Given :

A pre-image arrow pointing east is rotated 135° clockwise.

To Find :

In which direction is the image arrow point.

Solution :

90° clockwise shift make it south.

Now, remaining angle for rotation ( 135 - 90 )° = 45°.

So, direction of moving 45° more clockwise makes it 45° west of south or 45° south of west.

Hence, this is the required solution.

Suppose the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ =

hammer [34]

Answer:

The swimmer must complete the 200-meter backstroke in no more than 130 seconds.

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:

$\mu = 141, \sigma = 7$

Fastest 6%

At most in the 6th percentile, that is, at most a value of X when Z has a pvalue of 0.07. So we have to find X when Z = -1.555.

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

$-1.555 = \frac{X - 141}{7}$

$X - 141 = -1.555*7$

$X = 130$

The swimmer must complete the 200-meter backstroke in no more than 130 seconds.

Mark is cutting construction paper into rectangles for a project. He needs to cut one rectangle that is 12 inches × 13 1/3 inche

Answer: 265.9167 square inches (rounded)

Step-by-step explanation:

Shoot, okay if this is wrong, shame on me:

All you do is find the areas of each rectangle and add them together.

(12 × 13 1/3) + (10 1/4 x 10 1/3) = 265.9167 (rounded) square inches. Or as a fraction: 3191/12

When faced with an unknown variable in a maths problem, it is advised to find the subject formula and then use it to solve the equation to find the answer.

<h3>What is an Unknown Variable?</h3>

This refers to the type of variable in a given equation that has to be solved for because its properties or value is not known.

Hence, we can see that when faced with an unknown variable in a given math problem, it is better to find the subject formula, then input the value of this into an equation, to find the value of the variable.
