First you take 9 and divide it by 3. since 9 is 3/7 of n, 9÷3 would be 1/7. so 9÷3 is 3, so you take that and multiply it by 7 to get 7/7 or the whole number. which in this case is 21. (:

Is x=-2 a positive slope
victus00 [196]

Answer:

No

Step-by-step explanation:

x = -2 represents a vertical line that intersects the x axis at the point (-2, 0). Since the line is vertical, the slope is undefined making it not have a positive slope.

Caroline has a unique pet chimpanzee that is relatively likely to have twins. Each pregnancy is independent, and
mrs_skeptik [129]

Answer: 2=.36, 3=.48, 4=.16

Step-by-step explanation:

If we let "S" represent 1 baby and "D" represent 2 babies, the sample space for the chimpanzee's 2 pregnancies is {SS, SD, DS, DD}.

We can find the probability of each possible outcome by multiplying the probability of the independent events leading to that outcome.

Outcomes:. Probability:

SS. .60 x .60 = .36

SD. .60 x .40 = .24

DS. .40 x .60 = .24

DD. .40x .40 =.16

Total. 1.00

Lastly group the similar outcomes. SD+DS= .48

A motorboat left a harbor and traveled to an island at an average rate of 13 knots. The average speed on the return trip was 10
vlada-n [284]

Answer:

The distance between harbor & the island D = 72.12 km

Step-by-step explanation:

Let the total distance between harbor & island = D

Motor boat going to the island at speed S_{1} = 13 knots = 24 \frac{km}{hr}

Return speed of the motorboat S_{2} = 10 knots = 18.52 \frac{km}{hr}

The total time taken for both journey = 6.9 hours

\frac{D}{S_{1} } + \frac{D}{S_{2} } = 6.9

\frac{D}{24} + \frac{D}{18.52} = 6.9

D (\frac{1}{24} + \frac{1}{18.52} ) = 6.9

D ( 0.0956 ) = 6.9

⇒ D = 72.12 km

This is  the distance between harbor & the island.
