Answer:

40%

Step-by-step explanation:

Probability that student is a male Given that it's a senior ::

Recall :

P(A | B) = (AnB) / B

Hence, we have ;

P(male | Senior) = number of (Male n Senior) / total Senoirs

From the table :

Total seniors = 2 + 3 = 5

Male n Seniors = 2

P(male | Senior) = 2 / 5 = 0.4 = 40%

If j = k, then j + 9 = k + 9 represents which algebraic property

sleet_krkn [62]

Answer:

c) The given expression represents Addition Property of Equality.

Step-by-step explanation:

Here, the given expression is j = k

Now by ADDITION PROPERTY OF EQUALITY:

The property that states that if you add the same number to both sides of an equation, the sides remain equal.

So, if A = B ⇒ A + x = B + x

Now, here given that j = k

If we add the same number 9 on both the sides, the equation remains undisturbed.

⇒ j + 9 = k + 9

Hence, the above expression represents Addition Property of Equality.

A pyramid has a base 16 inches x 16 inches and a slant height of 10 inches. what is the volume in cubic inches

gizmo_the_mogwai [7]

Answer:

512 in³

Step-by-step explanation:

The height perpendicular to the base is the leg of a right triangle with hypotenuse 10 in and other leg 8 in. Using the Pythagorean theorem, we can find it as ...

h² +8² = 10²

h² = 100 -64 . . . . . subtract 8²

h = 6 . . . . . . . . . . . . take the square root of 36

Then the volume is found using ...

V = (1/3)Bh = (1/3)(16 in)²(6 in) = 512 in³

The volume is 512 cubic inches.

_____

The 8-inch dimension used above comes from half the distance between the center of one side of the base to the center of the opposite side. (16 in)/2 = 8 in.

Answer:

Slope Intercept Form: y=3x+10

Slope: 3

y: 10

Step-by-step explanation:

y-3x=10 Add 3x to both sides. The y has to be isolated.

So it is y=10+3x So we have to reorder it so y=3x+10
