Helen = 30 T (T = tickets)
Gina = 30 + 20 = 50 T
20% of 50 = 10
30 + 10 = 404
50 - 10 = 40
Gina must give 20% of her tickets for them to have equal amount of tickets.
Hope this helps!!
The question is not clear because the Debbie solution lines are not visible. Nevertheless,
The correct solution for this linear equation is the following:
<span>3(x + 4) − 2 = 16
</span><span>3(x + 4) = 16 + 2
</span><span>3(x + 4) = 18
</span>(x + 4) = 18/3
(x + 4) = 6
x = 6 - 4
x = 2
1/4 of 1/2 of a pizza is an 1/8 of a pizza.
(1/4)*(1/2)=1/8
Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. From the histogram, the relative frequency of houses with a value less than 500,000 is 0.34 and 0.37
-#The probability can therefore be calculated as:

Hence, the probability of the house value being less than 500,000 is o.71
b.
-From the info provided, we calculate the mean=403 and the standard deviation is 278 The probability that the mean value of a sample of n=40 is less than 500000 can be calculated as below:

Hence, the probability that the mean value of 40 randomly selected houses is less than 500,000 is 0.9863
