Answer:
You can use proportions by settling the ratio from the sample equal to the ratio from the population.
Explanation:
For Example is 3 out of 50 phones in a sample are defective, then an estimated 60 out of 1000 phones in a population are defective. this can be found by solving the proportion 3/50=x/1000 where x is the estimated number of defective phones in the population.
Answer:
Pythagoras theorem.
hypotenuse²=height²+base²
x²=15²+12²
x²=225+144
x²=329
x=329½
x=19.20
8.2 i think. I am so sorry if i’m wrong
Answer:
5 1/3
Step-by-step explanation:
We make
4/1 divided by 4/3 = 5 1/3
ABC is equal to MNP. This is because you have to look at the order of the angles/sides. ABC goes from A with 3 congruency arcs to B with 1 congruency arc. For MNP, start with M that has 3 congruency arcs then go to the next angle with one congruency arc which is N
