Answer:

130

Step-by-step explanation:

Number of students old donors can be calculated from the Pareto chart by adding number of blood donors on the different bars:

Type 0= 50

Type A= 35

Type B =30

Type AB =15

Therefore 50+35+30+15=130 blood donors

F(x)=9÷4x-15 for x=4

enyata [817]

9/4x -15 for x=4

To find this answer you must plug the 4 everywhere the x is located.

(9/4)(4) -15

Multiply 9/4 by 4

(9/4) x 4 = 9

Now we take our 9 answer and add it to -15.

9-15 = -6

The answer is -6

For the other equation, you also must plug in 3 where ever x is located in the equation.

5/3x -3/5

(5/3)(3) -3/5

Multiply 5/3 and 3

(5/3) x 3 = 5

Take that answer of 5 and add -3/5

5- (3/5) =4 2/5

The answer to this equation would be 4 2/5 or 4.4

The points , (−15,1) and , (−7,r) lie on a line with slope 5/4. Find the missing coordinate r. Click image to enlarge

Nadya [2.5K]

The missing coordinate r is 11.

Solution:

Given points are (–15, 1) and (–7, r).

$x_{1}=-15, x_{2}=-7, y_{1}=1 \text { and } y_{2}=7$

Slope (m) = $\frac{5}{4}$

<u>To find the missing coordinate r:</u>

Slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute the given values in the formula.

$$\frac{5}{4}=\frac{r-1}{-7-(-15)}$

$$\frac{5}{4}=\frac{r-1}{-7+15}$

$$\frac{5}{4}=\frac{r-1}{8}$

Do cross multiplication.

$8 \times 5=4(r-1)$

40 = 4r – 4

Add 4 on both side of the equation.

44 = 4r

Divide by 4 on both side of the equation.

11 = r

⇒ r = 11

Hence the missing coordinate r is 11.
