Evaluate 1+(-2/3)-(-m)where m = 9/2

slava [35]

Answer:

29/6

Step-by-step explanation:

The expression that we have to evaluate in this problem is

$1+(-\frac{2}{3}) -(-m)$

for $m=\frac{9}{2}$ .

First of all, we re-arrange the expression. We know that:

- The product of a positive number (+) and a negative number (-) is negative (-)

- The product of a negative number (-) and a negative number (-) is positive (+)

So we can rewrite the expression as

$1-\frac{2}{3}+m$

Also, we can combine the two numerical terms:

$1-\frac{2}{3}=\frac{3}{3}-\frac{2}{3}=\frac{1}{3}$

Therefore the expression becomes

$\frac{1}{3}+m$

Now we can substitute $m=\frac{9}{2}$ , and we find:

$\frac{1}{3}+\frac{9}{2}=\\\frac{2}{6}+\frac{27}{6}=\\\frac{2+27}{6}=\frac{29}{6}$

PLEASE HELP!!! HURRY EMERGENCY !! 50 PTS AND BRAINLIEST

makkiz [27]

Answer:

graph of h(x)= a slope of 2, and the y-intercept is 0.

graph of g(x)= a slope of 1, and a y-intercept of 6.

graph of f(x)= a slope of 1, and a y-intercept of -6.

Step-by-step explanation:

The equation would be h(x)=(x-6)+(x+6) which is also equal to h(x)= 2x if you combine like terms. f(x) and g(x) equations are pretty straight forward.

Starting salaries of 90 college graduates who have taken a statistics course have a mean of $43,993 and a standard deviation of

inysia [295]

Answer:

a) E = 2482.90

b) 99% Confidence interval: (41510.1,46475.9)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ =$43,993

Sample size, n = 90

Alpha, α = 0.051

Sample standard deviation, s = $9,144

a) The margin of error

Formula:

$z_{critical}\text{ at}~\alpha_{0.01} = 2.576$

$E =z_{critical}\times \displaystyle\frac{s}{\sqrt{n}}\\\\E = 2.576\times \frac{9144}{\sqrt{90}}\\\\E = 2482.90$

b) 99% Confidence interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$43993 \pm 2482.90 = (41510.1,46475.9)$
