Answer:

5/21

Step-by-step explanation:

Here is a strategy I want you to remember: <u>Keep, Change, Flip</u>. What do I mean by that? Well...

Keep the first fraction. Change the division sign into a multiplication sign. Make the numerator of the second fraction become the denominator--and make the denominator of the second fraction become the numerator.

The denominator of any whole number is always 1. So, 7 equals to 7/1. Time to find the reciprocal of 7/1! What does reciprocal mean?

Reciprocal - <u>Flip the fraction in terms of the numerator and denominator</u>; <u>Multiplicative Inverse</u>

1/7 is the reciprocal of 7/1, for this mathematical problem. Makes sense, right?

Now, 5 times 1 equals 5 (that is the numerator). Secondly, 3 times 7 equals 21 (that is the denominator).

$\frac{5}{3} * \frac{1}{7} = \frac{5}{21}$

Answer:

Step-by-step Turn 7 into a fraction

3/5 ÷ 7/1

Use the recipricle and multiply

3/5 x 1/7

Multiply across

3/35

And that's it! :)

Can someone please explain?

<h2>Hello!</h2>

The answer is:

The correct option is the first option:

$y=-4x+64$

To write the equation of the line in slope-interception form we need to extract all the information that we need from the graphic.

We must remember that the slope-interception form of the lines is:

$y=mx+b$

Where,

y, is the function

m, is the slope of the line

x, is the variable

b, is the y-axis intercept

We can find the slope using the following formula:

$m=\frac{ChangeInY}{ChangeInX}$

Which is for this case:

$m=\frac{64}{16}=4$

As we can see from the graphic, the line is decresing, so the sign of the slope "m" will be negative, so:

$m=-4$

We can find the value of "b" seeing where the line intercepts the y-axis.

As we can see it intercept the y-axis at: $y=64$

Then, now that we already know the value of "m" and "b", we can write the equation of the line:

$y=mx+b=-4x+64\\y=-4x+64$

So, the correct option is the first option:

$y=-4x+64$

Have a nice day!

ricardo purchased a bunk bed for his children fora sale price of $276.25. The sale price was 65% of the original price. Calculat

nikklg [1K]

Use the formula S=P-PD

S is sale price, original price is P, and PD is discounted percent,

276.25=P-P(.65), I turned the percent into a decimal.

276.25=P(1-.65)

276.25=P(.35)

Now cross multiply.

$\frac{276.26}{.35}=\frac{P(.35)}{.35}\\\\P=\frac{276.26}{.35}=789.31$

Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)

The average number of employees that call in sick for the day over the course of a year is 25.

Answer:

Step-by-step explanation:

The mean of a set of numbers is the sum divided by the number of terms.

x¯= <u>25+10+16+39+27+25+32+25+25+22+28+14</u>

<h3>Simplify the numerator. </h3>

x¯ = <u>261.27</u>

<h3>Divide 261.27 by 11 </h3>

x¯= 23.75 18

<h3>Divide. </h3>

x¯= 23.75 18

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

x¯=23.8

<h3>Simplify each value in the list. </h3>

25,10,16,39.27,25,32,25,25,22,28,14

Set up the formula for sample standard deviation. The standard deviation of a set of values is a measure of the spread of its values.

s= n^∑ i=1 √(<u>xi−xavg</u>)²

N-1

Set up the formula for standard deviation for this set of numbers.

s= ⎷(25−23.8)²+(10−23.8)²+(16−23.8)²+(39.27−23.8)²+(25−23.8)²+<u>(32−23.8)²+(25−23.8)²+(25−23.8)²+(22−23.8)²+(28−23.8)²+(14−23.8)</u>²

11−1

<h3>Simplify the result. </h3>

s= √68.05209

The standard deviation should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

The recursive function for a sequence is given below.

masya89 [10]

Answer:

f(5) = 3200

Step-by-step explanation:

Using the recursive formula to generate the terms, that is

f(2) = 2 × f(1) = 2 × 200 = 400

f(3) = 2 × f(2) = 2 × 400 = 800

f(4) = 2 × f(3) = 2 × 800 = 1600

f(5) = 2 × f(4) = 2 × 1600 = 3200
