ASHA 777 [7]

<span>This would be a bell curve with a z-score of greater than +2.00, since 3 minutes is exactly two standard deviations greater than the mean of 2.00. Looking at a z-score table for the proportion of the curve that lies in the 1-tailed area greater than 2.00, we find that the value is .0228. This would be the probability that the conversation is over three minutes: 0.0228 or 2.28%.</span>

the volume of a rectangular pyramid is 1.32 cubic inches. the height of the pyramid is 1.1 inches and the length of the base is

worty [1.4K]

Work:

V = l × w × h

1.32 = 1.2 × w × 1.1

1.32 = 1.32 × w

1.32 ÷ 1.32 = 1

Answer:

1 inch = width

For which graph is the parent function y=x^2

mylen [45]

y = x² is the parent function of a parabola opens up and has a vertex at (negative 1, negative 2)

<h3>What is the standard equation of a parabola ?</h3>

The standard equation of a parabola is given by

y =a(x-h)² +k

Vertex at h , k

It is given that It has to be chosen from the options that whose parent function is

y = x²

As the plot of the first option is done , which is shown in the figure ,

The parabola is given by

y = (x +1)² +2

and the parent function is y = x²

Therefore the Option 1 is the answer.

Which side length will form an obtuse triangle with side lengths 8 and 10

Ne4ueva [31]

Answer:

Option J 13

Step-by-step explanation:

we know that

If applying the Pythagoras Theorem

$c^{2}> a^{2} +b^{2}$ ----> is an obtuse triangle

$c^{2}< a^{2} +b^{2}$ ----> is an acute triangle

$c^{2}= a^{2} +b^{2}$ ----> is a right triangle

where

c is the greater side

<em><u>Verify each case</u></em>

case F) we have

$c=10, a=6, b=8$

substitute

$10^{2}> 6^{2} +8^{2}$

$100> 100$ -----> is not true

Is a right triangle

case G) we have

$c=10, a=9, b=8$

substitute

$10^{2}> 9^{2} +8^{2}$

$100> 145$ -----> is not true

Is an acute triangle

case H) we have

$c=12, a=8, b=10$

substitute

$12^{2}> 8^{2} +10^{2}$

$144> 164$ -----> is not true

Is an acute triangle

case J) we have

$c=13, a=8, b=10$

substitute

$13^{2}> 8^{2} +10^{2}$

$169> 164$ -----> is true

Is an obtuse triangle
