What is the equation of the line in slope-intercept form?
Answer:
y = 1x - 80
Step-by-step explanation:
Formula: y = mx + b
m = slope
b = y-intercept (where the line intersects the y-axis)
m = rise over run or y/x
r/r = 10/10 = 1
b = -80
y = mx + b
y = 1x - 80 or y = x - 80 (same thing)
y = 1x - 80

A mother gives birth to a 6 pound baby. Every 2 months, the baby gains 5 pounds. If x is the age of the baby in months, then y is the weight of the baby in pounds. Find an equation of a line in the form y = mx + b that describes the baby's weight. Y = _____________________
Answer:
y=2.5x+6
Step-by-step explanation:
y= weight
6 is the weight that the baby is born so you would add it to the end making it the b
5 pounds every 2 months so 2.5 pounds every 1 month.
The linear equation model is y = 2.5x+6.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The slope-intercept form is y = mx+c, where the slope is m and the y-intercept is c.
Given that mother gives birth to a 6-pound baby. Every 2 months, the baby gains 5 pounds
We have to determine an equation of a line in the form y = mx + b that describes the baby's weight.
If x is the age of the baby in months, then y is the weight of the baby in pounds.
Since 5 pounds every 2 months
Therefore 2.5 pounds every 1 month.
We would add 6 at the end of the equation, which would result in the birth weight.
Thus, the linear equation model is y = 2.5x+6.

3 coins are tossed and two six sided dice are rolled what is the probablity of getting 3 heads. and an even number on the dice show your work for brainliest if its correct.
Answer:
1/32
Step-by-step explanation:
- if the even numvers of the every six-sided dice are: 2; 4; 6, then the probability of even number of one dice is 3/6=0.5.
- the probability of getting head of one coin is 0.5;
- the required probability of getting 3 heads and even number on the dice is:
0.5^³*0.5^²=0.125*0.25=0.03125 (or 1/32)

In a bag there are 3 red marbles, 2 yellow marbles, and 1 blue marble. what is the probability in simplest form of a yellow marble being selected on the first draw.
Answer:
The probability is 1/3, or in percent form, 33.3%.
Step-by-step explanation:
First, add up all the marbles. 3 plus 2 plus 1 equals 6 total marbles.
There are 2 yellow marbles out of 6 total marbles. Make it a fraction: 2/6.
Simplify the fraction by dividing by 2, to get 1/3, which is 33.3%.

How much water do you add to make 12% sugar syrup using 5g sugar.
Answer:
You know that 5 g of sugar form 12%. Let x g be the amount of water needed. The total amount of syrup will be x+5 g. Then
5 g - 12%,
x+5 g - 100%.
mathematically you can write a proportion;
5/x+5=12/100
=>500=12(x+5)
,500=12x+60
,12x=400,
x=440/12
=110/3
=36 2/3g of water36.66 grams of water is added to make 12% sugar syrup using 5g sugar.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Let the amount of water is added be 'x'.
Amount of sugar = 5 g
We need to make 12% of sugar syrup.
x grams of water is added to 5 g of sugar, to 12% of sugar syrup.
5/5+x=12/100
Apply cross multiplication
5×100=12(5+x)
500=60+12x
Subtract 60 from both sides
440=12x
Divide both sides by 12
x=36.66
Hence, 36.66 grams of water is added to make 12% sugar syrup using 5g sugar.

Please help me I’ve been stuck for hours
Answer/Step-by-step explanation:
Given that a and b are two corresponding sides of two similar figures, it follows that the ratio of their areas = a²/b².
We would use the above knowledge to solve the questions given as follows:
✔️The first pair similar of shapes:
Missing area = x cm²
Therefore,
x/9 = 8²/4²
x/9 = 64/16
x/9 = 4
Cross multiply
x = 4 × 9
x = 36 cm²
✔️The second pair similar of shapes:
Missing area = x cm²
Therefore,
x/240 = 8²/32²
x/240 = 64/1,024
Cross multiply
x*1,024 = 64*240
x*1,024 = 15,360
Divide both sides by 1,024
x = 15,360/1,024
x = 15 cm²
✔️The third pair similar of shapes:
Missing area = x cm²
Therefore,
x/40 = 3²/2²
x/40 = 9/4
Cross multiply
x*4 = 9*40
x*4 = 360
Divide both sides by 4
x = 360/4
x = 90 cm²

Steph makes 90\%90%90, percent of the free throws she attempts. She is going to shoot 333 free throws. Assume that the results of free throws are independent from each other. Let XXX represent the number of free throws she makes.
Find the probability that Steph makes exactly 111 of the 333 free throws.
Using the concept of binomial probability, the probability of making exactly 11 throws is [tex]6.073 \times 10^{-15} [/tex]
Recall :
P(x = x) = nCx * p^x * q^(n-x)p = probability of success = 0.9n = number of trials = 33q = 1 - p = 0.1The probability of making exactly 11 throws can be defined thus :
P(X = 11) = 33C11 * 0.9^11 * 0.1^22Using a binomial probability calculator :
P(X = 11) = [tex]6.073 \times 10^{-15} [/tex]
Therefore, the probability is [tex]6.073 \times 10^{-15} [/tex]
