PLEASE HELP! WILL MARK BRAINLIEST AND 30 POINTS
ArbitrLikvidat [17]

Answer:

 

The correct answer was given: Brain

y = (x+5)(x+2)

step-by-step explanation:

we are given the following the quadratic function and we are to rewrite it in intercept or factored form:  

y = x^2 + 7x + 10  

we can factorize the given quadratic function such that when multiplied, the factors give a product of 10 and when added, they give a result of 7.

y=x^2+5x+2x+10

y=x(x+5)+2(x+5)

y=(x+5)(x+2)

therefore, the factored form of the given function is y = (x+5)(x+2)

Forty-seven percent of fish in a river are catfish. Imagine scooping out a simple random sample of 25 fish from the river and ob
Alexxx [7]

Question options:

The standard deviation is 0.0998. The 10% condition is not met because there are less than 250 fish in the river.

The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river.

The standard deviation is 0.9002. The 10% condition is met because it is very likely there are more than 250 fish in the river.

The standard deviation is 0.9002. The 10% condition is not met because there are less than 250 fish in the river.

We are unable to determine the standard deviation because we do not know the sample mean. The 10% condition is met because it is very likely there are more than 250 fish in the river

Answer:

The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river

Explanation:

Formula to calculate standard deviation = √p(1-p)/n

Given p= population proportion

n= sample size

From the question,

We are given p(population proportion of catfish in the river)= 0.47

n(sample size of fish collected from river) = 25

The standard deviation using the formula above = √0.47(1-0.47)/25

= 0.0998

The 10% condition demands that a sample size be not less than 10% of the population

To check if the 10% condition was met, we know that a river will likely have up to 250 fish in it and so,

10% of 250= 0.10×250=25 fish

Therefore the option B chosen is correct
