Answer:
Michael is within the speed limit regulation he won´t get any ticket
Nico is over speed limit then he should be ticket
Step-by-step explanation:
Case A conditions in a freeway evening average speed 75 MPH the
standard deviation is 7 MPH
Then according to new policy 75 + 7* ( 1,5 ) = 75 + 10,5 = 85,5 MPH
Michael is driving at 84 MPH then he has no problem at all
Case B conditions in a major street average speed 43 MPH the standard deviation is 4 MPH
According to the new policy 43 + 4 *(1,5) = 43 + 6 = 49 MPH
Nico is driving at 50 MPH then Nico will be ticket

The farmer decided that he ordered enough planks for an arena that measured 115 1/4 ft by 63 1/2 ft. Is he correct? Explain.
What questions do you need to answer this question? Please help
Answer:
The question we need to answer is what is the perimeter of the arenaStep-by-step explanation:
The question we need to answer is what total length of plank did the farmer ordered for the arena.
to solve for the length of plank to cover the arena we need to solve for the perimeter of the arena.
given data
length L= 115 1/4 ft = 115.25ft
width W= 63 1/2 = 63.5ft
perimeter= 2L+2W
perimeter= 2(115.25)+2(63.5)
perimeter= 230.5+127
perimeter= 357.5ft
This means that the farmer ordered a total length of 357.5ft of plank

[tex]b = 180 - 130 = 50[/tex]
i think this is the answer
Intro:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
<b and 50° are vertical angles so that means they are congruent. So that means <b is 50.
<c and 50° are supplementary angles which means when you add them you should get 180. So if do 180 - 50 we will get 130. So that means <c is 130°.

7. Given a right triangle as shown below, use a calculator to estimate the length of the
missing side to the nearest tenth of a centimeter
Answer:
D. 11.6 cm
Step-by-step explanation:
The missing length of the right angled triangle can be calculated using Pythagorean Theorem as shown below:
[tex] c^2 - b^2 = a^2 [/tex]
Where,
a = x cm
b = 11 cm
c = 16 cm
Thus:
[tex] 16^2 - 11^2 = x^2 [/tex]
[tex] 256 - 121 = x^2 [/tex]
[tex] 135 = x^2 [/tex]
[tex] \sqrt{135} = \sqrt{x^2} [/tex]
[tex] \sqrt{135} = x [/tex]
[tex] 11.61895 = x [/tex]
[tex] x = 11.6 cm [/tex] (nearest tenth)

R is the midpoint of segment PS. Q is the midpoint of segment RS. P is located at (8,10), and S is located at (12,-6). What are the coordinates of Q
Answer:
(10,2)
Step-by-step explanation:
To find the midpoint you have to:
Add both "x" coordinates then divide by 2. 12+8=20 20/2=10
Add both "y" coordinates then divide by 2. 10+(-6)=4 4/2=2
Enter the coordinates where P' should be.

The mean mass of the 15 players in a rugby team is 85.2kg the mean mass of the team plus a substitute is 85.4kg what is the mass of the substitute ?
Answer:
88.4 kg
Step-by-step explanation:
Since we are given the mean we will need to multiply the mean by how many players there are on the team to find the total mass. (The second mean will be multiplied by 16 because it is the number of players on the team plus the substitute)
85.2 x 15 = 1,278
85.4 x 16 = 1,366.4
Subtract the first mass from the second because this will remove the mass of the 15 other players.
1366.4 - 1278 = 88.4
88.4 kg is the mass of the substitute.
On a lunch counter, there are 3 oranges, 5 apples, and 2 bananas. If 3 pieces of fruit are selected, find the probability that 1 orange, 1 apple, and 1 banana are selected (does not have to be in that order).
Answer:
[tex]Probability = \frac{1}{24}[/tex]
Step-by-step explanation:
Given
[tex]Oranges = 3[/tex]
[tex]Apples = 5[/tex]
[tex]Banana = 2[/tex]
[tex]Total = 10[/tex]
Required
Determine the probability of 1 orange, 1 apple and 1 banana
Since, order is not important:
[tex]Probability = P(Orange) * P(Apple) * P(Banana)[/tex]
[tex]Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}[/tex]
The difference in the numerator is as a result of picking the fruit without replacement
[tex]Probability = \frac{30}{720}[/tex]
[tex]Probability = \frac{1}{24}[/tex]
Probability is simply how likely something is to happen.
The probability of 1 orange, 1 apple, and 1 banana are [tex]\frac{1}{24}[/tex]
On lunch counter,
Number of oranges = 3
Number of apples = 5
Number of bananas = 2
If 3 piece of fruit is selected then, probability of 1 orange, 1 apple and 1 banana
[tex]=\frac{3}{10}*\frac{5}{9} *\frac{2}{8} \\\\=\frac{30}{720}\\\\=\frac{1}{24}[/tex]
Therefore, the probability of selecting 1 orange, 1 apple, and 1 banana are [tex]\frac{1}{24}[/tex]

can u solve this please? 18x-2 = 17x +2
Answer:
Step-by-step explanation:
18x-2 = 17x +2
⇒18x-17x - 2 = 2
⇒x - 2 = 2
∴ x = 4
Answer:
x=4
Step-by-step explanation:
18x-2=17x+2
step 1: isolate the x by subtracting 17x from both sides
18x-2-17x=17x+2-17x
x-2=2
then add 2 to both sides
x-2+2 = 2+2
x=4
