n your notebook, set up the following subtraction in a vertical format and select the correct answer. Reduce 7y + 2y 2 - 7 by 3
exis [7]

Answer:

\frac{2y^2+7y-7}{3-4y}

Step-by-step explanation:

We are given

\frac{7y+2y^2-7}{3-4y}

we can rewrite it as

\frac{2y^2+7y-7}{3-4y}

we know that

2y^2+7y-7 can not be factored

so, we can not reduce this expression

because this is the only way to reduce it

so, we get reduced form as

\frac{2y^2+7y-7}{3-4y}

A police officer claims that the proportion of accidents that occur in the daytime (versus nighttime) at a certain intersection
Roman55 [17]

Answer: -1.78

Step-by-step explanation:

As per given description, we have

Population proportion : p=0.35

Sample size : n= 500

Sample proportion : \hat{p}=\dfrac{156}{500}=0.312

Test statistic for population proportion :-

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\\\=\dfrac{0.312-0.35}{\sqrt{\dfrac{0.35(1-0.35)}{500}}}\\\\=-1.78146747757\ \ \text{(Simplified)}\\\\\approx-1.78

Hence, the test statistic for this hypothesis test for a proportion= -1.78

The divisor of 0.004 is almost zero. What does this tell you about the quotient?
nasty-shy [4]

Answer:

  Its magnitude will be larger than 0.004.

Step-by-step explanation:

When a divisor is less than 1, the quotient will be greater than the dividend.

When the divisor is "almost zero", the quotient will be much greater than the dividend. Here, the dividend may be considered to be "almost zero", so we cannot say anything about the actual quotient except to say its magnitude will be greater than the dividend.

_____

The dividend is positive, so the quotient will have the same sign as the divisor. (Negative divisors can be "almost zero," too.)
