Answer:

The probability is that he hits 5.6 out of 7 attempts.

Step-by-step explanation:

Given that an archer hits his target 80% of the time, if he shoots 7 arrows, to determine what is the probability of each event, the following calculation must be performed:

7 x 80/100 = X

560/100 = X

5.6 = X

Therefore, the probability is that he hits 5.6 out of 7 attempts.

Point Q is the center of dilation.

Rectangle H I J K is dilated to create rectangle H prime I prime J prime K prime.

The length of H prime I prime is 32 inches. The length of I prime J prime is 24 inches.

Sylvia enlarged a photo to make a 24 x 32-inch poster using the dilation DQ,4.

Answer:

The p-value of the test is 0.0416 < 0.05, which means that the null hypothesis is rejected.

Step-by-step explanation:

The engineer designed the valve such that it would produce a mean pressure of 5.7 pounds/square inch. It is believed that the valve performs above the specifications.

At the null hypothesis, we test that the mean is the specification value of 5.7, that is:

[tex]H_0: \mu = 5.7[/tex]

At the alternate hypothesis, we test that the mean is above the specifications, that is, above 5.7. So:

[tex]H_a: \mu > 5.7[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

5.7 is tested at the null hypothesis:

This means that [tex]\mu = 5.7[/tex]

The valve was tested on 8 engines and the mean pressure was 6.2 pounds/square inch with a variance of 0.49.

This means that [tex]n = 8, X = 6.2, s = \sqrt{0.49} = 0.7[/tex]

Test statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{6.2 - 5.7}{\frac{0.7}{\sqrt{8}}}[/tex]

[tex]t = 2.02[/tex]

P-value of the test and decision:

The p-value of the test is the probability of finding a sample mean above 6.2, which is the p-value of t = 2.02, using a right-tailed test with 8 - 1 = 7 degrees of freedom.

With the help of a calculator, this p-value is 0.0416.

The p-value of the test is 0.0416 < 0.05, which means that the null hypothesis is rejected.

Answer:

The value of [tex]y[/tex] when the value of [tex]x[/tex] is multiplied by [tex]\frac{1}{2}[/tex] is [tex]\frac{5}{8}[/tex].

Step-by-step explanation:

According to the statement, we have the following relationship:

[tex]y = k\cdot x^{3}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]k[/tex] - Proportionality constant.

We can eliminate the proportionality constant by constructing the following relationship:

[tex]\frac{y_{2}}{y_{1}} = \left(\frac{x_{2}}{x_{1}} \right)^{3}[/tex]

If we know that [tex]y_{1} = y[/tex], [tex]y_{2} = 5[/tex], [tex]x_{2} = x_{o}[/tex] and [tex]x_{1} = \frac{1}{2}\cdot x_{o}[/tex], then the value of [tex]y[/tex] when the value of [tex]x[/tex] is multiplied by [tex]\frac{1}{2}[/tex] is:

[tex]\frac{5}{y} = \left(\frac{x_{o}}{\frac{1}{2}\cdot x_{o} } \right)^{3}[/tex]

[tex]\frac{5}{y} = 8[/tex]

[tex]y = \frac{5}{8}[/tex]

The value of [tex]y[/tex] when the value of [tex]x[/tex] is multiplied by [tex]\frac{1}{2}[/tex] is [tex]\frac{5}{8}[/tex].

Answer:

Step-by-step explanation:

for a lot of math classes they just tell you  "don't take the square root of a negative number"   Then when you see this   [tex]\sqrt{-5}[/tex]  it looks all wrong.  But,  just think of the two things under the radical as

[tex]\sqrt{-1*5}[/tex]

now, take the  -1 out of the square root as   "  i  "

i[tex]\sqrt{5}[/tex]

Answer:

%50

Step-by-step explanation:

Answer:

[tex]\frac{1}{2}[/tex], 50%, or 0.5.

Step-by-step explanation:

Well, there are six possible outcomes, and we are looking for the probability of getting a number greater than three. There are three possible outcomes of getting a number greater than three, which makes the probability of getting the desired outcome look somewhat like the following fraction:

[tex]\frac{3}{6}[/tex] (or simplified, [tex]\frac{1}{2}[/tex])

Anyways, now that we have the outcome in the form of a fraction, we can convert it to percent (50%) or decimal form (0.5).

Step-by-step explanation:

A randomly selected student would be from either of the high schools so both high schools need to be taken into account.

The probability that a randomly selected student is satisfied with his or her school's variety of extracurricular activities can be calculated as:

= Number of students from both high schools that are satisfied / Total number of students in both high schools

= 79 / 120

Let's take '____' as x

[tex]x \times 14.32 = 554.76 \\ x = \frac{554.76}{14.32} \\ x = \frac{554.76 \times 100}{14.32 \times 100} \\ x = \frac{55476}{1432} \\ x = 38.74[/tex]

⎆ The answer of ____ x 14.32 = 554.76 in 2 decimal places will be ⇻38.74

Answer:

The nth term is 27 - 30(n-1) or can be simplified to 57 - 30n.

Step-by-step explanation:

This is an arithmetic sequence (ie. each term equals the previous term with a constant value added (or subtracted from it)

T1 = 27

T2 = -3 = T1 - 30 = 27 - 30

T3 = -33 = T2 -30 = 27 -30 - 30=27-30X(2)

T4= -63 = T3 - 30 =27-30X(2)-30=27-30X(3)

In general, the nth term of this sequence:

X - coordinate of preimage = 4

Translation, x coordinate + (-6)

Y - coordinate of preimage = - 3

Translation, x coordinate + (-8)

Image will be located at (4+(-6) ; - 3+(-8))
