Determine whether each equation represents a proportional relationship
1) y = 2x + 4
2) y = 2x
Answer:
(1) does not represent a proportional relationship, but (2) does.
Step-by-step explanation:
(1) y = 2x + 4 has a nonzero y-intercept, so it is not a proportional relationship.
(2) y=2x is a proportional relationship. It is of the form y=kx, where k is the constant of proportionality.
the sum of two numbers is 24 and there quotent is 3
Answer:
36 and -12
Step-by-step explanation:
One of the numbers is x then the second number will be 24-x
[tex]\frac{x}{24-x} = 3[/tex]
x = 72 - 3x
x = 36
therefore the second number -12

1 Imagine you throw three hoops over these cones
Add together the number of each
cone you get a hoop on.
You have three throws a turn.
What different totals can you
make on each turn?
30
90
40
Answer:
10 different total we can make.
Step-by-step explanation:
Consider the provided information.
It is given that we have three hoops and three cones of numbers 30, 40 and 90.
We are assuming that if we throw a hoop, it always falls on a cone.
Then the different totals are shown below:
If all three hoops fall on the same cone.
1) 30+30+30=90
2) 40+40+40=120
3) 90+90+90=270
If two out of three hoops fall on the same cone.
4) 30+40+40=110
5) 30+90+90=210
6) 40+30+30=100
7) 40+90+90=220
8) 90+30+30=150
9) 90+40+40=170
If all the hoops fall on the different cone.
10) 30+40+90=160
Hence, 10 different total we can make.

Answer:
[tex]m = -\frac{2}{5}[/tex] ---- slope
[tex]y = -\frac{1}{3}[/tex] --- y intercept
Step-by-step explanation:
Given
The attached table
Required
Calculate the slope and y intercept
First, we need to calculate the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
From the table, the following relationships exist:
[tex](x_1,y_1) = (-\frac{3}{4},-\frac{1}{30})[/tex]
[tex](x_2,y_2) = (\frac{1}{4},-\frac{13}{30})[/tex]
So, the expression for calculating slope becomes:
[tex]m = [-\frac{13}{30} - (-\frac{1}{30})] / [\frac{1}{4} - (-\frac{3}{4})][/tex]
[tex]m = [-\frac{13}{30} +\frac{1}{30}] / [\frac{1}{4} +\frac{3}{4}][/tex]
Take LCM
[tex]m = [\frac{-13+1}{30}] / [\frac{1+3}{4}][/tex]
[tex]m = [\frac{-12}{30}] / [\frac{4}{4}][/tex]
[tex]m = [\frac{-12}{30}] / 1[/tex]
[tex]m = \frac{-12}{30}[/tex]
[tex]m = \frac{-2}{5}[/tex]
[tex]m = -\frac{2}{5}[/tex]
To calculate the y intercept:
x must be 0. i.e.
[tex]x = 0[/tex]
So, we have:
[tex](x_1,y_1) = (-\frac{3}{4},-\frac{1}{30})[/tex]
[tex](x_2,y_2) = (0,y)[/tex]
[tex]m = -\frac{2}{5}[/tex]
Substitute these values in:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]-\frac{2}{5} = [y - (-\frac{1}{30})] / [0- (-\frac{3}{4})][/tex]
[tex]-\frac{2}{5} = [y +\frac{1}{30}] / [0+\frac{3}{4}][/tex]
[tex]-\frac{2}{5} = [y +\frac{1}{30}] / [\frac{3}{4}][/tex]
Multiply through by 3/4
[tex]-\frac{2}{5}*\frac{3}{4} = y +\frac{1}{30}[/tex]
[tex]-\frac{6}{20} = y +\frac{1}{30}[/tex]
[tex]-\frac{3}{10} = y +\frac{1}{30}[/tex]
Collect Like Terms
[tex]y = -\frac{3}{10}-\frac{1}{30}[/tex]
[tex]y = \frac{-9-1}{30}[/tex]
[tex]y = \frac{-10}{30}[/tex]
[tex]y = \frac{-1}{3}[/tex]
[tex]y = -\frac{1}{3}[/tex]

