Should my answer be 85=360+12h
Answer:
h = [tex]\frac{- 275}{12}[/tex]
Step-by-step explanation:
85 = 360 + 12h
85 - 360 = 360 - 360 + 12h
- 275 = 12h
- 275 ÷ 12 = 12h ÷ 12
h = - 275/12

Answer:
56.1
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos N = PN / NO
cos 27 = 50/ x
x cos 27 / 50
x = 50/cos 27
x=56.11631188
Rounding to the nearest tenth
x = 56.1

Find the zeros of the function. Enter the solutions from least to greatest . h(x) = (- 4x - 3)(x - 3) lesser x = greater
9514 1404 393
Answer:
-3/4, 3
Step-by-step explanation:
The zeros are the values of x that make h(x)=0. Those are the values of x that make the factors of h(x) be zero.
-4x -3 = 0 ⇒ x = -3/4
x -3 = 0 ⇒ x = 3
The zeros of the function are -3/4 and 3.
Describe how the graph of y=2x and y=2x+7 are the same.
Answer:
These two equations produce a similar graph because they both share the same slope: 2. The only difference is that the y-intercept for the second equation is a positive 7, making the graph shift upwards. Other than this, both equations would be parallel (and identical) on the graph.

The function g is defined as follows.
g(x) = 2x²+7
If the graph of g is translated vertically downward by 5 units, it becomes the graph of a function h.
Find the expression for h(x).
x
Answer:
h(x) = 2x²+2
Step-by-step explanation:
Given the function g is defined as follows.
g(x) = 2x²+7
If the graph is translated by 5units vertically downwards, this means that the function will be reduced by 5 units to have;
h(x) = 2x²+7 - 5
h(x) = 2x²+2

When Abram was born, his parents put $2,000 into an account that yielded 3.5% interest, compounded semiannually. When he 16 , his parents will give him the money to buy a car. How much will Abram receive on his 16th birthday ?
Compound interest is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + \frac{r}{n} )^{nt}[/tex]
If P = $2000, R = 3.5%, n = 2 and T =16 years.
The amount received on his 16th birthday is $3480.
What is compound interest?
It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + \frac{r}{n} )^{nt}[/tex]
Where,
R = rate
P = principal.
n = number of times compounded annually.
t = number of years.
We have,
Principal = $2,000
Rate = 3.5%
Semiannually means twice a year so,
n = 2
Time = 16 years
Now,
The amount received on his 16th birthday:
A = P [tex](1 + \frac{r}{n} )^{nt}[/tex]
A = 2000 [tex](1 + \frac{3.5}{2\times 100}) ^{2\times16}[/tex]
A = 2000 [tex](1 +0.0175) ^{32}[/tex]
A = 2000 x [tex]1.0175^{32}[/tex]
A = 2000 x 1.74
A = $3480
Thus,
If P = $2000, R = 3.5%, n = 2 and T =16 years.
The amount received on his 16th birthday is $3480.

A research firm conducted a study to determine the average amount of money that smokers spend on cigarettes during a week. The firm found that the population mean amount that all smokers spend on cigarettes is $20 and the population standard deviation is $5. What is the probability that a new sample this year of 100 steady smokers spends between $19 and $21 on average
Answer:
0.9544 = 95.44% probability that a new sample this year of 100 steady smokers spends between $19 and $21 on average
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The firm found that the population mean amount that all smokers spend on cigarettes is $20 and the population standard deviation is $5.
This means that [tex]\mu = 20, \sigma = 5[/tex]
Sample of 100:
This means that [tex]n = 100, s = \frac{5}{\sqrt{100}} = 0.5[/tex]
What is the probability that a new sample this year of 100 steady smokers spends between $19 and $21 on average?
This is the pvalue of Z when X = 21 subtracted by the pvalue of Z when X = 19. So
X = 21
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{21 - 20}{0.5}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a pvalue of 0.9772
X = 19
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{19 - 20}{0.5}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a pvalue of 0.0228
0.9772 - 0.0228 = 0.9544
0.9544 = 95.44% probability that a new sample this year of 100 steady smokers spends between $19 and $21 on average

The scale on a map reads 0.5 inch = 30 miles. If two cities on the map are 5.75 inches apart, find the actual distance
between the cities.
Answer:
345 miles
Step-by-step explanation:
So we know that 2 cities are 5.75 inches apart on the map and the scale reads for every 0.5 inch its 30 miles. So we can first start of by diving 5.75 by 0.5, since we need to know how many “0.5” inches are in 5.75 inches. You’d get 11.5. Now 11.5 multiply that by 30 which would get you 345 miles.
Origin, one of the four characteristics of mapping rules, refers to _____. the use of a number that is not used again the use of a series of numbers in which each number is an equal distance from the next the use of ordered numbers such that two is less than three but greater than one the use of numbers used to group or sort responses when no order to the numbers exists the use of a series of numbers with a unique origin indicated by the number zero
Answer:
the use of a series of numbers with a unique origin indicated by the number zero.
Step-by-step explanation:
In Science, mapping experiment refers to an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Origin, one of the four characteristics of mapping rules, refers to the use of a series of numbers with a unique origin indicated by the number zero.
In Mathematics, the origin is generally chosen to start from zero on a graph that gives the relationship between two variables.
