Oliver had m dollars to spend on a backpack for the new school year. The expression below represents the amount of money he had remaining after purchasing the backpack.
m - (y + 0.07y)
If his total purchase included the backpack and tax, which statement best describes y?
A.
The amount of money he had to spend on the backpack.
B.
The amount of tax for the backpack.
C.
The price of the backpack, including tax.
D.
The price of the backpack, not including tax.
Answer:
Option A
Step-by-step explanation:
Y is the amount of back pack
The total amount is represented by m
If Y is the cost of back pack purchased by Oliver, then 0.7 Y is the tax applicable on the purchase of back pack
Hence, the remaining cost would be total amount with Oliver minus the cost of back pack and the tax applicable on the purchase of back pack
Remaining cost = m - (y + 0.07y)
Hence, option A is correct
sixth graders have the choice between two end of year trips: going to the zoo or going to an amusement park. There are 264 scholars in the sixth grade. The number of scholars who chose to go to the amusement park is 140% of the number of scholars who chose to go to the zoo. How many scholars chose to go to the amusement park
Answer:
Step-by-step explanation:
154 scholars chose to go to the amusement park.
What is an equation?An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of scholars who chose to go to the amusement park and y represent the number of scholars who chose to go to the zoo.
scholars who chose to go to the amusement park is 140% of the number of scholars who chose to go to the zoo. Hence:
x = 140% of y = 1.4y
Also, There are 264 scholars in the sixth grade, hence:
x + y = 264
1.4y + y = 264
y = 110
x = 1.4(110) = 154
154 scholars chose to go to the amusement park.

Two traffic lights operate independently. Your probability of being stopped at the first one is 0.4 and your probability of being stopped at the second one is 0.7. The probability at being stopped at the first light and second light is 0.3. What is your probability of being stopped at the first light or second light?Make sure to show your work. NEED HELP ASAP
Answer:
Most people found the probability of just stopping at the first light and the probability of just stopping at the second light and added them together. I'm just going to show another valid way to solve this problem. You can solve these kinds of problems whichever way you prefer.
There are three possibilities we need to consider:
Being stopped at both lights
Being stopped at neither light
Being stopped at exactly one light
The sum of the probabilities of all of the events has to be 1 because there is a 100% chance that one of these possibilities has to occur, so the probability of being stopped at exactly one light is 1 minus the probability of being stopped at both lights minus the probability of being stopped at neither.
Because the lights are independent, the probability of being stopped at both lights is just the probability of being stopped at the first light times the probability of being stopped at the second light. (0.4)(0.7) = 0.28
The probability of being stopped at neither is the probability of not being stopped at the first light, which is 1-0.4 or 0.6, times the probability of not being stopped at the second light, which is 1-0.7 or 0.3. (0.6)(0.3) = 0.18

Exercise 8.12 introduces data on the average monthly temperature during the month babies rst try to crawl (about 6 months after birth) and the average rst crawling age for babies born in a given month. A scatterplot of these two variables reveals a potential outlying month when the average temperature is about 53F and average crawling age is about 28.5 weeks. Does this point have high leverage
Answer:
The point has a high leverage
Step-by-step explanation:
The point has a high leverage as it would act as an infinitesimal point that will have a very huge/drastic impact on the fit of the model, and this impact can be seen in such ways as listed below :
Smaller coefficient of determinationHigher sum of squares errorremoving this point will eliminate these drastic impact and make the correlation to be better.
From the information given about the outliner, the given point is not influential and therefore does not have high leverage.
What is an outliner?An outlier refers to a data point whose response does not follow the general trend of the rest of the data.
A data point has high leverage if it has an extreme predictor x value. Here, x = 53 and, y = 28.5.
X is not an extreme point, the data point is not high leverage but an outlier. The data point doesn't follow the general trend of the rest of the data.
Hence the given point is not influential.

Answer:
C) 4
Step-by-step explanation:
We observe that the top segments are in the same 3:4 ratio as the bottom segments. This means they are the same lengths: 3x = 12, 4x = 16. Either of these equations tells us x = 4.

Additional comment
In case you aren't convinced, you can solve this using the secant rule for segments and circles: the product of the lengths to the circle intercepts are the same for both secants.

Answer:
An =4^(n-1)
Step-by-step explanation:
hello :
the sequence is geometric because : (-64)/(-16) = (-16)/(-4)=-4/-1= 4=r
the nth term is : An =A1 × r^(n-1)
a common ratio is : r and A1 the first term
in this exercice : r =4 A1 = 1
An =A1 × r^(n-1)

The pH of a liquid is a measure of how acidic or basic it is. The concentration of hydrogen ions in a liquid is labeled (H+). Use the formula pH = -log[H] to find the pH level, to the nearest tenth, of a liquid with [H] about 8.1 x 10-7,
a = 6.1
b = 7.9
с = -7.9
d = 7.0
Answer:
pH = 6.1
Step-by-step explanation:
pH = -log[H]
pH = -log[8.1 x 10^-7]
pH ≈ 6.09
Therefore, option a, 6.1, is closest to this value and is the correct answer.

Answer:
12 ft
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle θ = 41.5°
Opposite = 8 ft
Length of handrail =?
We can obtain the length of the handrail by calculating the Hypothenus. This can be obtained as follow:
Angle θ = 41.5°
Opposite = 8 ft
Hypothenus =?
Sine θ = Opposite /Hypothenus
Sine 41.5 = 8 / Hypothenus
0.6626 = 8 / Hypothenus
Cross multiply
0.6626 × Hypothenus = 8
Divide both side by 0.6626
Hypothenus = 8 / 0.6626
Hypothenus = 12 ft
Thus, the Lenght of the handrail is 12 ft
