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

Pie charts can generally be used instead of bar graphs

Step-by-step explanation:

A pie chart can be used instead of a bar chart. A pie chart is an alternative to the bar chart. Both of these can be regarded as data visualization tools. The pie chart shoes us generally how several parts makes up a whole. While the bar chart uses rectangular bars to show us the proportion of each of the categories of data

The statement which is true among the given group of options is; Pie charts can generally be used instead of bar charts.

Pie charts can be used as substitutes for bar charts. This stemmed from.the fact that both tools are data visualization tools.

On this note, pie charts can be used to replace the bar charts even though pie charts entails dividing the 360° angle in a circle in respective ratios.

Answer:

ig 10?

Step-by-step explanation:

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.".

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:

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:

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

Step-by-step explanation:

Step 1: Define Systems

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
