Answer:

h = 11. 5.

Step-by-step explanation:

(4h - (21 - 8h)/3 = (15 + 6(h - 1)/2

Cross multiplying, we get:

2(4h - (21 - 8h) = 3(15 + 6(h - 1)

8h - 2(21 - 8h) = 45 + 18(h - 1)

8h - 42 + 16h = 45 + 18h - 18

8h + 16h - 18h = 45 - 18 + 42

6h = 69

h = 11. 5

Answer:

11.5

Step-by-step explanation:

$\frac{4h-(21-8h)}{3} = \frac{15 + 6(h - 1)}{2} \\ \frac{4h - 21 + 8h}{3} = \frac{15 + 6h - 6}{2} \\ 3(15 + 6h - 6) = 2(4h - 21 + 8h) \\ 45 + 18h - 18 = 8h - 42 + 16h \\ 27 + 18h = 24h - 42 \\ 18h - 24h = - 42 - 27 \\ - 6h = - 69 \\ h = \frac{ - 69}{ - 6} \\ cancel \: the \: minus \: signs \\ h= 11.5$

Answer:

$n=(\frac{2.33(19)}{7})^2 =39.996 \approx 40$

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean

$\mu$ population mean

$\sigma=19$ represent the assumed population standard deviation

n represent the sample size (variable of interest)

Confidence =0.98 or 98%

Me=0.07 represent the margin of error for this case

Solution to the problem

The margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (1)

And on this case we have that ME =7 and we are interested in order to find the value of n, if we solve n from equation (1) we got:

$n=(\frac{z_{\alpha/2} \sigma}{ME})^2$ (2)

The critical value for 98% of confidence interval now can be founded using the normal distribution. And in excel we can use this formla to find it:"=-NORM.INV(0.01,0,1)", and we got $z_{\alpha/2}=2.33$ , replacing into formula (2) we got:

$n=(\frac{2.33(19)}{7})^2 =39.996 \approx 40$

So the answer for this case would be n=40 rounded up to the nearest integer

Which equation represents a line which is perpendicular to the line 5y-4x=-15 5y−4x=−15?

Lady bird [3.3K]

Y = -5/4x + b is the equation that represents a line that is perpendicular to the line 5y-4x=-15

If you want it in standard form, it is 5x+4y=-15

Find two positive numbers whose difference is 30 and whose product is 2584.

kvasek [131]

Answer:

$38$ and $68$ .

Step-by-step explanation:

Let $x$ be the smaller one of the two number.

$x$ must be a positive integer. The other number would be $(x + 30)$ .

The question states that the product of the two numbers is $2584$ . In other words:

$x\, (x + 30) = 2584$ .

Rearrange this equation and solve for $x$ :

$x^{2} + 30\, x - 2584 = 0$ .

The first root of this quadratic equation would be:

$\begin{aligned}x_{1} &= \frac{(-30) + \sqrt{30^{2} - 4 \times (-2584)}}{2} \\ &= \frac{(-30) + \sqrt{900 + 10336}}{2} \\ &= \frac{(-30) + \sqrt{11236}}{2} \\ &= \frac{(-30)}{2} + \sqrt{\frac{11236}{2^{2}}} \\ &= (-15) + \sqrt{2809} \\ &= (-15) + 53 \\ &= 38 \end{aligned}$ .
