Answer:

Your answer will be 0.80

Step-by-step explanation:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.60 + 0.30 - 0.10

P(A or B) = 0.80

Santa gave kittens to 13 boys and girls. What is the ratio of kitten ears to kitten tails?

SVEN [57.7K]

Answer:

$Ratio = 2 : 1$

Step-by-step explanation:

Given

$Population = 13$ --- Boys & Girls

Required

Determine the ratio of the kitten ears to the tails

A kitten has 1 tail and 2 ears.

Assume each individual got 1 kitten each

This implies that,

$Number\ of\ tails= 1 * 13$

$Number\ of\ tails= 13$

$Number\ of\ ears= 2* 13$

$Number\ of\ ears= 26$

The ratio of ears to tail is then calculated as follows:

Ratio = Number of ears : Number of tails

This gives

$Ratio = 26 : 13$

Divide by 13

$Ratio = 26/13 : 13/13$

$Ratio = 2 : 1$

What is the result of isolating y2 in the equation below?

lyudmila [28]

STEP-BY-STEP SOLUTION:

( x + 4 )^2 + y^2 = 22

x^2 + 2 × x × 4 + 4^2 + y^2 = 22

x^2 + 8x + 16 + y^2 = 22

y^2 = 22 - x^2 - 8x - 16

y^2 = - x^2 - 8x + 6

FINAL ANSWER:

Therefore, the answer is:

D. y^2 = - x^2 - 8x + 6

Answer:

About 9.1 yards tall.

Step-by-step explanation:

So, we can draw the right triangle shown below:

We want to find h.

Since we know the angle and the side adjacent to the angle and we wan to find the opposite side, we will use the tangent ratio:

$\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}$
