Mathematics

ryzh [129]3 years ago
4 0

Answer:

x=-72

Step-by-step explanation:

The given equation is \sqrt[3]{x+8}=-4.

We cube both sides of this equation to obtain;

(\sqrt[3]{x+8})^3=(-4)^3.

This implies that;

(x+8)=-64

We group similar terms to obtain;

x=-64-8

We simplify the right hand side of the equation to obtain;

x=-72

Therefore x=-72 is the solution of the given equation.

Iteru [2.4K]
The answer is 3/8. You can find a common denominator of 64 among all of the fractions. From this, you can find how many orange candies there are. There is 64 candies, and 40 of them are other flavors, so there's 24 orange candies. You can create the fraction 24/64 and simplify it down to 3/8.

Assume that blood pressure readings are normally distributed with a mean of 124 and a standard deviation of 6.4. If 64 people ar
Murrr4er [49]

Answer:

99.38%

Step-by-step explanation:

We have that the mean (m) is equal to 124, the standard deviation (sd) 6.4 and the sample size (n) = 64

They ask us for P (x <126)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / (sd / (n ^ 1/2))

We have all these values, replacing we have:

z = (126 - 124) / (6.4 / (64 ^ 1/2))

z = 2.5

With the normal distribution table (attached), we have that at that value, the probability is:

P (z <2.5) = 0.9938

The probability is 99.38%
