Answer:
Step-by-step explanation:
Researcher observes that 12 out 15 cats that approached him are males.
Therefore, number of Female Cats that approached him = 15 – 12 = 3
Answer:
a=8
Step-by-step explanation:
solve for a by adding 5 on both sides
4a=32
Now divid 4 on both sides
a=8
Answer:
14
Step-by-step explanation:
Total number of chips = 500
Percentage of green chips = 28%
P(green chips) = 0.28
Expected number of green chips from a simple of 50
Sample size, n = 50
p of green chips = 0.28
Recall:
Mean, m = n*p
Expected number of green chips = 50 * 0.28 = 14
14 green chips
Answer:
A
Step-by-step explanation:
When the temperature has a negativ sign on it, it is below zero
When the temperature is a natural number, it is above zero
Answer:
<h3>Daniel is correct</h3>
Step-by-step explanation:
Given the polynomial P(x) = x^2-3x-10
To check that the remainder is zero if divided by x - 5, we will first have to equate x - 5 to zero and get x;
x - 5 = 0
x = 5
Then find P(5)
P(5) = 5^2 - 3(5) - 10
P(5) = 25 - 15 - 10
P(5) = 25-25
P(5) = 0
<em>This shows that x - 5 is a factor of the polynomial since P(5) gave us zero according to the factor theorem</em>
