Consider the probability that at least 93 out of 154 CDs will not be defective. Assume the probability that a given CD will not

Yuki888 [10]

Answer:

0.5962

Step-by-step explanation:

Given that :

p = 61% = 0.61

q = 1 - p = 1 - 0.61 = 0.39

n = 154 ; x = 93

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x>=93) = p(x=93)+p(x=94)+...+p(x=n)

P(x>= 93) = 0.59619

P(x>= 93) = 0.5962

a 10 foot ladder is leaning against the wall. the bottom of the ladder is 4ft from the base of the wall. which of the following

Pie

Answer:

The height of the wall is 9.17ft

Step-by-step explanation:

The length of the ladder is 10ft

Distance from the foot of the ladder to the wall is 4ft

The height of ladder is unknown.

To solve this question, you'll require a pictorial illustration of the situation. Kindly check attached document for that.

Since it's a right angle triangle, we have two sides with one sides unknown, we can use pythagorean theorem to find the third side.

The hypothenus (x) is 10ft

The adjacent is (y) 4 ft

The opposite (z) (height of the wall) is unknown.

X² = Y² + Z²

10² = 4² + Z²

100 = 16 + Z²

Z² = 100 - 16

Z² = 84

Z = √(84)

Z = 9.165 = 9.17ft

The height of the wall is 9.17ft

Round your answer to the nearest hundredth. A flower garden is 11.25 meters long. Mr. Owens wants to make a border along one si

vaieri [72.5K]

To find the answer just divide the length of a flower garden by the length of a brick:

11.25 / 0.25 = 45 (that's how many bricks are needed to be put).

There's nothing to round, but you can write it as a decimal to the hundredth place as 45.00.

Suppose f(x) − f(x+1) = 3x^2 and f(3) = 48, determine the value of f(5) show all steps so i can understand how you got to the an

Anettt [7]

Step-by-step explanation:

f(3) = 48

f(3)-f(4) = 3*3^2

f(4) = 21

f(4)-f(5) = 3*4^2

f(5) = -27

When a gas is kept at a constant temperature and pressure on it changes, its volume changes according to the following formula,

astra-53 [7]

Answer: Approximately 1.9 atm

============================================

Work Shown:

$P_1*V_1 = P_2*V_2 \ \text{ ... Boyle's Law}\\\\4.5*1.5 = P_2*3.5\\\\6.75 = P_2*3.5\\\\P_2*3.5 = 6.75\\\\P_2 = \frac{6.75}{3.5}\\\\P_2 \approx 1.92857142857142\\\\P_2 \approx 1.9\\\\$

If the volume is 3.5 liters, then the pressure is approximately 1.9 atm.

Note the increase in volume leads to the reduction of pressure, and vice versa. The two variables have an inverse relationship.

-----------

As a check,

$P_1*V_1 = P_2*V_2\\\\4.5*1.5 \approx 1.9*3.5\\\\6.75 \approx 6.65\\\\$

We don't get the exact thing on both sides, but the two sides are close enough. We have rounding error due to P2 being not exact.

A more accurate check could be

$P_1*V_1 = P_2*V_2\\\\4.5*1.5 \approx 1.92857*3.5\\\\6.75 \approx 6.749995\\\\$

which has the two sides much closer to one another. This helps us verify the answer.
