The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is [tex]a=-15b-5[/tex]
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
[tex]a-[/tex][tex]a_{1}[/tex][tex]=x[b-b_{1}][/tex]
Where we will consider (1/3,0) = [tex]a-a_{1}[/tex] and (0,-5) = [tex]b-b_{1}[/tex]
that is 1/3 = [tex]a[/tex], 0 = [tex]a_{1}[/tex] and
0 = [tex]b[/tex], -5 = [tex]b_{1}[/tex]
[tex]x[/tex] refers to the slope of line (take any variable)
Now for finding the value of [tex]x[/tex],
[tex]x=a-a_{1}/b-b_{1}[/tex]
inserting the values,
[tex]x=[0-[-5]]/[0-1/3]\\x= -15[/tex]

Step-by-step explanation:
The difference beteen 9.2 ounces and 8.1 ounces is 1.1 ounces
and the difference in price is .49
so 1.1 ounces cost .49
$ .49 / 1.1 oz = $ .445 per ounce
Then Reid's bowl should cost 7.8 oz * $ .445 / oz = $3.47

( 13m).
Area of rectangle= Length × Width
= 11m × 3m
= 33m²
Area of triangle= ½ × base × height
To find the height= 13m - 11m = 2m
= ½ × 3 × 2
= ½ × 6
= 3m²
Area of the polygon= 33m² + 3m² = 36m²

Answer:
22 - x - 30)
Step-by-step explanation:
) 30 + x - 2^2 can be rewritten as: 30 + x - 4 = 26 + (x - 30) = -(30 - x) + 26 = -(x - 22) - 4 = -(22 - x) - 4 Therefore, 30 + x - 2^2 can be rewritten as - (. b) Using the result obtained in part (a): 30 + x - x^2 = 30 + x - x^2 + 22 - x - 30 - 22 + x + 30 = -(x^2 - x - 30) - (22 - x - 30) = -(x^2 - x - 30) - (-x - 8) = -(x - 6)(x + 5) - (-x - 8) = (x - 6)(-x - 5) + (x + 8) = (x - 6)(-x - 5) + 8 + 5(x - 6) = (x - 6)(5 - x) + 5(2 - x) = (x - 6)(x - 5) - 5(x - 2) Hence, the fully factorised form of the quadratic expression 30 + x - x^2 is (x - 6)(x - 5) - 5(x - 2
A juice company gives prizes to anyone finding specially marked caps on its bottles. You and your friends buy 60 bottles of juice. You find 4 of the bottles have a winning cap. What is the experimental probability of winning a prize in the contest? Express your answer as a fraction in simplest form.
Answer:
[tex]\Huge \boxed{ \text{$\frac{1}{15}$}}[/tex]
Step-by-step explanation:
Experimental probability is the probability calculated by performing actual experiments and observing the outcomes. In this case, the experiment is buying juice bottles and checking if they have a winning cap.
You and your friends bought 60 bottles of juice.You found 4 of them had winning caps.To find the experimental probability, we need to divide the number of winning caps (favourable outcomes) by the total number of bottles (possible outcomes).
The experimental probability can be expressed as a fraction:
[tex]\frac{ \text{ \huge Number of Winning Caps}}{\text{ \huge Total Number of Bottles}}[/tex]
Now, let's plug in the numbers you provided:
[tex]\huge \text{ $\frac{4}{60}$}[/tex]
To simplify this fraction, we need to find the greatest common factor (GCF), of the numerator (4) and the denominator (60) and then divide both by the HCF. The HCF of 4 and 60 is 4. So, we divide both the numerator and the denominator by 4:
[tex]\huge \text{ $\frac{4 \div 4}{60 \div 4}$= $\frac{1}{15}$}[/tex]
So, the experimental probability of winning a prize in the contest is [tex]\frac{1}{15}[/tex]. This means that, based on your experiment, there is 1 chance in 15 of finding a winning cap when buying a bottle of juice.
________________________________________________________
Answer: hope this helps ♡
The experimental probability of winning a prize in the contest is 1/15.
Step-by-step explanation:
We want to write the probability of winning a prize in the contest.
Here, the number of bottles with a winning cap is 4 and the total (number of bottles) is 60.
Hence, we will write that the experimental probability of winning a prize in the contest is 4/60.
4/60 simplified is: [tex]\frac{4}{60}=\frac{4 divided by 4}{60dividedby4} = \frac{1}{15}[/tex]

A rectangle field has an area of 300 square meters and a perimeter of 80 meters. What are the length and width of the field?
Answer:
l + w = 40, lw = 300
l(40 - l) = 300
40l - l² = 300
l² - 40l + 300 = 0
(l - 30)(l - 10) = 0
l = 30, w = 10
The length of the field is 30 meters, and the width of the field is 10 meters.

If the probability of no rain tomorrow is 30%, what is the probability that it will rain tomorrow? Express your answer as a percent.
Answer:
70%
Step-by-step explanation:
Since the probability of no rain tomorrow is 30%, that means 30% of the probability is taken up by the chance of no rain.
Since the total probability always adds up to 100%, that means the remaining 70% of the probability must be for rain.'
So the probability that it will rain tomorrow is 70%.
You can verify this with a probability tree diagram:
Total Probability = 100%
No Rain - 30%
▼
More Likely event
▲
Rain - 70%
Since the chance of no rain is 30%, that leaves 70% for the chance of rain.
The probability that it will rain tomorrow is 70%.
What is probability?
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.
Given the problem, we need to find the probability that it will rain tomorrow.
Since, the probability of no rain tomorrow is 30%, the probability that it will rain tomorrow is 100% - 30% = 70%.
Hence, the probability that it will rain tomorrow is 70%.
