FH) = 2(12 + 6x) (substitution)

Plug in the value of x

m(FH) = 2(12 + 6*14) = 2(12 + 84) = 192°

Answer:

-angle C is 90°

-therefore angle A + angle B is,

180° - 90° = 90°

Answer:

60.5 mL

Step-by-step explanation:

Since 17.7% of the solution is acid, and we have 342 mL in total, we just multiply 342 x 0.177 to get 60.5 mL of acid.

Answer:

110,000 (suv) to be shipped to New York City

Step-by-step explanation:

We know that there are 180,000 (suv) to be shipped in total. We also know that there are two cities which these (suv) must be shipped to. So, that is 180,000 (suv) to be shipped to two cities. Let's right a true equation with this information:

Let n represent the number of (suv) to be shipped to New York City and b represent the number of (suv) to be shipped to Boston.

n + b = 180,000

Now, we also know that the number of (suv) to be shipped to New York City is 40,000 greater than the number of (suv) to be shipped to Boston. So, we can write another true equation (for the sake of convenience, let's write it in terms of b rather than in terms of n):

b = n - 40,000

Now that we have a value for b in terms of n, we can plug this value into b in our first equation:

n + (n - 40,000) = 180,000

From here, we can solve:

n + n - 40,000 = 180,000

2n - 40,000 = 180,000

2n = 220,000

n = 110,000

Thus, we have our final answer.

SMI SABADO VA MUY BIEN DAME CORONA PLISSSSSSSSSSSSS

Step-by-step explanation:

Answer:

Yes, you can make a triangle with it

Step-by-step explanation:

Given

[tex]Lengths: 9in, 4in, 6in[/tex]

Required

Do the lengths form a valid triangle

To do this, we make use of triangle inequality theorem which states that;

For sides a, b and c;

[tex]a + b > c[/tex]

[tex]b + c >a[/tex]

[tex]a + c > b[/tex]

So, we have:

[tex]9 + 4 > 6[/tex] -- true

[tex]4 + 6 > 9[/tex] -- true

[tex]6 + 9 > 4[/tex] -- true

Since all the inequalities are true, then the sides form a valid triangle

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.

b. g(x)...

range: b. (-infinity, 4}

Option (B) is the correct option.

"Graphing functions is drawing the curve that represents the function on the coordinate plane. If a curve (graph) represents a function, then every point on the curve satisfies the function equation".

For the given situation,

[tex]f(x) ={x+6 x < -4x^2, -2 6- x, x > 4[/tex]

[tex]g(x)={x+6, x < -2x^2, -2 6-x, x > 2[/tex]

[tex]h(x)={x+4, x < -2x^2, -2 4-x, x > 2[/tex]

Plot the graph for the given functions [tex]f(x), g(x), h(x)[/tex].

After plotting all the functions, the function [tex]g(x)[/tex] describes the graph shown.

Hence, option (B) is the correct option.

Answer:

189/8 cm^3

Step-by-step explanation:

Given data

Base= 7/2 cm

Hieght= 3/2cm

Length= 9/2cm

We know that the expression for volume is

Volume = L*B*H

substitute our data

Volume= 7/2*3/2*9/2

Volume= 189/8 cm^3

Hence the volume is 189/8 cm^3
