How can multiplication be used to check your division equation answer?

Multiplication and division are opposites and can be used to undo each other.
For example,
4/2=2
But if you take the quotient and multiply it by the divisor
2x2=4
you get the original dividend

200% of X is 34. What is x?

ella [17]

Step-by-step explanation:

200% of x =34

$\frac{200}{100} \times x = 34$

$2 \times x = 34$

$2x = 34$

$divide \: both \: sides \: by \: 2$

$\frac{2x}{2} = \frac{34}{2}$

$x = 17$

Aisha wants to advertise how many chocolate chips are in each Big Chip cookie at her bakery. She randomly selects a sample of 76

lozanna [386]

Using the t-distribution, the 90% confidence interval for the number of chocolate chips per cookie for Big Chip cookies is (8.374, 9.426).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 76 - 1 = 75 df, is t = 1.9921.

The other parameters are given as follows:

$\overline{x} = 8.9, s = 2.3, n = 76$ .

Hence the bounds of the interval are:

$\overline{x} - t\frac{s}{\sqrt{n}} = 8.9 - 1.9921\frac{2.3}{\sqrt{76}} = 8.374$

$\overline{x} + t\frac{s}{\sqrt{n}} = 8.9 + 1.9921\frac{2.3}{\sqrt{76}} = 9.426$
