So we’re given $5 for the entry free, $2.50 per pound of blueberries, and $2 per pound of apples.
we clearly are looking for the equation that represent how Eva pays.
so the equation is 5(2.50b + 2a) because to calculate her total we need to multiply the $5 entry fee with the pounds per blueberries and apples. therefore giving us 5(2.50b + 2a).
V y are the 2 next leters
Scale factor is defined as
s=size of image / size of preimage.
Here BO is preimage.
B'O'=BO' is image, since the position of B is invariant, so B=B'.
So scale factor = B'O'/BO = 9/27 = 1/3.
d. Kate = 325 and Lisa = 575
because it says that LIsa has scored 250 points more.
Answer:
The chance that there will be exactly 2 heads among the first five tosses and exactly 4 heads among the last 5 tosses is P=0.0488.
Step-by-step explanation:
To solve this problem we divide the tossing in two: the first 5 tosses and the last 5 tosses.
Both heads and tails have an individual probability p=0.5.
Then, both group of five tosses have the same binomial distribution: n=5, p=0.5.
The probability that k heads are in the sample is:

Then, the probability that exactly 2 heads are among the first five tosses can be calculated as:

For the last five tosses, the probability that are exactly 4 heads is:

Then, the probability that there will be exactly 2 heads among the first five tosses and exactly 4 heads among the last 5 tosses can be calculated multypling the probabilities of these two independent events:
