Step-by-step explanation:
last week there were
62 + 60 + 2 = 124 customers.
that means that the fraction of the customers, who paid by credit card, was
2/124 = 1/62
in situations like that, when we use history data and try to predict future behavior, we use that past experience and extrapolate to a predicted result.
we simply say that we expect the same fraction, 1/62, if customers to use credit cards.
for the absolute number of predicted credit card customers we multiply the predicted number of customers by the expected fraction
1000 × 1/62 = 500/31 = 16.12903226... ≈ 16
so, he expects 16 credit card customers.
Answer:
22
Step-by-step explanation:
If it takes 3 hours at 30 km per hour than that 90 km total distance and at 45 km per hour that would mean that distance would be travelled in 2 hours. So the answer should be 2 hours
7.2 because you just add the -4.8 to cancel out the -4.8 on the right side. and you get 7.2
Answer:
Approx. 48 cm
Step-by-step explanation:
The two horizontal sides of this parallelogram have length 12 cm each.
The length of one slanting side can be estimated by (eye: the base of the triangle partially outlined with a dashed line is approx. 3 cm. Then, using the Pyth. Thm., we estimate the hypotenuse of this triangle to be
sqrt(3^2 + 10^2), or sqrt(109), which is approx. 10.45.
Thus, the estimated perimeter is
P = 2L + 2W, which, here, is
P = 2(12 cm) + 2(10.45 cm), or 44.9 cm.
The fourth answer, 48 cm, is the one closest to this estimated 44.9 cm.
