n200080 [17]

Answer:

0.1527

Step-by-step explanation:

Given that a researcher wishes to conduct a study of the color preferences of new car buyers.

Suppose that 50% of this population prefers the color red

15 buyers are randomly selected

Let X be the no of buyers who prefer red.

X has exactly two outcomes red or non red.

Also each buyer is independent of the other

Hence X is binomial with p = 0.5 and n = 15

Required prob =The probability that exactly three-fifths of the buyers would prefer red

= P(X=9)

= $15C9 (0.9)^9 (0.6)^6$

= $5005(0.0000305)=0.1527$

1.3n-0.03=-9 (solve for n) grade lvl. 7

bazaltina [42]

Hello from MrBillDoesMath!

Answer:

-6.9

Discussion:

1.3n - 0.03 = -9 => multiply both sides by 100

130n - 3 = -900 =>

130n = -900 +3 = -897 => add 3 to both sides

n = -897/130 =>

n = - (69 * 13)/ (10*13) =>

n = - 69/10 = - 6.9

Thank you,

Explain how to find the surface area of a can of fruit with a height of 80 mm and a diameter of 60 mm. Give the area in your exp

8_murik_8 [283]

Answer:

$S=6600\pi \text{ mm}^2$

$S\approx 20724 \text{ mm}^2$

Step-by-step explanation:

A can of fruit is geometrically a cylinder.

We are talking about the <u>surface area of a cylinder</u>:

$S=2\pi rh+2\pi r^2$

$\pi \approx 3.14$

$r: \text{radius}$

$h: \text{height}$

Factoring, we have:

$S=2\pi r (h+r)$

Calculating the surface area of the can of fruit:

$S=2\pi (30) (80+30)$

$S=2\pi (30) (110)$

$S=6600\pi$

$S\approx 20724 \text{ mm}^2$

Camille is packing moving boxes. She has one 4 cubic-foot box and one 7 cubic-foot box. How many cubic feet of clothing can she

adell [148]

Answer:

He can fit 11 ft^3

Step-by-step explanation:

Here, we want to get the volume it clothes that could fit into the two boxes

What we have to do here is to add the amount of space each of the box has to offer

Mathematically, we have this as;

7 ft^3 + 4 ft^3 = 11 ft^3
