The second of two numbers is 3 less than twice the first. Their sum is 36. Find the numbers.

swat32

<span>The first number = x
The </span>second number = 2x-3

x + 2x-3 = 36
3x = 36+3
3x = 39
x = 39/3
x = 13

The first number = x = 13
The second number = 2x-3 = 2*13 - 3 = 26 - 3 = 23

Descent, Inc., produces a variety of climbing and mountaineering equipment. One of its products is a traditional three-strand cl

Rainbow [258]

Solution :

Assuming $\sigma_1^2=\sigma_2^2$

We have to test

$H_0:\mu_1=\mu_2$

Against $H_a: \mu_1 \neq \mu_2$

Level of significance, $\alpha = 0.05$

$s_p=\sqrt{\frac{(n_1-1)s_1^2+ (n_2-1)s_2^2}{n_1+n_2-2}}$

$s_p=\sqrt{\frac{(25-1)(425)^2+ (20-1)(415)^2}{25+20-2}}$

= 420.6107

Under $H_0$ , the t-statistics is as follows:

$t=\frac{(\overline{x_1} - \overline{x_2})}{s_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}} \sim$ $\text{t with }(n_1+n_2-2) \ DF$

$t=\frac{(7200-7087)}{(420.6107)\sqrt{\frac{1}{25}+\frac{1}{20}}}$

= 0.90

DF = (25 + 20 - 2)

= 43

P-value of the test = 0.375

Since the p value is more than 0.05, we fail to reject our null hypothesis.

There is no difference between then mean tensile strength of the ropes that is produced in the Bozeman and Challis.

Larissa argued that since log2(2) = 1 and log2(4) = 2, then it must be true that log2(3) = 1.5. Is she correct?

mestny [16]

Answer:

$2^{1.5} = 2.8284$ . This means that Larissa is not correct.

Step-by-step explanation:

To solve logarithms, we have to consider the following:

$\log_{a}(b)$ = c means that $a^{c} = b$ .

So, for example:

$log_{2}(2) = 1$ because $2^{1} = 2$ .

$log_{2}(4) = 2$ because $2^{2} = 4$ .

If $2^{1.5} = 3$ , then Larissa is correct. However, $2^{1.5} = 2.8284$ . This means that Larissa is not correct.

Which characteristic does the graph display?

Leto [7]

If the factors of the polynomial are (x - 2), (x), and (x + 2). Then the equation of the graph will be (x³ - 4x).

<h3>What is the equation of the graph?</h3>

The solutions of the graph are 2, 0, and negative 2.

Then the factor can be given as

(x - 2), (x), and (x + 2)

Then the product of the factor will be given below.

(x - 2) × (x) × (x + 2)

x (x² - 4)

x³ - 4x

More about the equation of the graph link is given below.
