PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Burka [1]

Answer:  d) 0.9693

<u>Step-by-step explanation:</u>

refer to the z-table attached.  

The table shows the percent from the MEAN.  The percent below the mean is 50% so that needs to be added to the value in the table.  

Look on the left side for 1.8 and the top for 0.07 (which is 1.87).  

The value is 0.4693 --> add 0.5 to that value to get 0.9693.

A triangle has 2 sides that are 9 inches and the bottom is 6 inches what is the height?
Elanso [62]

The height of the isosceles triangle is 8.49 inches.

<h3>How to find the height of the triangle?</h3>

Here we have a triangle such that two of the sides measure 9 inches, and the base measures 6 inches.

So this is an isosceles triangle.

We can divide the isosceles triangle into two smaller right triangles, such that the side that measures 9 inches is the hypotenuse, the base is 3 inches, and the height of the isosceles triangle is the other cathetus.

By Pythagorean's theorem, we can write:

(9in)^2 = (3 in)^2 + h^2

Where h is the height that we are trying to find.

Solving that for h we get:

h = √( (9 in)^2 - (3in)^2) = 8.49 inches.

We conclude that the height of the isosceles triangle is 8.49 inches.

The equation of a line with slope m= - 1/4 and including point (-3, 5) is y= - 1/4 x - 4.
raketka [301]

Answer:

False

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - \frac{1}{4}, hence

y = - \frac{1}{4} x + c ← is the partial equation

to find c substitute (- 3, 5) into the partial equation

5 = \frac{3}{4} + c ⇒ c = \frac{17}{4}

y = - \frac{1}{4} x + \frac{17}{4} ← equation of line
