A certain granola bar has 2 grams of fiber. This is 8% of the recommended daily value. How many grams of fiber are recommended d

xeze [42]

If you formulate the question into a word equation it comes out:

2 grams fiber = .08 × DRV
↑ ↑ ↑ ↑ ↑
2 g fiber is 8% of the daily recommended value.

Now solve for DRV to find the daily recommended value:

2 g fiber/.08 = DRV

DRV = 25 g fiber

According to a survey of adults, 64 percent have money in a bank savings account. If we were to survey 50 randomly selected adul

zheka24 [161]

Answer:

The mean number of adults who would have bank savings accounts is 32.

Step-by-step explanation:

For each adult surveyed, there are only two possible outcomes. Either they have bank savings accounts, or they do not. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$

In this problem, we have that:

$p = 0.64$

If we were to survey 50 randomly selected adults, find the mean number of adults who would have bank savings accounts.

This is E(X) when $n = 50$ .

$E(X) = np = 50*0.64 = 32$

The mean number of adults who would have bank savings accounts is 32.

Which value represents the horizontal translation from the graph of the parent function f(x) = x^2 to the graph of the function

Vsevolod [243]

Translation by h (right) and k (up)
g(x)=f(x-h)+k
=f(x-4)^2+2
so h=4, k=2
horizontal translation (to the right) is h=+4, but is shown as -4 for the translation value.
