There were 60 runners to start the race. In the first half of the race,1/3 of them dropped out. In the second half of the race,1

Verizon [17]

In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
   = 20
Number of runners remaining = 60 - 20
   = 40
Number of runners dropping out in the second half = 40 * 1/4
   = 10
Then the number of runners that finished the race = 40 - 10
   = 30
Then 30 runners completed the race.

For the data shown in the scatter plot, which is the best estimate of r? A. 0.95 B. −0.55 C. 0.55 D. −0.95

astra-53 [7]

Answer:

C. 0.55

Step-by-step explanation:

The scatter plot shows that there is a positive correlation between variable x and variable y. This is because, the x and y variable seem to follow the same trend. That is, as x variable increases, y variable also increases. If a line of best fit is drawn, it would slope upwards, from left to our right.

Correlation coefficient (r) of any given data set plotted on a scatter plot, ranges from -1 to 1. The closer the value of "r" to either -1 or 1, the more clustered the data points are together in a line of best fit in a scatter plot.

Therefore, since the scatter plot given shows a positive relation between the x and y variables, whereby the data points seem to be less clustered and farther from each away from the line if best fit, if drawn, an estimate of "r" would not be closer to the value of 1.

Therefore, from the options given, C. 0.55 is the best estimate for r for the data shown in the scatter plot.

The volume of a rectangular prism is found by multiplying the length, width, and height of the prism. A rectangular prism has a

Readme [11.4K]

Answer:

<h2>V = 70x⁹ cubic units</h2>

Step-by-step explanation:

The formula of a volume of a rectangular prism:

$V=lwh$

l - length

w - width

h - height

We have:

$l=7x^3,\ w=5x^2,\ h=2x^4$

Substitute:

$V=(7x^3)(5x^2)(2x^4)=(7\cdot5\cdot2)(x^3x^2x^4)=70x^{3+2+4}=70x^9$

Used

$a^n\cdot a^m=a^{n+m}$

MA_775_DIABLO [31]

<h2>Question</h2>

Simplify the following

A . ( 12 ) x ( − 16 ) + 16

b . ( − 34 ) ÷ ( − 23 ) + 14

c . ( − 45 ) ÷ ( − 15 ) + 13

d . ( 23 ) - ( − 16 ) - 13

e . ( − 42 ) + ( - 16 ) ÷ 13

<h2>Answer:</h2>

(A) -176

(B) $\frac{402}{23}$

(D) 26

(E) $\frac{-562}{13}$

<h2>Step-by-step explanation:</h2>

(A)

( 12 ) x ( − 16 ) + 16

Following the rules of BODMAS

<em>=> Solve the brackets first</em>

12 x -16 + 16

<em>=> Next, solve the multiplication(x)</em>

-192 + 16

<em>=> Solve the addition and subtraction</em>

-176

(B)

( − 34 ) ÷ ( − 23 ) + 14

Following the rules of BODMAS

<em>=> Solve the brackets first</em>

-34 ÷ -23 + 14

<em>=> Next, solve the division(÷)</em>

$\frac{-34}{-23}$ + 16

The negative signs can cancel out.

$\frac{34}{23}$ + 16

<em>=> Solve the fraction</em>

$\frac{34}{23}$ + $\frac{16}{1}$

$\frac{34 + 368}{23}$

$\frac{402}{23}$

(C)

( − 45 ) ÷ ( − 15 ) + 13

Following the rules of BODMAS

<em>=> Solve the brackets first</em>

-45 ÷ -15 + 13

<em>=> Next, solve the division(÷)</em>

$\frac{-45}{-15}$ + 13

The negative signs can cancel out.

$\frac{45}{15}$ + 13

3 + 13

<em>=> Solve the addition</em>

3 + 13 = 16

(D)

( 23 ) - ( − 16 ) - 13

Following the rules of BODMAS

<em>=> Solve the brackets first</em>

23 - -16 - 13

23 + 16 - 13

<em>=> Next solve the addition</em>

39 - 13

<em>=> Next solve the subtraction</em>

39 -13 = 26

(E)

( − 42 ) + ( - 16 ) ÷ 13

Following the rules of BODMAS

<em>=> Solve the brackets first</em>

-42 + -16 ÷ 13

-42 - 16 ÷ 13

<em>=> Next solve the division</em>

-42 - 16 ÷ 13

-42 - $\frac{16}{13}$

<em>=> Next solve the fraction</em>

$\frac{-42}{1}$ - $\frac{16}{13}$

$\frac{-546-16}{13}$

$\frac{-562}{13}$
