30 points if correct. Select all the are true.
ivann1987 [24]

Answer:

Options B,C and E are correct choices.

Step-by-step explanation:

We are asked to find correct answers for the given box and whisker plots.

Let us our options one by one.

A. This option is false as lowest value for children's cereals is 30 and highest value for adults is 35.

B. This option is correct. We can see our upper value for combined range will be 60 and lower value will be 5 and range is upper value- lower value.

60-5=55

C. Since we know that we can find spread of data by its range.

\text{Range for children's cereals}=60-30=30

\text{Range for adult's cereals}=60-30=30

So option C is correct indeed.

D. This options is false because for adults mean and median are different while for children mean and median are same.

E. We can see that median for children's cereals is 45 and it is about 12 for adults.

We can see that 12*3. So median amount of sugar in children's cereals is 3 times as much as the median amount of sugar in adult's cereals.

Therefore, options B,C and E are correct choices.

It says The temperature doubled

It means the temperature has been doubled ,

if earlier it was t , then now its 2t

Now in the question it says the the temperature doubled

And now the temperature is 32 degrees ,

so we double it to get the new temperature

and the double of 32 degrees is 64 degrees

So

The value of the expression when t = 32 degrees is 64 degrees
