The measure of an angle is 2.8.what is the measure of its complementary angle
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units

In a football game, one team makes 5 plays. The result of those plays are: gain of 7 yards, gain of 2 yards, loss of 5 yards, loss of 23 yards, gain of 16 yards. What is the overall gain or loss of all 5 plays?
Answer: Loss of 3 yards
Step-by-step explanation:
The overall gain or loss of all 5 plays will be gotten by adding all the results of the plays given and this will be:
= 7 + 2 - 5 - 23 + 16
Collect like terms
= 7+2+16-5-23
= 25 - 28
= -3
The overall loss of all 5 plays will be -3 yards or loss of 3 yards

A bag contains 6 white marblesw and 4 black marbles.a marble is drawn from the bag and then a second marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw and another white marble on the second draw
Answer:
60.5%
Step-by-step explanation:
60% white, 40% black
The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

A track is 400 yards around how many full laps does tyler need to run if he wants to run atleast 2 milies
Answer:
17.6 laps
Step-by-step explanation:
Total distance to be covered = 2 miles
distance coved in each lap = 400 yards
We know that 1 mile = 1760 yards
therefore, 4 miles will make = 4×1760
= 7040 yards.
Number of laps to be taken
= Total distance to be covered ÷ distance coved in each lap
= 7040/400 = 17.6 laps
Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.
