Answer:

80 Ft²

Step-by-step explanation:

Area= length x width

length= 10 feet

width= 8 feet

A= 10 × 8

A= 80 Ft²

squared because it's feet multiplied by feet

Ft × Ft= Ft²

defon

Answer:

0.5015 = 50.15% probability that it came from manufacturer A.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Defective

Event B: From manufacturer A.

Probability a unit is defective:

2% of 43%(from manufacturer A)

1.5% of 57%(from manufacturer B). So

P(A) = 0.02*0.43 + 0.015*0.57 = 0.01715

Probability a unit is defective and from manufacturer A:

2% of 43%. So

P(A \cap B) = 0.02*0.43 = 0.0086

What is the probability that it came from manufacturer A?

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0086}{0.01715} = 0.5015

0.5015 = 50.15% probability that it came from manufacturer A.

If a angle is 4 times bigger than its supplement what will its measure be
Ne4ueva [31]
Supplementary angles mean that two angles equal to 180°.

Let us assume the 2 angles are angle A and angle B.

Angle A is 4 times bigger than Angle B, the supplement.

Let Angle B be represented by x.

Angle A is 4x ; Angle B is x.

4x + x = 180°
5x = 180°
x = 180°/5
x = 36°  This is the measure of angle B.

4x = 4(36°) = 144° This is the measure of angle A.

4x + x = 180°
144° + 36° = 180°
180° = 180°

#24, the wording of the question throws me off.
dedylja [7]
I believe that the question is asking if there is a large variation between the results or not, as it asks if the births are with equal frequency. Since the largest is 72 and the smallest is 43 (for a 29 number difference), it doesn't seem like they are with the same frequency
