The rental of the ice is $75, plus $3 per skater. Write an expression for the cost in dollars for n skaters.

Answer:

Step-by-step explanation:

I chose the first one. To compare the two products and find the better buy, let's find the cost of 1 ounce of cereal in each box. The unit rate for the left box will be $2.15 / 14 = $0.15 per ounce. The unit rate for the right box will be $3.40 / 20 = $0.17 per ounce. Because 0.15 < 0.17, the box on the left is the better buy. Hope this helps!

Answer:

2.15/14=0.153

3.4/20=0.17

Option A. is better because the price is smaller

4.50/3=1.5

5.96/4=1.49

option b is better

2.41/4=0.6025

1.8/2=0.9

option b is better

exact form: log(1024)

decimal form : 3.01029995

Step-by-step explanation:

Answer:

Step-by-step explanation:

two-thirds = 2/3 = 0.67

We would set up the hypothesis test.

For the null hypothesis,

p = 0.67

For the alternative hypothesis,

p < 0.67

This is a left tailed test.

Considering the population proportion, probability of success, p = 0.67

q = probability of failure = 1 - p

q = 1 - 0.67 = 0.33

Considering the sample,

Sample proportion, P = x/n

Where

x = number of success = 1312

n = number of samples = 2186

P = 1312/2186 = 0.6

We would determine the test statistic which is the z score

z = (P - p)/√pq/n

z = (0.6 - 0.67)/√(0.67 × 0.33)/2186 = - 6.96

From the normal distribution table, the probability value corresponding to the z score is < 0.00001

Since alpha, 0.01 > than the p value, then we would reject the null hypothesis. Therefore, at 1% significance level, there is convincing evidence that fewer than two-thirds of hiring managers and HR professionals use social networking sites in this way.

The values are [tex]x=2\sqrt{2}[/tex] and [tex]y=2\sqrt{6}[/tex].

Step-by-step explanation:

A right triangle is a type of triangle that has one angle that measures 90°.

In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse.

                                             [tex]\sin(\theta)=\frac{opposite \:site}{hypotenuse}[/tex]

To find the value of x we use the above definition. From the diagram we can see that the angle is 30º and the hypotenuse is [tex]4\sqrt{2}[/tex]. Therefore,

[tex]\sin(30)=\frac{x}{4\sqrt{2} }\\\\\frac{x}{4\sqrt{2}}=\sin \left(30^{\circ \:}\right)\\\\\frac{8x}{4\sqrt{2}}=8\sin \left(30^{\circ \:}\right)\\\\\sqrt{2}x=4\\\\\frac{\sqrt{2}x}{\sqrt{2}}=\frac{4}{\sqrt{2}}\\\\x=2\sqrt{2}[/tex]

To find the value of y we use the above definition. From the diagram we can see that the angle is 60º and the hypotenuse is [tex]4\sqrt{2}[/tex]. Therefore,

[tex]\sin(60)=\frac{y}{4\sqrt{2} }\\\\\frac{y}{4\sqrt{2}}=\sin \left(60^{\circ \:}\right)\\\\\frac{8y}{4\sqrt{2}}=8\sin \left(60^{\circ \:}\right)\\\\\sqrt{2}y=4\sqrt{3}\\\\\frac{\sqrt{2}y}{\sqrt{2}}=\frac{4\sqrt{3}}{\sqrt{2}}\\\\y=2\sqrt{6}[/tex]

Answer

8.41025641026

When you do long division that comes out to be your answer.

In slope-intercept form, we can classify the following values.

m = slope

b = y-intercept

Turn the equation into slope-intercept form (y = mx + b).

3y + 2x = -21

~Subtract 2x to both sides

3y + 2x - 2x = -21 - 2x

~Simplify

3y = -21 - 2x

~Divide 3 to both sides

3y/3 = -21/3 - 2/3x

~Simplify

y = -7 - 2/3x

~Put into correct order

y = -2/3x - 7

So, the y-intercept is -7

Best of Luck!

Answer: -7

Step-by-step explanation: To identify the y-intercept of the line, we would first convert the equation to slope-intercept form.

In slope-intercept form or y = mx + b form, the y

is by itself on the left side of the equation.

So our first task in this problem is to get y by itself on the left side of the equation and we do that by first subtracting 2x from both sides to get 3y = -2x - 21.

Notice that I put the x term first on the right side of the equation and then the number because in y = mx + b form, the x term comes first on the right side of the equation.

Continuing on, to get y by itself we would

divide both sides by 3 to get y = -2/3x - 7.

Now our equation is written in slope-intercept form and

we can identity that the y-intercept of this line is -7.

Answer:

[tex]t=\frac{(73.5-69.3)-0}{\sqrt{\frac{10.2^2}{16}+\frac{8.7^2}{12}}}}=1.173[/tex]  

Using the critical value method we need to find a critical value in the t distribution who accumulates 0.025 of the area on the right and we got:

[tex] t_{cric}= 2.06[/tex]

So then since our calculated value is lower then the critical value we fail to reject the null hypothesis and we can't conclude that the true mean resting pulse rate of people who do not exercise regularly is larger than the mean resting pulse rate of people who exercise regularly.

Step-by-step explanation:

Information given

[tex]\bar X_{1}=73.5[/tex] represent the mean for sample of people who do not exercise

[tex]\bar X_{2}=69.3[/tex] represent the mean for sample of people who do exercise

[tex]s_{1}=10.2[/tex] represent the sample standard deviation for 1  

[tex]s_{2}=8.7[/tex] represent the sample standard deviation for 2  

[tex]n_{1}=16[/tex] sample size for the group 1

[tex]n_{2}=12[/tex] sample size for the group 2

[tex]\alpha=0.01[/tex] Significance level

t would represent the statistic

System of hypothesis

We want to verify if the mean resting pulse rate of people who do not exercise regularly is larger than the mean resting pulse rate of people who exercise regularly, the system of hypothesis would be:  

Null hypothesis:[tex]\mu_{1}-\mu_{2} \leq 0[/tex]  

Alternative hypothesis:[tex]\mu_{1} - \mu_{2}> 0[/tex]  

The statistic for this case would be given by:

[tex]t=\frac{(\bar X_{1}-\bar X_{2})-\Delta}{\sqrt{\frac{s^2_{1}}{n_{1}}+\frac{s^2_{2}}{n_{2}}}}[/tex] (1)  

The degrees of freedom are given by:

[tex]df=n_1 +n_2 -2=16+12-2=26[/tex]  

Replacing the info given we got:

[tex]t=\frac{(73.5-69.3)-0}{\sqrt{\frac{10.2^2}{16}+\frac{8.7^2}{12}}}}=1.173[/tex]  

Using the critical value method we need to find a critical value in the t distribution who accumulates 0.025 of the area on the right and we got:

[tex] t_{cric}= 2.06[/tex]

Net price = $385.28

Step-by-step explanation:

Trade Discount - It is the discount given by buyer to seller, as a reduction in list price, when huge (bulk) orders transactions are made.

List price = 481.60

Trade Discount = 20%

So, Trade Discount = 20 / 100 (481.60) = 96.32

Net price = List price - Trade Discount = 481.60 - 96.32 = 385.28

Answer: S = 20 lbs L = 45 lbs.  Both answer have been rounded from below

Step-by-step explanation:

L+S = 65 lbs

55L + 65S = 3774 lbs

55L+55S = (65)(55) = 3,575 lbs

10S = 199 lbs

S = 19.99 (round to 20)

L + S = 65

L + 19.99 = 65

L = 45.01 (round to 45)

Answer:

The volume of air that can be hold is 267.9 inches³.

Step-by-step explanation:

Given that the volume of sphere formula is V = 4/3×π×r³ where r represents radius of sphere. Then substitute the values :

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

Let π = 3.14,

Let r = 4,

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

[tex]v = \frac{4}{3} \times 200.96[/tex]

[tex]v = 267.9 \: {inches}^{3} (near.tenth)[/tex]

The soccer can hold air up to the  volume of 267.9 cubic inches.

The measure of the capacity that an object holds is called volume.

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

Where, v is the volume of sphere

r is the radius of sphere

π = 3.14

According to the given question

The radius of soccer is 4 inches.

Therefore,

The volume of the soccer = [tex]\frac{4}{3}\pi (4)^{3}[/tex]            (shape of soccer is spherical)

Volume of soccer = [tex]\frac{4}{3} (3.14)(64)[/tex] [tex]= 267.946 cubic inches[/tex]

Hence, the soccer can hold air up to the  volume of 267.9 cubic inches.
