Answer: S = 221

Step-by-step explanation: An arithmetic sequence is a set of numbers in order, having the difference between one term and the next a constant.

The sum of an arithmetic sequence can be calculated as the following formula:

[tex]S=\frac{n}{2} [2a_{1}+(n-1)r][/tex]

where

n is how many terms to add

a₁ is the 1st term of the sequence

r is the constant

For the sequence above:

[tex]S=\frac{17}{2} [2(5)+(17-1)1][/tex]

[tex]S=\frac{17}{2}(26)[/tex]

[tex]S=17(13)[/tex]

S = 221

The sum of the first 17 terms of the arithmetic sequence {5,6,7,8,9,10...} is 221

Answer:

They spent 112 dollars on props.

The required total 16% spend on the props is $112.

Given that,
A group of friends was working on a student film that had a budget of $700. They used 16% of their budget on props. How much money did they spend on props is to be determined.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

A group of friends was working on a student film that had a budget of $700.
Budget = $700
They used 16% of their budget on props.
Total spend on the props = 700 * 16 / 100
                                       = $ 112

Thus, the required total 16% spend on the props is $112.

Step-by-step explanation:

From the chart given, it shows that the number of makes that chose bike riding as their favorite activity are 10.

Females who chose bike riding activity are 9.

The difference between number of makes and number of makes and females who chose bike riding = 10 - 9 = 1

Therefore, this means that 1 more male than the female chose bike riding.

Answer:

The margin of error for a 99% confidence interval. is of $2.25.

Step-by-step explanation:

We have the sample's variance, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 600 - 1 = 599

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 600 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.84.

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

In which s is the standard deviation of the sample(square root of the variance) and n is the size of the sample.

In this question:

[tex]s = \sqrt{375}, n = 600[/tex]. So, the margin of error is of:

[tex]M = 2.84\frac{\sqrt{375}}{\sqrt{600}} = 2.25[/tex]

The margin of error for a 99% confidence interval. is of $2.25.

y = 2x + 7

y = x + 8

Step 2: Solve for x

Substitution

Step 3: Solve for y

Answer:

x = 1

y = 9

Step-by-step explanation:

y = 2x + 7 --------------------(I)

y = x + 8 ----------------------(II)

Substitute y = 2x + 7 in equation (I)

    2x + 7 = x + 8           {Subtract 'x' from both sides}

2x + 7 - x = 8                 {Combine like terms}

      x + 7 = 8                  {Subtract 7 from both sides}

           x  = 8 -7

x = 1

Substitute x = 1 in equation (I)

y = 2*1 + 7

 = 2 + 7

y = 9

Answer:

x = 4

Step-by-step explanation:

Using cosine triangle formula, we know that;

c² = a² + b² - 2ac(cos C)

From our diagram;

a = 2x

b = x + 1

c = 7

C = 60°

Thus;

7² = (2x)² + (x + 1)² - 2(2x)(x + 1)cos 60

49 = 4x² + (x² + 2x + 1) - (4x² + 4x)(0.5)

49 = 5x² + 2x + 1 - 2x² - 2x

3x² + 1 - 49 = 0

3x² - 48 = 0

3x² = 48

x² = 48/3

x² = 16

x = √16

x = 4

The rate paid per hour for the given condition will be $7.89 per hour thus option (D) is correct.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

As per the given,

Total paid = $157.80

Total hours working = 20 hours

Rate of change = 157.80/20 = $7.89 per hour

Hence "The hourly wage for the specified circumstance will be $7.89.".

Answer:

M AED = 32.5º

Explanation:

M AED = 1/2 x (113º - 48º) = 32.5º

This is an example of angles with vertex outside the circle and their arcs. The formula to find the measure of an angle with the vertex outside the circle is 1/2 x (difference of intercepted arcs), in this case it's 1/2 x (113º - 48º), which equals 32.5º.

Answer:

85% of 40

Step-by-step explanation:

We can do this in two ways, we can either use percent proportions or use benchmark percentages. I'll do both.

So the equation for percent proportions will look something like this:

34/x = 40/100

So to solve this, we do 34*100/40, which is 3400/40 which equals 85. That means that 34 is 85% of 40 inches.

Another way to do this is to use benchmark percents:

10% of 40 is 4 and, so you do 40-4 and get 36. Then we need to get 2 more down so we do 5% of 40 which is 2, so we do 36-2 or 40-6.

Then we add up the percents which would add up to 15%, we do 100-15 and get 85%

Or we could just say, well 6 is 15% of 40 so we do 100-15 and 40-6 and get that 34 = 85% of 40
