The mean age of Lincoln's tee-ball team is 5. Suppose one of his 7-year-old teammates quits the team, but a 6-year-old joins the

aleksandrvk [35]

Answer:

Depending on the amount of children in the tee ball team, the mean may be lowered drastically or minorly. However, the mean would no longer be 5, although it may round up to five, if it is a decimal.

Step-by-step explanation:

Hope that helps, I didn’t do a very good job of explaining that question. But the answer is no.

Answer:

Answer B: min. value at -6

Step-by-step explanation:

Complete the square of f(x) = x^2 - 2x - 5.

Note: Please use " ^ " to denote exponentiation, as shown.

Start with f(x) = x^2 - 2x - 5.

Identify the coefficient of the x term: it is 2.

Take half of that and square your result: (1/2)(2) = 1, and then 1^2 = 1.

Add and subtract this 1 between the 2x term and the constant term:

f(x) = x^2 - 2x + 1 - 1 - 5

Rewrite x^2 - 2x + 1 as a perfect square:

f(x) = (x - 1)^2 - 1 - 5, or f(x) = (x - 1)^2 - 6

Compare this to the standard form

f(x) = (x - h)^2 + k

We see that h = 1 and k = -6.

The vertex is located at (h, k); here, it's located at (1, -6).

Thus, the minimum value of this function is at the vertex (1, -6).

This agrees with Answer B: min. value at -6.

Suppose a normal distribution has a mean of 98 and a standard deviation of 6. What is P(x<110)? (The greater than sign is act

kvasek [131]

Using the normal distribution, the probability that x is less than 110 is:

A. 0.975.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given as follows:

$\mu = 98, \sigma = 6$

The probability is the <u>p-value of Z when X = 110</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{110 - 98}{6}$

Z = 2

Z = 2 has a p-value of 0.975.

Hence option A is correct.

First, let's see what the answer is when we follow this equation using PEMDAS.

5 + 4 x 2 + 6 - 2 x 2 - 1

5 + 8 + 6 - 4 - 1

Now, let's trying grouping 5 + 4 together, and solving it again.

(5 + 4) x 2 + 6 - 2 x 2 - 1

9 x 2 + 6 - 2 x 2 - 1

18 + 6 - 4 - 1

24 - 5

So, the parentheses go around 5 + 4 to get your answer!
