Step-by-step explanation:

If Lucy got 5/6, we can do the following.

(5/6) * 180 = 150

So, Lucy got 150 votes.

Answer:

150

Step-by-step explanation:

We can first divide 180 by 6:

180/6 = 30

Then multiply that by 5:

5 × 30 = 150

Answer:

(a+2)(a+6)

Step-by-step explanation:

Given expression ,

=> a² + 8a + 12

=> a² + 6a + 2a + 12

=> a(a+6) + 2(a+6)

=> (a+2)(a+6)

Step-by-step explanation:

the numbers : x, y

x = y + 8

x + y = 22

we use the first equation in the second :

y + 8 + y = 22

2y + 8 = 22

2y = 14

y = 7

x = y + 8 = 7 + 8 = 15

The net pay is the amount left after taxes and deductions have been removed from the gross pay.

Her monthly gross pay is: $4111.93

The deductions are:

[tex]\mathbf{FIT = \$102}[/tex]

[tex]\mathbf{SIT = 3.2\%}[/tex]

[tex]\mathbf{CIT = 1.8\%}[/tex]

Let her gross pay be x.

So, we have:

[tex]\mathbf{Net = x - FIT - x \times SIT - x \times CIT}[/tex]

So, we have:

[tex]\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}[/tex]

Express percentage as decimals

[tex]\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}[/tex]

[tex]\mathbf{3804.33 = x - 102 - 0.032x - 0.018x}[/tex]

Add 102 to both sides

[tex]\mathbf{3906.33 = x - 0.032x - 0.018x}[/tex]

[tex]\mathbf{3906.33 = 0.95x}[/tex]

Divide both sides by 0.95

[tex]\mathbf{4111.93 = x}[/tex]

Rewrite as:

[tex]\mathbf{x = 4111.93 }[/tex]

Hence, her monthly gross pay is: $4111.93

Answer:

Step-by-step explanation:

Testing the hypothesis, we have that:

a)

The null hypothesis is: [tex]H_0: \mu = 128[/tex]

The alternative hypothesis is: [tex]H_1: \mu \neq 128[/tex]

b) The p-value of the test is of 0.1212.

c) Since the p-value of the test is of 0.1212 > 0.05, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

d) Since |z| = 1.55 < 1.96, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

Item a:

At the null hypothesis, we test if the mean is the same, that is, of 128 texts every day, hence:

[tex]H_0: \mu = 128[/tex]

At the alternative hypothesis, we test if the mean is different, that is, different of 128 texts every day, hence:

[tex]H_1: \mu \neq 128[/tex]

Item b:

We have the standard deviation for the population, thus, the z-distribution is used. The test statistic is given by:

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

The parameters are:

[tex]\overline{x}[/tex] is the sample mean.

[tex]\mu[/tex] is the value tested at the null hypothesis.

[tex]\sigma[/tex] is the standard deviation of the population.

n is the sample size.

For this problem, the values of the parameters are: [tex]\overline{x} = 118.6, \mu = 128, \sigma = 33.17, n = 30[/tex]

Hence, the value of the test statistic is:

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

[tex]z = \frac{118.6 - 128}{\frac{33.17}{\sqrt{30}}}[/tex]

[tex]z = -1.55[/tex]

Since we have a two-tailed test, as we are testing if the mean is different of a value, the p-value is P(|z| < 1.55), which is 2 multiplied by the p-value of z = -1.55.

Looking at the z-table, z = -1.55 has a p-value of 0.0606

2(0.0606) = 0.1212

The p-value of the test is of 0.1212.

Item c:

Since the p-value of the test is of 0.1212 > 0.05, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

Item d:

Using a z-distribution calculator, the critical value for a two-tailed test with 95% confidence level is |z| = 1.96.

Since |z| = 1.55 < 1.96, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

Answer:

For example, if you have to work out the original price of a laptop that is being sold at 25% off:

work out the current price as a percentage of the original price (100%): current price is 100% - 25%

Find 1% by dividing the current price by 75.

Multiply this 1% by 100 to find the original price (100%)

Step-by-step explanation:

Answer:

$42.25

Step-by-step explanation:

List price = $65.00

Discount = 35% .

Hence the new price is (100-35)% = 65% of original price .

=> price = $ 65 * 65/100

=> price = $42.25

Answer:

see below

Step-by-step explanation:

By def. of the derivative, we have for y = ln(x),

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac{\ln(x+h)-\ln(x)}{h}[/tex]

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac1h \ln\left(\frac{x+h}{x}\right)[/tex]

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \ln\left(1+\frac hx\right)^{\frac1h}[/tex]

Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as

[tex]\displaystyle \frac{dy}{dx} = \lim_{y\to0} \ln\left(1+y\right)^{\frac1{xy}}[/tex]

[tex]\displaystyle \frac{dy}{dx} = \frac1x \lim_{y\to0} \ln\left(1+y\right)^{\frac1y}[/tex]

Recall that the constant e is defined by the limit,

[tex]\displaystyle e = \lim_{y\to0} \left(1+y\right)^{\frac1y}[/tex]

Then in our limit, we end up with

[tex]\displaystyle \frac{dy}{dx} = \frac1x \ln(e) = \boxed{\frac1x}[/tex]

Answer:

x = 10

Step-by-step explanation:

to find the measure of angles we first need to find the value of x

The sum of interior angles in a triangle is equal to 180

9x + 7x + 2x = 180 add like terms

18x = 180 divide both sides by 18

x = 10 to find angle measures replace x with 10 in each representative like:
