4 0

Answer:

<h3>★ <u>11/</u><u>3</u><u>0</u> is the right answer. ★</h3>

Step-by-step explanation:

Number of male students who got 'A' in the test is 11
Number of female students who got 'A' in the test is 19
Total students who got 'A' in the test is 30
Probability that the male student got an 'A' is P(A | male) = (Number of male students who got 'A' in the test)/(Number of total students who got 'A' in the test) = <em><u>11/</u></em><em><u>3</u></em><em><u>0</u></em>

Each tile is 3/2 feet by 3/2 feet. There are 10 tiles on the bathroom floor.

Yuki888 [10]

9514 1404 393

Answer:

22.5 square feet

Step-by-step explanation:

The area covered by one tile is the product of its dimensions:

A = lw

A = (3/2 ft)(3/2 ft) = 9/4 ft²

The area covered by 10 tiles is 10 times the area covered by one tile. The area covered is ...

covered by tiles = 10 × 9/4 ft² = 90/4 ft²

covered by tiles = 22.5 ft²

22 1/2 square feet is the area covered by tiles.

The functions q and r are defined as follows

kolezko [41]

Answer:

98

Step-by-step explanation:

So we have the two functions:

$g(x)=-2x-2\text{ and } r(x)=x^2-2$

And we want to find the value of r(g(4)).

To do so, first find the value of g(4):

$g(x)=-2x-2\\g(4)=-2(4)-2\\$

Multiply:

$g(4)=(-8)-2$

Subtract:

$g(4)=-10$

Now, substitute this into r(g(4)):

$r(g(4))\\=r(-10)$

And substitute this value into r(x):

$r(-10)=(-10)^2-2$

Square:

$r(-10)=100-2$

Subtract:

$r(-10)=98$

Therefore:

$r(-10)=r(g(4))=98$

Triangle and triangle are similar. What is the measure of side ?

snow_lady [41]

When two triangles are similar, they're sides are in proportion.

In order to find the unknown side, we first have to find the ratio of the larger triangle to the smaller triangle.

We can use the sides TV and LN to make the proportion.

$\frac{LN}{TV}$ = $\frac{21}{6}$

The ratio between the two triangles is 21:6

Now we can solve for the unknown side.

$\frac{21}{6}$ = $\frac{LM}{8}$

Cross multiply:

8 * 21 = 6 * LM

168 = 6LM

Divide both sides by 6:

LM = 28

The unknown side's length is 28 centimeters

Good luck!
