Answer:

d

Step-by-step explanation:

Given:

The numbers are 160, 192, 240​.

To find:

The LCM of 160, 192, 240.

Solution:

The given numbers are  160, 192, 240​. Write the factor forms of these numbers.

[tex]160=2\times 2\times 2\times 2\times 2\times 5[/tex]

[tex]160=2^5\times 5[/tex]

[tex]192=2\times 2\times 2\times 2\times 2\times 2\times 3[/tex]

[tex]192=2^6\times 3[/tex]

[tex]240=2\times 2\times 2\times 2\times 3\times 5[/tex]

[tex]240=2^4\times 3\times 5[/tex]

Now, the LCM of given numbers is the product of all prime factors with highest degrees.

[tex]LCM=2^6\times 3\times 5[/tex]

[tex]LCM=64\times 15[/tex]

[tex]LCM=960[/tex]

Therefore, the LCM of given numbers is 960.

Answer:

D

Step-by-step explanation:

The answer is the side opposite /  hypotenuse.

Definitions

The side opposite is the side which is not connected directly with angle (A). So it is the line that is 24 units long.

The hypotenuse is the longest line of a right triangle. It is opposite the right angle. It is 30 in this case.

Answer:

2x-7=(x+10)/2

2(2x-7)=x+10

4x-14=x+10

4x-x=10+14

3x=24

x=24/3

x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

The midsegment is half of GI , that is

2x - 7 = [tex]\frac{1}{2}[/tex] (x + 10) ← multiply both sides by 2 to clear the fraction

4x - 14 = x + 10 ( subtract x from both sides )

3x - 14 = 10 ( add 14 to both sides )

3x = 24 ( divide both sides by 3 )

x = 8

Answer:

The interest generated the first year will be 10% of the principal value, while the second year said interest will be 10.25%.

Step-by-step explanation:

Given that a person deposits Rs 55000 in Bank P for 2 years at the rate of 10% per annum compounded annually, but after one year, bank has changed the policy and decided to pay semi annual compounded interest at the same rate, to determine what is the percentage difference between the compound interests of the first year and second year, the following calculation must be performed:

Year 1 =

55,000 x (1 + 0.1 / 1) ^ 1x1 = X

55,000 x 1.1 = X

60,500

Year 2 =

60,500 x (1 + 0.1 / 2) ^ 1x2 = X

60,500 x 1.05 ^ 2 = X

66,701.25 = X

55,000 = 100

60,500 = X

60,500 x 100 / 55,000 = X

110 = X

60,500 = 100

66,701.25 = X

66,701.25 x 100 / 60,500 = X

110.25 = X

Therefore, the interest generated the first year will be 10% of the principal value, while the second year said interest will be 10.25%.

Answer:

[tex]\frac{95}{56}[/tex] or [tex]1\frac{39}{56}[/tex]

Step-by-step explanation:

hope this helps have a good day :)

Answer:

Decimal Answer: 1.7

Fraction Answer: 1 39/56

Answer:

a)

The null hypothesis is [tex]H_0: p = 0.91[/tex].

The alternate hypothesis is [tex]H_1: p < 0.91[/tex].

The decision rule is: accept the null hypothesis for [tex]z > -1.645[/tex], reject the null hypothesis for [tex]z < -1.645[/tex].

Since [tex]z = -1.79 < -1.645[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.

b)

The p-value for this test is 0.0367. Since this p-value is less than the significance level of [tex]\alpha = 0.05[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.

Step-by-step explanation:

Question a:

Perform the appropriate hypothesis test to determine whether this is significant evidence that the percentage of athletes who graduate is less than for the student population at large:

At the null hypothesis, we test if the proportion is the same as the student population, of 91%. Thus:

[tex]H_0: p = 0.91[/tex]

At the alternate hypothesis, we test that the proportion for athletes is less than 91%, that is:

[tex]H_1: p < 0.91[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

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

Test if the proportion is less at the 0.05 level:

The critical value is z with a p-value of 0.05, that is, z = -1.645. Thus, the decision rule is: accept the null hypothesis for [tex]z > -1.645[/tex], reject the null hypothesis for [tex]z < -1.645[/tex].

0.91 is tested at the null hypothesis:

This means that [tex]\mu = 0.91, \sigma = \sqrt{0.91*0.09}[/tex]

A sports reporter contacted 152 athletes randomly sampled from that same university and time period and found that 132 of them had graduated within 6 years.

This means that [tex]n = 152, X = \frac{132}{152} = 0.8684[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.8684 - 0.91}{\frac{\sqrt{0.91*0.09}}{\sqrt{152}}}[/tex]

[tex]z = -1.79[/tex]

Since [tex]z = -1.79 < -1.645[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.

(b) (3 points) Calculate the P-value for this test. Explain how this P-value can be use to test the hypotheses in part (a).

The p-value of the test is the probability of finding a sample proportion of 0.8684 or below. This is the p-value of z = -1.79.

Looking a the z-table, z = -1.79 has a p-value of 0.0367.

The p-value for this test is 0.0367. Since this p-value is less than the significance level of [tex]\alpha = 0.05[/tex], we reject the null hypothesis and accept the alternate hypothesis that that percentage of athletes who graduate is less than for the student population at large.

Answer:

and the question is...

Step-by-step explanation:

[tex]v = \frac{4}{3} \times \pi \times {r}^{3} [/tex]

Finding the radius,

[tex]d = 2r, \: r = \frac{d}{2} = \frac{8}{2} = 4inches[/tex]

Plugging in our values,

[tex]v = \frac{4}{3} \times 3.14 \times {4}^{3} = \frac{4}{3} \times 3.14 \times 64 = 267.95 {inches}^{3} \\ [/tex]

Rounding to the nearest whol number,

[tex]v = 268 {inches}^{3} [/tex]

Answer:

Make x the same in both so

12x+ 4y=72

12x+6y=30

Now the 12x cancel eachother out so

Difference between 6y and 4y is 2y

Difference between 30 and 72 is -42

2y must equal -42

Y = -21

Substitute -21 into the equation

X = 13