To make 100g of jam need 42g cherries, 12g of blackberries and the rest should be sugar.what is the ratio of blackberries to sugar? Give your answer in it's simple from
Answer:
6:23 or 6/23
Step-by-step explanation:
100 g total
42 g of cherries
12 g of blackberries

You roll two number cubes.
Let event A = The number rolled on the first cube is 6.
Let event B = The sum of the numbers rolled is 11.
What does P(BIA) represent?
Answer:
A. the probability that the sum is 11,given that the first number cube shows a 6
The correct answer is the probability that the sum is 11, given that the first cube shows the number 6.
What is conditional probability?Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome.
Let A and B be two events as given.
B|A = "Event B given Event A"
In other words, the probability Pr(B|A) says "event A has already happened, now what is the chance of event B"
P(B|A) is also called the "Conditional Probability" of B given A.
In our case, the probability Pr(B|A) represents "the probability that the sum is 11, given that the first cube shows the number 6".
Hence, the correct answer is the probability that the sum is 11, given that the first cube shows the number 6.

A lemonade seller calculates that it costs $ to produce glass of lemonade and $ to produce glass of lemonade. Assume the relationship between the cost and the number of glass of lemonade produced is linear. What is the most reasonable estimate for producing glass of lemonade
Question:
A lemonade seller calculates that it costs $50 to produce 52 glass of lemonade and $110 to produce 127 glass of lemonade. Assume the relationship between the cost and the number of glass of lemonade produced is linear. What is the most reasonable estimate for producing 193 glass of lemonade?
Answer:
[tex](a).\ y = 0.8x + 8.4[/tex]
[tex](b).\ Estimate = \$163[/tex]
Step-by-step explanation:
Represent number of lemonade with x and the cost with y.
So:
[tex](x_1,y_1) = (52,50)[/tex]
[tex](x_2,y_2) = (127,110)[/tex]
Solving (a): The linear relationship between them.
First, calculate slope (m)
m = ∆y ÷ ∆x
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{110 - 50}{127 - 52}[/tex]
[tex]m = \frac{60}{75}[/tex]
[tex]m = 0.8[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 50 = 0.8(x - 52)[/tex]
[tex]y - 50 = 0.8x - 41.6[/tex]
Make y the subject
[tex]y = 0.8x - 41.6 + 50[/tex]
[tex]y = 0.8x + 8.4[/tex]
Solving (b): Estimate of 193 lemonade
In (a), we have:
[tex]y = 0.8x + 8.4[/tex]
Substitute 193 for x
[tex]y = 0.8 * 193 + 8.4[/tex]
[tex]y = 154.4 + 8.4[/tex]
[tex]y = 162.8[/tex]
[tex]Estimate = \$163[/tex]

You’ll get 58.61 as the final sale price
If you do it the hard way, still the same answer
Answer: $58.61
Step-by-step explanation:

11. An experiment is set up to study the weights of 45 frogs after they are given a hormone treatment. The population mean is 22.70 grams with a standard deviation of 2.96 grams.
What is the standard error of the sample mean? Round your answer to the nearest hundredth.
The standard error of the sample mean is approximately (? ).
Answer: The standard error of the sample mean = 0.44
Step-by-step explanation:
Standard error of the sample mean = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex] , where [tex]\sigma[/tex] = population standard deviation , n= sample size.
Given : n= 45 , [tex]\sigma= 2.96[/tex] grams
The e standard error of the sample mean [tex]=\dfrac{2.96}{\sqrt{45}}[/tex]
[tex]=\dfrac{2.96}{6.7082039325}\\\\\approx\ 0.44[/tex]
Hence, the standard error of the sample mean = 0.44
