The formula F=95(K−273.15)+32 converts a temperature from kelvin K to degrees Fahrenheit
DENIUS [597]

F=95(K−273.15)+32

Switch the equation so that F is on the right side:

95(K−273.15)+32 = F

Use the distributive property:

95K + 95(-273.15) + 32 = F

95K - 25949.25 + 32 = F

95K - 25917.25 = F

Add 25917.25 to both sides:

95K = 25917.25 + F

Divide each term by 95:

K = 25917.25 / 95 + F/95


K = (25917.25 + F) /95

The National Assessment of Educational Progress (NAEP) gives a math assessment every year to 12th graders in the U.S. On the mat
amid [387]

Answer:

The correct answer is option 2.

Step-by-step explanation:

In this case we need to test whether young men nationwide have a mean score below 275 in the National Assessment of Educational Progress math assessment.

The hypothesis is defined as follows:

<em>H₀</em>: <em>μ</em> = 275 vs. <em>Hₐ</em>: <em>μ</em> < 275

The significance level of the test is <em>α</em> = 0.05.

The <em>p</em>-value of the test is computed as, <em>p</em>-value = 0.20.

Decision rule:

A small <em>p</em>-value (typically ≤ 0.05) specifies solid proof against the null hypothesis (<em>H₀</em>), so you discard the null hypothesis.

A large <em>p</em>-value (> 0.05) specifies fragile proof against the null hypothesis, so you fail to discard the null hypothesis.

<em>p</em>-value = 0.20 > <em>α</em> = 0.05.

The null hypothesis was failed to rejected at 5% level of significance.

Thus, it can be concluded that there is not enough evidence to conclude that the mean score is less than 275 for young men nationwide.

Thus, the correct answer is option 2.

Given that 2x - 11 find y when x is 7
Nikolay [14]

Answer:

y = 3

Step-by-step explanation:

(Assuming that 2x - 11 = y)

2x - 11 = y \\ 2(7) - 11 = y \\ 14 - 11 = y \\ 3 = y \\ y = 3

Which of the following are solutions to the equation below?
Karo-lina-s [1.5K]

There are several ways in which we could answer this question. My choice is to actually solve the given quadratic equation, x^2 + 4x + 4 = 12.

Note that x^2 + 4x + 4 is a perfect square. Thus,

x^2 + 4x + 4 = 12 is the same as (x+2)^2 = 12, so that

x+2 = plus or minus √3*√4, or plus or minus 2√3.

Thus, the two real, unequal roots are

x = -2 + 2√3 and x = -2 - 2√3. These correspond to answer choices C and E.
