Yes, 50% of $200 i’d $100 so the shoes and the knee pads combined are $90. Which is below the 50% mark.

Answer:

Yes

Step-by-step explanation:

First, we need to know what 50% of 200 is. Well, 50% basically is just another way to say half of.

So, what is half of 200?

Well, if we split 200 into 2 equal parts, we get 100, so 100 is half of 200.

So, we know that James wants to spend less than $100 on skateboarding shoes and knee pads.

To find out if he can spend less than 100 dollars, we have to add up the prices of the shoes and knee pads, and see if it is less than 100.

Knee pads cost $30

Shoes cost $60

So, we add the price of $60 to the price of $30

30 + 60 = 90

That means it costs $90 to buy shoes and knee pads

90 is less than 100, so he is able to spend less than 50% of his savings on skateboarding shoes and knee pads.

jonny [76]

Answer:

Pr(X >42) = Pr( Z > -2.344)

                = Pr( Z< 2.344) = 0.9905

Step-by-step explanation:

The scenario presented can be modeled by a binomial model;

The probability of success is, p = 0.65

There are n = 80 independent trials

Let X denote the number of drivers that wear a seat belt, then we are to find the probability that X is greater than 42;

Pr(X > 42)

In this case we can use the normal approximation to the binomial model;

mu = n*p = 80(0.65) = 52

sigma^2 = n*p*(1-p) = 18.2

Pr(X >42) = Pr( Z > -2.344)

                = Pr( Z< 2.344) = 0.9905
