sorry im bad at explaining things but i added a picture
Answer:
$54.25
Step-by-step explanation:
4/5 yards of lace = $5.60
Price per yard = 5.60 ÷ 4/5
= 5.60 × 5/4
= 28 /4
= $7 per yard
The class decided to buy another 7 3/4 yd
Cost of 7 3/4 yd = cost per yard × number of yards
= $7 × 7 3/4
= $7 × 31/4
= 217 / 4
= $54.26
Cost of 7 3/4 yd = $54.25
Kindly note that the question says 4; maybe the final question was intended to be the probability that he gets exactly 2 of the 4 correct. However. If it is the other way round. This a e procedure used in the solution should also be followed.
Answer:
0.21
Step-by-step explanation:
Number of options = 4
One correct answer per option ; hence, the probability of success, p = 1/4 = 0.25
Using the binomial probability relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
x = 2 ; n = 4
p = 0.25 ; 1 - p = 0.75
P(x = 2) = 4C2 * 0.25^2 * 0.75^2
P(x = 2) = 6 * 0.0625 * 0.5625
P(x = 2) = 0.2109375
P(x = 2) = 0.21 (2 decimal places)
Note : if the question was 3, then put, n = 3 instead of 4
Answer:
1/4 is equal to .25 as a decimal.
Step-by-step explanation:
I hope this is what you are asking for!
