Answer:

The answer in one common tangent only ⇒ answer (B)

Step-by-step explanation:

∵ The two circles touch internally in a common point

* At this point we can draw only one tangent

∵ This point is common in the two circles

∴ The tangent will be common for the two circles

∴ There is only one common tangent can be draw passing

through the common point which the two circles

touch each other on it

∴ The answer is (B)

: A store has 15 cars of a certain brand. Among them, 7 are black, 6 are gray and 2 are white. Another store wishes to buy 3 car

EleoNora [17]

Answer:

Probability of function ' x ' is $\frac{1}{13}$

Step-by-step explanation:

Store - 1

Total number of car = 15.

The number of

Black car = 7.

Grey car = 6.

White car = 2.

Store -2

The number of car wishes to buy = 3 car.

The number of black car sold = x .

The probability of 'x' = ?.

P ( x ) = P ( first black ) * P ( second black ) * P ( third is black )

P ( x ) = $\frac{7}{15} *\frac{6}{14} *\frac{5}{13}$ = $\frac{1}{13}$

So the probability of number of car sold is black or P ( x ) = $\frac{1}{13}$

In a survey of 302 registered voters, 167 of them wished to see Mayor Waffleskate lose her next election. Find a point estimate

Ivahew [28]

Answer:

A point estimate for the proportion of registered voters who wish to see Mayor Waffleskate defeated is of 0.553.

Step-by-step explanation:

Point estimate:

The point estimate of a proportion is the sample proportion(number of desired outcomes divided by the number of total outcomes).

Find a point estimate for the proportion of registered voters who wish to see Mayor Waffleskate defeated.

167 out of 302. So

$p = \frac{167}{302} = 0.553$

A point estimate for the proportion of registered voters who wish to see Mayor Waffleskate defeated is of 0.553.
