Answer:

1/12

Step-by-step explanation:

In a bag, there are 3 red marbles, 5 white marbles, and 2 blue marbles. One marble is selected and then it is not replaced. Find the probability of selecting a white marble 3 times in a row.

The total number of marbles in the bag is given as:

3 red + 5 white + 2 blue

= 10 marbles

The probability of selecting a white marble 3 times in a row without replacement is calculated as:

5/10 × 4/9 × 3/8

= 60/720

= 1/12

Point Q’ is the image of Q (3,-4) under a reflection across the x-axis
7nadin3 [17]

Answer:

Q' (-3,4)

Step-by-step explanation:

A reflection across the x-axis would mean that only the x value of the point would change. This means that the y value would still be 4. To find the x value, just flip it to a negative. The negative of 3 is -3

Over the summer, for every 14 Okra seeds Dana planted, 9 plants grew. If he planted 182 seeds, how many grew into plants?
vova2212 [387]
Simple...

you have: For every 14 seeds that Okra seeds Dana planted 9 of them grew; if he planted 182 seeds..how many grew?

Set up an equation...

\frac{9}{14} = \frac{x}{182}

Cross multiply....

14*x=14x

9*182=1638

14x=1638

\frac{14x}{14} = \frac{1638}{14} =117


x=117

This means that, for 182 seeds planted, 117 of them grew to be plants.

Thus, your answer.

Can two dot plots have the same median and range but not have completely different shapes?
Leona [35]
Yes because the median and range are not a function of the totality of the sample set, the median is just value that is halfway of the set and the range is the difference of the highest and lowest value. As long as the lowest and highest value and the halfway value are the same in each set, the median and range will be equal no matter what the other values of the set are.
