Two angles of a triangle measure 120 and 40°.
What is the measure of the third angle of the triangle?
Answer: 20°
the measure of the third angle of the triangle is x ( 0 < x < 90)
because this is 3 angles in a triangle, we have:
120 + 40 + x = 180
⇔ x = 180 - 120 - 40
⇔ x = 20°

A(7/12.
b(-7/12

Answer:

Step-by-step explanation:
[tex]\frac{2}{3}[/tex] + (-[tex]\frac{5}{6}[/tex]) + [tex]\frac{3}{4}[/tex] = [tex]\frac{8}{12}[/tex] + (-[tex]\frac{10}{12}[/tex]) + [tex]\frac{9}{12}[/tex] = -[tex]\frac{2}{12}[/tex] + [tex]\frac{9}{12}[/tex] = [tex]\frac{7}{12}[/tex]
The records of a casualty insurance company show that, in the past, its clients have had a mean of 1.9 auto accidents per day with a variance of 0.0016 . The actuaries of the company claim that the variance of the number of accidents per day is no longer equal to 0.0016 . Suppose that we want to carry out a hypothesis test to see if there is support for the actuaries' claim. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test.
Answer:
H0: σ² = 0.0016 against the claim
H1: σ² ≠ 0.0016
Step-by-step explanation:
The claim is the alternative hypothesis . If we have the alternative hypothesis that variance is not equal to 0.0016. Then the null hypothesis would
H0: σ² = 0.0016 against the claim
H1: σ²≠ 0.0016
This is a two tailed test.
The null hypothesis is opposite to the claim stated. The claim is the alternative hypothesis.
By knowing the alternative hypothesis one can find the null hypothesis.
The claim is that the variance of the number of accidents per day is no longer equal to 0.0016.
The claim is H1: variance≠ 0.0016 or
H1= σ²≠ 0.0016
Therefore the null hypothesis is
H0: σ²=0.0016

You work 12 hours for $69. Find the rate per hour.
Maria worked 20 hours and was paid $157.80 before taxes. At this rate, how much is Maria paid per hour?
0 A $7.79
OB. $7.95
O C. $7.86
D. $7.89
The rate paid per hour for the given condition will be $7.89 per hour thus option (D) is correct.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
As per the given,
Total paid = $157.80
Total hours working = 20 hours
Rate of change = 157.80/20 = $7.89 per hour
Hence "The hourly wage for the specified circumstance will be $7.89.".

Which of the following is true? Group of answer choices Pie charts can generally be used instead of bar charts. Line charts are not used for cross-sectional data. Pyramid charts are generally preferred instead of column charts. Line charts are useful for visualizing categorical data.
Answer:
Pie charts can generally be used instead of bar graphs
Step-by-step explanation:
A pie chart can be used instead of a bar chart. A pie chart is an alternative to the bar chart. Both of these can be regarded as data visualization tools. The pie chart shoes us generally how several parts makes up a whole. While the bar chart uses rectangular bars to show us the proportion of each of the categories of data
The statement which is true among the given group of options is; Pie charts can generally be used instead of bar charts.
Data visualization toolsPie charts can be used as substitutes for bar charts. This stemmed from.the fact that both tools are data visualization tools.
On this note, pie charts can be used to replace the bar charts even though pie charts entails dividing the 360° angle in a circle in respective ratios.

Answer:
M AED = 32.5º
Explanation:
M AED = 1/2 x (113º - 48º) = 32.5º
This is an example of angles with vertex outside the circle and their arcs. The formula to find the measure of an angle with the vertex outside the circle is 1/2 x (difference of intercepted arcs), in this case it's 1/2 x (113º - 48º), which equals 32.5º.

For the arithmetic sequence beginning with the terms {5, 6, 7, 8, 9, 10...}, what is the sum of the first 17 terms
Answer: S = 221
Step-by-step explanation: An arithmetic sequence is a set of numbers in order, having the difference between one term and the next a constant.
The sum of an arithmetic sequence can be calculated as the following formula:
[tex]S=\frac{n}{2} [2a_{1}+(n-1)r][/tex]
where
n is how many terms to add
a₁ is the 1st term of the sequence
r is the constant
For the sequence above:
[tex]S=\frac{17}{2} [2(5)+(17-1)1][/tex]
[tex]S=\frac{17}{2}(26)[/tex]
[tex]S=17(13)[/tex]
S = 221
The sum of the first 17 terms of the arithmetic sequence {5,6,7,8,9,10...} is 221
