The weight, in pounds, of a newborn baby t months after birth can be modeled by the equation W=10+2t What is the slope of the eq

Zanzabum

Answer:

m = 2

Step-by-step explanation:

W=10+2t has the form y = mx + b, the slope-intercept form. Comparing

y = b + mx to

w = 10 + 2t

we see that the slope, m, is 2. This signifies that the baby gains 2 pounds per month shortly after birth.

Determine the critical value or values for a one-mean z-test at the 10% significance level if the hypothesis test is left-tailed

Ugo [173]

Answer: 1.282

Step-by-step explanation:

Given : Significance level : $\alpha= 10\%=0.10$

The alternative hypothesis : $H_a:\mu$ , which is left tail-ed , it means the test is left -tailed test i.e. one -tailed test.

By using the standard normal distribution table , we have

The critical value for a one-mean z-test corresponding to the significance level 0.10 is 1.2815515 or approximately 1.282

Hence, the critical value or values for a one-mean z-test at the 10% significance level if the hypothesis test is left-tailed = 1.282

This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive an

maxonik [38]

Answer:

5.0 ft-lbf

Step-by-step explanation:

The force is

$F = \dfrac{9}{6^x}$

This force is not a constant force. For a non-constant force, the work done, <em>W</em>, is

$W = \int\limits^{x_2}_{x_1} {F(x)} \, dx$

with $x_1$ and $x_2$ the initial and final displacements respectively.

From the question, $x_1 =0$ and $x_2 = 12$ .

Then

$W = \int\limits^{12}_0 {\dfrac{9}{6^x}} \, dx$

Evaluating the indefinite integral,

$\int\limits \dfrac{9}{6^x} \, dx =9 \int\limits\!\left(\frac{1}{6}\right)^x \, dx$

From the rules of integration,

$\int\limits a^x\, dx = \dfrac{a^x}{\ln a}$

$9 \int\limits \left(\frac{1}{6}\right)^x \, dx = 9\times\dfrac{(1/6)^x}{\ln(1/6)} = -5.0229\left(\dfrac{1}{6}\right)^x$

Returning the limits,

$\left.-5.0229\left(\dfrac{1}{6}\right)^x\right|^{12}_0 = -5.0229(0.1667^{12} - 0.1667^0) = 5.0229 \approx 5.0 \text{ ft-lbf}$

Which square root should be placed between the number 17 and 18 on the number line.

Murrr4er [49]

17^2 = 289
18^2 = 324
Any of the numbers between 289 and 324 exclusive will have a root between 17 and 18
Eg sr(300) = 17.3205... is between 17 and 18 on the number line.
