The top graph is your answer.

Note that pink = cherry, and yellow = lemon. The question states that for every 4 cherry sold, one lemon is, therefore making the ratio 4 cherry: 1 lemon.

The next question is asking that how much in total is sold if there are 30 more cherry cones sold.

Let the amount of lemon cones sold be denoted by the variable, x.

The amount of cherry cones would still sold would be 4:1, but the amount is 30 more then x.

Multiply both sides of the ratio given by 10:

4 x 10 = 40

1 x 10 = 10

The result will give you 30 more cherry cones, and also give you the total of 50 cones in all.

50.

The perimeter of the rectangle playing field is 432 yards the length of the field is 4 yards less than triple the width The peri

seraphim [82]

Answer:

160 yards

Step-by-step explanation:

P=2l+2w

P=2(3w-8)+2(w)

432=2(3w-8)+2(w)

432=6w-16+2w

432=8w-16

432+16=8w

448=8w

w=448/8

w=56yards

l=3(56)-8

l=168-8=160yards

Suppose that out of 20% of all packages from Amazon are delivered by UPS. 15% of the packages that are delivered by UPS weighs 2

Gelneren [198K]

Answer:

0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more

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: It weighs 2 lbs or more

Event B: Delivered by UPS

15% of the packages that are delivered by UPS weighs 2 lbs or more.

This means that $P(A \cap B) = 0.15$

More than 2 lbs:

15% of 20%(UPS)

93% of 80%(Not delivered by UPS). So

$P(A) = 0.15*0.2 + 0.93*0.8 = 0.774$

a. What is the probability that a package is delivered by UPS if it weighs 2 lbs or more

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.15}{0.774} = 0.1938$

0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more
