Answer:
1) 1/3 2a)2/5 2b)1/2 2c)9/20
Step-by-step explanation:
1) A fair die has 6 sides (1,2,3,4,5,6) so there are 2 sides that are greater than 4. Probability is chance of occurance/total chances so 2/6 which simplifies to 1/3
2) The set is (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19, 20) The prime numbers in that set are (2,3,5,7,11,13,17,19)
a)So the probability that a prime number is picked is 8/20 which simplifies to 2/5
b) The odd numbers are (1,3,5,7,9,11,13,15,17,19) so probability of odd is 10/20 which simplifies to 1/2
c) The single digit numbers are (1,2,3,4,5,6,7,8,9) so the probability is 9/20

Answer:
2 times length of AB
Step-by-step explanation:
Given
[tex]AB =50\%[/tex]
Required
Length of line with 100%
To get the length of line segment that is 100%, simply multiply AB by 2
i.e.
[tex]2 * AB =2 * 50\%[/tex]
[tex]2 AB =100\%[/tex]
Assume AB = 5cm (at 50%). The length at 100% will be 10cm i.e. 2 * 5cm

What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Bananas are on sale for $0.39 per pound. Mr. Schurter bought 3 x 3 /4 pounds of bananas.
Cost of 1 pound of banana = $0.39
Let x be the cost of 3 × 3/4 pounds of banana.
3 × 3/4 pounds = 9/4 pounds
By proportional concept,
1 : 0.39 = 9/4 : x
1 / 0.39 = 9/4 / x
Cross multiplying, we get,
1 × x = (9/4) × 0.39
x = 3.51 / 4
x = 0.8775
Hence the cost of 3 × 3/4 pounds of banana is $0.8775.

C
Step-by-step explanation:
4 is the y-intercept and 3 is the slope making the answer C.
As per the data the graph (A) represents the graph of the function f(x) = 3x+4 option (C) is correct.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of the function:
f(x) = 3x + 4
Let's plug x = 0
f(0) = 4
Let's plug x = 1
f(1) = 7
Let's plug x = -1
f(-1) = 1
Thus, as per the data above the graph (C) represents the graph of the function f(x) = 3x+4 option (C) is correct.

Which equation is a linear function
Answers
Answer:
[tex]y=\frac{x}{2} -5[/tex]
Step-by-step explanation:
Linear functions are those whose graph is a straight line.
A linear function has the following form: [tex]y=f(x)=a+bx[/tex]
A linear function has one independent variable and one dependent variable.
The independent variable is x and the dependent variable is y.
The degree of a linear equation must be 0 or 1 for each of its variables.
1. The degree of the variable y is 1 which means it is not linear.
2. The degree of the variable y is 1 and the degree of variable x is 1 so it is linear.
3. The degree of the variable y is 1 and the degree of the variable x is 2 so it is not linear.
4. The degrees of the variable violates the linear equation definition so it is not linear.

Answers
Answer:
√41
Step-by-step explanation:
The distance formula is expressed as;
D = √(y2-y1)²+(x2-x1)²
D = √(4-9)²+(-1+5)²
D = √(-5)²+4²
D = √25+16
D = √41
Hence the required distance between F and J is √41

Determine the area of the figure shown. Note that each square unit is one unite in length
Answers
Answer:
74 units squared
Step-by-step explanation:
we know that the area of a square or rectangle is A = L × w
so we should just separate the object into it's individual rectangles/squares, solve for their areas, then add them together.
so I'll start with the middle square its length is 8 and width is 8 too.
A = 8 × 8
A = 64
now we'll move on to the other small ones to the side.
the one on the right side it's length is 2 and width is 2.
A = 2 × 2
A = 4
and then the last one on the left, Length is 3, width is 2.
A = 2 × 3
A = 6
now we'll add up all of the areas to get the total area.
Total = 64 + 4 + 6
Total = 74 units squared

80% fewer cars on the road. How many cars were on the road in March
2020 every hour in Los Angeles, after the 80% reduction?
Answers
Answer:
Number of cars on road in 2020 = 35,400 car
Step-by-step explanation:
Given;
Number of cars on road = 177,000
Decrease in cars on road in 2020 = 80%
Find:
Number of cars on road in 2020
Computation:
Number of cars on road in 2020 = Number of cars on road[1 - Decrease in cars on road in 2020]
Number of cars on road in 2020 = 177,000[1-80%]
Number of cars on road in 2020 = 177,000[1-0.80]
Number of cars on road in 2020 = 177,000[0.20]
Number of cars on road in 2020 = 35,400 car
