Answer:

x = ± 2.45

Step-by-step explanation:

Given

8x² - 48 = 0 ( add 48 to both sides )

8x² = 48 ( divide both sides by 8 )

x² = 6 ( take the square root of both sides )

x = ± \sqrt{6} = ± 2.45 ( nearest hundredth )

circle F is intersected by line HI and IJ and the measurement of angle HIJ is 101 degrees. what is the measurement of arc HJ
Colt1911 [192]
To solve this problem, you need to use the Exterior Angle (Out) equation which for this problem would be \frac{281-x}{2}=101. After correctly solving the problem with this equation, you will figure out that the answer is 79.

mHJ= 79°

Hope this helped :)

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 47.047.0 and
alisha [4.7K]

Answer:

0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is between c and d is given by the following formula

P(c \leq X \leq d) = \frac{d - c}{b-a}

For this problem, we have that:

a = 47, b = 57, c = 51.5, d = 51.75. So

P(c \leq X \leq d) = \frac{d - c}{b-a}

P(51.5 \leq X \leq 51.75) = \frac{51.75 - 51.5}{57 - 47} = 0.025

0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.
