Answer:

$40\frac{5}{8}mm^2$

Step-by-step explanation:

To find the area of a triangle, one must use the formula,

$\frac{base*height}{2}$

It is given that

- base = $9\frac{3}{4}$

-height = $8\frac{1}{3}$

Substitute in the values and solve;

$\frac{9\frac{3}{4}*8\frac{1}{3}}{2}$

In order to multiply the two fractions, one must convert them from mixed number form to improper fraction form. This can be done by multiplying the denominator (the number under the fraction bar), by the "number" part of the mixed number, and then adding the result to the numerator (the number over the fraction bar;

- base = $9\frac{3}{4}=\frac{(9*4)+3}{4}=\frac{36+3}{4}=\frac{39}{4}$

- height = $8\frac{1}{3}=\frac{(8*3)+1}{3}=\frac{24+1}{3}=\frac{25}{3}$

Substitute,

$\frac{\frac{39}{4}*\frac{25}{3}}{2}$

Cross simplify,

$\frac{\frac{325}{4}}{2}$

Further simplify,

$\frac{325}{4}*\frac{1}{2}\\\\= \frac{325}{8}$

Convert back to a mixed number divide the numerator by the denominator, write the whole-number result as the number outside of the fraction, and the remainder as the numerator of the fraction,

$40\frac{5}{8}$

The distance that a Tesla model 3 can travel is normally distributed with a mean of 260 miles and a standard deviation of 25 mil

Alja [10]

Answer:

2.28% probability that a randomly selected Tesla model 3 can travel more than 310 miles

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:

$\mu = 260, \sigma = 25$
