What is v?<br> -15V-40 = 23-8V
Andrew [12]

Answer:

V = -9

Step-by-step explanation:

-15V - 40 = 23 - 8V

The objective is to get V alone. To do this, first subtract -15V from both sides. Since -15V is a negative, subtracting it will be adding a positive.

-40 = 23 + 7V

Now that there is only one term with the variable V, subtract 23 from both sides.

-63 = 7V

Finally, divide both sides by 7 to get V completely isolated.

-9 = V.

The final answer is V = -9.

frozen [14]

The quadrilateral VWXY is a trapezoid.

<h3>What is a quadrilateral?</h3>

A quadrilateral is a polygon with four sides and four angles. Types of quadrilaterals are parallelogram, rectangle, rhombus, square and trapezoid.

A Trapezoid is a quadrilateral with a pair of opposite parallel sides.

Given a quadrilateral VWXY, WX = 67, XY = 45, YV = 33, VW = 55, and all the angles are different, hence:

The quadrilateral VWXY is a trapezoid.

Scores on a test have a mean of 78.2 and 8 percent of the scores are above 89. The scores have a distribution that is approximat
anyanavicka [17]

Answer:

The standard deviation is 7.7

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 = 78.2

8 percent of the scores are above 89

This means that X = 89 has a pvalue of 1 - 0.08 = 0.92. So when Z = 89, Z = 1.405.

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

1.405 = \frac{89 - 78.2}{\sigma}

1.405\sigma = 10.8

\sigma = \frac{10.8}{1.405}

\sigma = 7.7

The standard deviation is 7.7
