Answer:

i = ($650)(0.08)(1) = $52

Step-by-step explanation:

The formula for simple interest is i = prt.  Here p = $650, r = 0.08 and t = 1 (year).  Then the simple interest Deanna paid for this one year loan was

i = ($650)(0.08)(1) = $52

Find the values of a and b.
aksik [14]

Answer:

  a = 144

  b = 67

Step-by-step explanation:

Where a transversal meets parallel lines, consecutive interior angles are supplementary.

<h3>Angles</h3>

  a° +36° = 180° . . . . . . consecutive angles are supplementary

  a = 144 . . . . . . . . . . divide by ° and subtract 36

  b° +113° = 180° . . . . . . consecutive angles are supplementary

  b = 67 . . . . . . . . . . divide by ° and subtract 113

Find the slope of the line through the pair of points a (2,-3) p(2,9)
Katarina [22]
(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)

To determine the slope using two points lie on the line, we could use the following formula
m = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

plug in the numbers
m = \dfrac{9-(-3)}{2-2}
m = \dfrac{9+3}{0}
m = \dfrac{12}{0}
m = undefined

The slope is undefined, the line is vertical

A large sample of tires from cabs driven within a city have an average tire tread depth of 0.25cm at the end of the winter. If t
frutty [35]

Answer:

0% probability cab tires depths would be shallower than 0.25cm.

Step-by-step explanation:

Problems of normally distributed samples can be 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 = 2.2, \sigma = 0.33

What is the probability cab tires depths would be shallower than 0.25cm.

This probability is the pvalue of Z when X = 0.25. So

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

Z = \frac{0.25 - 2.2}{0.33}

Z = -5.9

Z = -5.9 has a pvalue of 0.

0% probability cab tires depths would be shallower than 0.25cm.
