A) 20 households are randomly selected from the town; 8 own a dog
why: when conducting a survey to determine approximations in a population, it’s best to eliminate any and all biases for best results. Households who live near a park or have their own front yards will skew results as the rest of the population may not have access to those things, thus are more likely to not have a dog.
b) 8/20= 0.40
600*0.40= 240
The probability that a point is chosen at random in the shaded region will be 0.25.
<h3>What is probability?</h3>
Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
Probability = (Favorable event) / (Total event)
The area of the shaded circle below is 78.5 square inches.
The area of the large circle is 314 square inches.
A shaded circle is inside of a larger unshaded circle.
Then the probability that a point is chosen at random in the shaded region will be
P = 78.5 / 314
P = 1 / 4
P = 0.25
Then the correct option is A.

Hello :
let : z = 4-3ii z' = -2+7i
the distance between the points 4-3i and -2+7i is : <span>|z - z' |
</span> |z - z' | = |4-3i+2-7i| = |6-10i | =√(6²+(-10)²) =√136
Answer:
60%
Step-by-step explanation:
Just divide 15 by 25 and then move the decimal point 2 places to the right. Then turn that number into a percentage.
Your answer is 110. You take 10 and divide it by 750. = 75 then you take 75. Divided 8250. = 110
