Step-by-step explanation:
The pair members cannot be multiplied. Look at the last numbers that are prime starting with eleven
What are you going to pair these primes with
11 13 17 19
So they must be added (or maybe subtracted).
1 19
2 18
3 17
4 16
5 15
6 14
7 13
8 12
9 11
and 20 which no matter how you do this, there will be 1 card left over.
Each of them adds to 20 so the LCM is 20

An engineer wants to determine how the weight of a gas-powered car, x, affects gas mileage, y. The accompanying data represent the weights of various domestic cars and their miles per gallon in the city for the most recent model year. Complete parts (a) through (d) below.

Is the miles per gallon of this car above average or below average for cars of this weight? The estimated average miles per gallon for cars of this weight is ( ) miles per gallon. The miles per gallon of this car is average for cars of this weight.
Answer:
y= 0.007x- 4.945
The estimated average miles per gallon for cars of this weight is (20.829 or 21 ) miles per gallon.
The miles per gallon of this car below (18 < 20.829) the average for cars of this weight.

∑y²=4075; ∑y=199; ∑x²= 116,406,174 ; ∑x=33,844 ; ∑xy=659,808
b= n∑XY - (∑X)(∑Y)/ n∑X² - (∑X)²
b=(10) (659,808) - (33,844)(199)/ 10 (116,406,174) - 1,145,416,336
b=6,598,080- 6,734,956/ 1,164,061,740 -1,145,416,336
b=136,876/18,645,404
b= 0.007341
a= Y`- bX`
a= 19.9- (0.007341) (3384.4)
a= 19.9 -24.845
a=-4.945
Y^= -4.945+ ( 0.007341) X
y= 0.007x- 4.945
Putting the values
y= 0.007x- 4.945
18 = 0.007(3511) - 4.945
18< 20.829
The estimated average miles per gallon for cars of this weight is (20.829 or 21 ) miles per gallon.
The miles per gallon of this car below (18 < 20.829) the average for cars of this weight.

Help worth 10 points I need the whole area of the shape
Answer:
1,736km^2
Step-by-step explanation:
Answer:
2,352 km^2
Step-by-step explanation:
So there is a square and 4 triangles.
You first, find the area of the square.
You then get: 35 x 48 = 1,680
Then you need to add the triangles.
Because we have 2 triangles on each side the area formula of a triangle in which is 1/2 times by the base and height can be solved by just B * H.
Doing that you can get: 48 * 7 = 336
Because you have 2 triangles, the final area results in:
1,680 + 336 * 2 = 2,352

The required measure of x in the triangle QRS is given as x = 8.
What are Similar triangles?Similar triangles are triangles that have the same shape but possibly different sizes. More formally, two triangles are similar if their corresponding angles are congruent (equal in measure), and their corresponding sides are in proportion (have the same ratio).
Here,
Since Triangle QRS is similar to triangle QXY.
The property of similar triangle states that the sides of both the triangle will be proportional to each other.
So,
QR/QX = QS/QY
Substitute the value in the above expression,
6/18 = x/ [x + 16]
Simplifying the above expression,
x + 16 = 3x
x = 8
Thus, the required measure of x in the triangle QRS is given as x = 8.

Find the measure of angle x. Hint. The sum of the measures of the angles in a triangle is 180 degrees.
A. 6°
B. 90°
C. 180°
D. 86°
Answer:
D
Step-by-step explanation:
Básicamente sumas esos 2 y se lo restas a 180.
Answer:
D. 86
Step-by-step explanation:
since the angles of a triangle add up to equal 180, all you have to do is add the angles you know and then find the one you don't by subtracting it from 180.
this is how it looks mathematically:
180=26+68+x
180=94+x
180-94=x
x=86

Solve the system of equations by substitution. * -8x + 2y = 4 y = 4x + 2
Answer:
Step-by-step explanation:
-8x + 2y = 4
y = 4x + 2
Put the value of y into the first equation
-8x + 2(4x + 2) = 4 Remove the brackets
-8x + 8x + 4 = 4 The 8xs cancel out.
4 = 4 But this is useless. There is no single solution

A fish tank at a hatchery contains 25 fish. The histogram below shows the number of fish organized by weight rounded to the nearest whole ounce. One fish is taken from the tank at random. What is the probability the fish weighs at least 12 ounces?
Answer:1/5
Step-by-step explanation:
The probability the fish weighs at least 12 ounces is 1/5. Probability has several uses in games.
What is probability?The chances of an event occurring are defined by probability. Probability has many uses in games, in business to create probability-based forecasts.
The given data in the problem is;
A fish tank at a hatchery contains = 25 fish
Fish weighs at least 12 ounces=5
probability the fish weighs at least 12 ounces=?
The probability the fish weighs at least 12 ounces is ;
[tex]\rm P = \frac{Favourable \ event }{Total\ event} \\\\ \rm P = \frac{5}{25} \\\\ P=\frac{1}{5}[/tex]

City A and City B are 540 miles apart on a map. The scale on the map is 1inch:60 miles. How many inches apart on the map should City A and City B measure. Explain how you would solve this problem. What would the final answer be?
Answer: 9 inch
Step-by-step explanation:
Given
Distance between city A and city B is 540 miles
Scale on the map is 1 inch: 60 miles i.e. 1 inch on the map is equivalent to 60 miles in the real situation
suppose the distance between city A and B on the map is x
[tex]\therefore \dfrac{1}{60}=\dfrac{x}{540}\\\\\Rightarrow x=\dfrac{540}{60}=9\ in.[/tex]
Therefore, the distance between city A and B is 9 in.

If a triangle has a side length of 5 inches and another side length of 7 inches, which of the
following choices for the third side length will make a triangle?
a. 1 inch
b. 2 inches
c. 6 inches
d. 13 inches
Answer:
d. 13 inches
Step-by-step explanation:
When we need to solve the side length and length of triangles, we need to remember one thing.
Coming to a right triangle, there are two short sides and one long side, and the two short sides need to add up to something less than the one long side.
Therefore, since we know our two short sides, add them :
7in. + 5in.
= 12in.
Looking at the answers, we can point out that d. is greater than 12 inches, therefore making it the correct answer.
