You paint 1/3 of a wall and 1/4 of an hour at that rate how long will it take you to paint one wall

1 answer:

8 0

If we want to get to 3/3 from 1/3 we times it by 3 so we must do that to the time as well so 1/4 times 3 =3/4hour or 45 minutes

Is x^2-1 a polynomial

77julia77 [94]

Answer:

Yes it's a binomial.

Step-by-step explanation:

A polynomial is an expression with more than one term that often has variables and exponents on the variable. Since this has two terms separated by a subtraction sign with one term being a variable to the exponent of 2 then this is a polynomial. It is called a binomial. More than 2 terms are referred exclusively as a polynomial with ___ terms.

Assume a standard deviation of LaTeX: \sigma = 0.75σ = 0.75. You plan to take a random sample of 110 households, what is the pro

olchik [2.2K]

Answer:

P(2.50 < Xbar < 2.66) = 0.046

Step-by-step explanation:

We are given that Population Mean, $\mu$ = 2.58 and Standard deviation, $\sigma$ = 0.75

Also, a random sample (n) of 110 households is taken.

Let Xbar = sample mean household size

The z score probability distribution for sample mean is give by;

Z = $\frac{Xbar-\mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

So, probability that the sample mean household size is between 2.50 and 2.66 people = P(2.50 < Xbar < 2.66)

P(2.50 < Xbar < 2.66) = P(Xbar < 2.66) - P(Xbar $\leq$ 2.50)

P(Xbar < 2.66) = P( $\frac{Xbar-\mu}{\frac{\sigma}{\sqrt{n} } }$ < $\frac{2.66-2.78}{\frac{0.75}{\sqrt{110} } }$ ) = P(Z < -1.68) = 1 - P(Z $\leq$ 1.68)

= 1 - 0.95352 = 0.04648

P(Xbar $\leq$ 2.50) = P( $\frac{Xbar-\mu}{\frac{\sigma}{\sqrt{n} } }$ $\leq$ $\frac{2.50-2.78}{\frac{0.75}{\sqrt{110} } }$ ) = P(Z $\leq$ -3.92) = 1 - P(Z < 3.92)

= 1 - 0.99996 = 0.00004

Therefore, P(2.50 < Xbar < 2.66) = 0.04648 - 0.00004 = 0.046

Please Help!! First correct answer + branliest Evaluate without calculator: 167^2−167·67

NARA [144]

Answer: 16700

Step-by-step explanation:

First, we must factor 167^2-167*67

Factoring out 167 gives:

167(167-1*67)

Following Order of Operations, you get 167(167-67) which then gets 167(100)

Then, multiply and get 16700
