Area = (1/2)(base)(height)
48 = (1/2)(12+12)(height)
48 = (1/2)(24)(h)
48 = 12h
h = 48/12
h = 4 units

Geometry. What is the measure of segment x rounded to the nearest hundredths place? Check picture below also.

Scorpion4ik [409]

Answer:

D. 21 ft

Step-by-step explanation:

We need to use Power of Points, which basically says that for intersecting chords in a circle (see attachment), a * b = c * d.

Here, we can say that a = x, b = 6, c = 7, and d = 18. Then, we have the equation:

ab = cd

x * 6 = 7 * 18

6x = 126

x = 21

Thus, x is 21 ft.

Hope this helps!

A streaming music site changed its format to focus on previously unreleased music from rising artists. The site manager now want

nika2105 [10]

Answer:

D) The manager should fail to reject the null hypothesis; there is not enough evidence to conclude that the number of unique daily listeners has changed.

Step-by-step explanation:

The scenario indicates the null hypotheses and alternative hypotheses are

Null hypotheses: The number of unique daily listeners hasn't changed.

Alternative hypotheses: The number of unique daily listeners has changed.

The null hypothesis is rejected if the calculated p-value is less significance level.

We are given that p-value is 0.0743 and confidence level=0.95.

Significance level =α=1-0.95=0.05.

As we can see the p-value is greater than significance level, so, we fail to reject the null hypotheses at 5% significance level.

Thus, we conclude at the 95% confidence level that the manager should fail to reject the null hypothesis; there is not enough evidence to conclude that the number of unique daily listeners has changed

The tempeture of chicken soup is 192.7 degrees F. As it cools the tempeture of the soup decreases 2.3F per minute.

IrinaK [193]

Answer:

Step-by-step explanation:

To find the answer to Part A, we can turn this into a simple equation:

192.7 - (2.3 times 25) = <em>temperature, </em>the missing value.

So therefore, after 25 minutes pass, the temperature is equal to

192.7 - 57.5, or:

135.2 = Answer to Part A.

Now, onto Part B. We can use <u>another</u> equation!

192.7 - 2.3x = 100.7

Now, we must solve the given equation, first by taking 100.7 from each side:

192.7 - 2.3x = 100.7

-100.7 -100.7

We are now left with: 92 - 2.3x = 0 - we must now add 2.3x to 2.3x and 0, giving us this:

92 = 2.3x, which is equivalent to 920 = 23x, if that is what you prefer to solve.

To give us our missing value (x), we can divide 920 by 23, giving us: x = 40. This is the answer to Part B: 40 minutes.

I hope this was really helpful! Tell me if you need any more help.

Which ordered pair represent a function

sweet [91]

Answer:

The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. The second example is not a function, because it contains the ordered pairs (1,2) and (1,5).

Hope this helps you with your question.
