The correct answer is 103 degrees (180-77) Since there is a line exactly in the half of the circle and we know that one portion is 77° so the remaining portion must be the difference of a half circle which is 180° minus the 77°.

Emily and Hunter tracked the average temperature in their city for the past 8 days. They recorded their temperature findings in
lions [1.4K]

Answer:

The mean absolute deviation = 3.5°F

Step-by-step explanation:

The sum of the given temperatures, ∑T, is found as follows;

∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F

The number of days, n, over which the temperature was tracked = 8 days

Therefore, the mean, \bar x, of the data set = ∑T/n = 480°F/8 = 60°F

The mean absolute deviation is given by the following formula;

Mean \ absolute \ deviation = \frac{\sum \limits_{i = 1}^{n} \left | x_i - \bar x \right | }{n}

Therefore, we have;

66 - 60 = \left | 6\right | = 6

57 - 60 = \left | -3\right | = 3

61 - 60 =  \left | 1\right | = 1

65 - 60 =  \left | 5\right | = 5

54 - 60 =  \left | -6\right | = 6

62 - 60 =  \left | 2\right | = 2

59 - 60 =  \left | -1\right | = 1

56 - 60 =  \left | -4\right | = 4

The mean absolute deviation is therefore;

The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.

Which function below is the inverse of f(x)=7x-1/2
Margaret [11]

We write f(x) in terms of y I.e y=7x-1/2.

Fractions are sometimes ambiguous, we eliminate the fraction by multiplaying the entire function by 2.so as to get 2y=14x-1.

Make x the subject, x=2y+1/14,

Thus the inverse f(x)=2x+1/14

A cell phone plan costs (c) $214.80 for 6 Months (m). Write a equation for this proportional relationship.
Sergeeva-Olga [200]
$214.80c x 6m = x.
Because you multiply the cost of the phone by the amount of months you're paying for it i think.

a bag of 10 marbles contains seven striped Marbles and 3 black marbles in the first event Mark draws a striped marble he does no
Illusion [34]

The probabability that he will obtain a black marble is as follows.

Using the first event, since there are 7 striped marbles and there's a total of 10 marbles, the probability must be as follows:

P=\frac{7}{10}

For the next three event, since there are no replacements, the denominators of each factor will be subtracted by 1. Thus, we have the following:

P=\frac{7}{10}\cdot\frac{\square}{9}\cdot\frac{\square}{8}\cdot\frac{\square}{7}

Since one striped marble is already taken in the first event, there must be 6 striped marbles left in the second event, and 5 on the third event. As for the fourth event, there are 3 black marbles based from the given. Thus, the probability up until the fourth event is as follows:

P=\frac{7}{10}\cdot\frac{6}{9}\cdot\frac{5}{8}\cdot\frac{3}{7}

Finally, to find the probability that he will select a black marble on the fifth event, the fifth factor must have a denominator of 6 since 4 marbles were already taken out in the first 4 events. On the other hand, the numerator must be 2 since one black marble is taken out on the 4th event.

Thus, simplifying the probability, we have the following:

P=\frac{7}{10}\cdot\frac{6}{9}\cdot\frac{5}{8}\cdot\frac{3}{7}\cdot\frac{2}{6}=\frac{1}{24}

Therefore, the probability must be 1/24.
