18 out of 24 is 18/24 which is 18/24*100=75 percent.

Answer:75%

Step-by-step explanation:

x% of 24=18

x/100 x 24=18

24x/100=18

Cross multiply

24x=18x100

24x=1800

Divide both sides by 24

24x/24=1800/24

x=75

75 percent pass the test

Artemon [7]

Answer:

? = 57

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos ? = adj/ hyp

cos ? = 14/26

Taking the inverse cos of each side

cos ^-1 ( cos ?) = cos ^-1 ( 14/26)

? = 57.42102961

Total Number of surveyed households =125

We want to determine the probability that a randomly selected household would have a laptop given that it does not have a tablet.

Written in Probability notation: P(Laptop|No Tablet)

$P(Laptop|No Tablet)=\dfrac{P(L\cap T')}{P(T')} \\=\dfrac{31/125}{95/125}\\=\dfrac{31}{95}\\\\=0.326$

The correct option is C,
