A fraction equivalent to 4/5 is 8/10, also 12/15. To find an equivalent fraction all you have to do is multiply the numerator and denominator by the same number.

I hoped i help :)

A triangle has an area of 80 yd^2 and a height of 10 yd. How long is the base of a triangle? Enter in the answer in the box.

sdas [7]

Answer:

Length of the base is 16 yards.

Step-by-step explanation:

We are given that,

Area of the triangle = 80 yd²

Height of the triangle = 10 yards

Since, we know,

Area of a triangle = $\frac{1}{2}\times Base \times Height$

So, we get,

$80=\frac{1}{2}\times Base \times 10$

i.e. $80=Base \times 5$

i.e. $Base=\frac{80}{5}$

i.e. Base = 16 yards

Thus, the length of the base is 16 yards.

The pregnancy length in days for a population of new mothers can be approximated by a normal distribution with a mean of 270 day

dusya [7]

Answer:

a) 281 days.

b) 255 days

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:

$\mu = 270, \sigma = 8$
