What type of triangle is a 9.9 cm, 9 cm, 0.99 cm

1 answer:

6 0

It would be an isosceles triangle. Since there are two sides of the triangle that are congruent, it would be isosceles.

Isosceles has two congruent sides, scalene has none, and equilateral has three.

(A good tip to do is this: count the number of syllables in each word. Then take away two. That's how many sides that triangle has.)

Ex: i-so-sce-les has four syllables. Take away two, you get two. Therefore, an isosceles triangle has two congruent sides.

Hope that helps!

The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 1

melomori [17]

By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19

<h3>What is standard deviation?</h3>

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value

Here given that

The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15. 9 minutes. Based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes

mean=μ=60

standard deviation=σ=15.9

number of sample=n=40

$\bar{x}=63 \\$
