Theresa has an umbrella stand at the beach. - All of them are blue, except for six. - All of them are yellow, except for six. -

Dmitry [639]

Answer:

3 Blue Umbrellas

Step-by-step explanation:

Given

$B \to Blue$

$Y \to Yellow$

$R \to Red$

From the question, we have:

$Y + R = 6$ ---- i.e. 6 are not blue

$B + R = 6$ ---- i.e. 6 are not yellow

$B + Y = 6$ ---- i.e. 6 are not red

Required

The number of blue umbrellas

Make B the subject in: $B + Y = 6$

$B = 6 - Y$

Substitute: $B = 6 - Y$ in $B + R = 6$

$6 - Y + R = 6$

Collect like terms

$R - Y = 6 - 6$

$R - Y = 0$

Rewrite:

$R = Y$

Substitute $R = Y$ in $Y + R = 6$

$Y + Y = 6$

$2Y = 6$

Divide both sides by 2

$Y=3$

Recall that: $B = 6 - Y$

$B = 6 - 3$

$B = 3$

Solve the equation 5(x-2)=7(x+4) for x

Sphinxa [80]

Answer:

$\boxed{\bold{x=-19}}$

Step By Step Explanation:

Expand $\bold{5\left(x-2\right): \ 5x-10}$

Expand $\bold{7\left(x+4\right): \ 7x+28}$

$\bold{5x-10=7x+28}$

Add 10 To Both Sides

$\bold{5x=7x+38}$

Subtract 7x From Both Sides

$\bold{5x-7x=7x+38-7x}$

Simplify

$\bold{-2x=38}$

Divide Both Sides By -2

$\bold{\frac{-2x}{-2}=\frac{38}{-2}}$

Simplify

$\bold{x=-19}$

A new car that is a gas- and electric-powered hybrid has recently hit the market. The distance travelled on 1 gallon of fuel is

Darya [45]

Answer:

15.87% probability that the car travels more than 53 miles per gallon.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 45, \sigma = 8$
