Jack runs 3 miles 4 times a week. How many miles does Jack run in 6 weeks
The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which is 40% of the total miles of their trip. How many total miles is the Jackson’s trip from Boston to New York?
The answer you are looking for is 210 miles.
To find this answer you must first make 40% into a decimal. To do so, simply divide 40 by 100. This will give you 0.4.
Next, you divide 84 by 0.4. You divide because the percentage of a number is found by multiplying said number by the decimal form of the percent. Since we arent looking for the percentage of a number, but rather the number from which the percentage came, we do the opposite operation.
84 ÷ 0.4 = 210. Thus meaning 210 miles is your answer.
I hope this helps!
The total number of miles that Jackson’s trip from Boston to New York will be 210 miles.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which are 40% of the total miles of their trip.
Let x be the total number of miles. Then the equation is given as,
0.40x = 84
Simplify the equation, then we have
x = 84 / 0.40
x = 210 miles
The total number of miles that Jackson’s trip from Boston to New York will be 210 miles.

CNNBC recently reported that the mean annual cost of auto insurance is 965 dollars. Assume the standard deviation is 113 dollars. You will use a simple random sample of 57 auto insurance policies.Find the probability that a single randomly selected policy has a mean value between 939.6 and 972.5 dollars.P(939.6 < X < 972.5)
Answer:
P(939.6 < X < 972.5) = 0.6469
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.
CNNBC recently reported that the mean annual cost of auto insurance is 965 dollars. Assume the standard deviation is 113 dollars.
This means that [tex]\mu = 965, \sigma = 113[/tex]
Sample of 57:
This means that [tex]n = 57, s = \frac{113}{\sqrt{57}} = 14.97[/tex]
Find the probability that a single randomly selected policy has a mean value between 939.6 and 972.5 dollars.
This is the pvalue of Z when X = 972.5 subtracted by the pvalue of Z when X = 939.6. So
X = 972.5
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{972.5 - 965}{14.97}[/tex]
[tex]Z = 0.5[/tex]
[tex]Z = 0.5[/tex] has a pvalue of 0.6915
X = 939.6
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{939.6 - 965}{14.97}[/tex]
[tex]Z = -1.7[/tex]
[tex]Z = -1.7[/tex] has a pvalue of 0.0446
0.6915 - 0.0446 = 0.6469
So
P(939.6 < X < 972.5) = 0.6469
Find the value of given trigonometric function cot (-330°)
Answer:
The exact value should be
[tex] \sqrt{3} [/tex]
Step-by-step explanation:
Though you can get this directly out from your calculator, but you can utilize the opposite angle identities, cot(-
θ)=-cot θ, then use the trig identity, which is
[tex] \cot(θ) = \frac{ \cos(θ) }{ \sin(θ) } [/tex]
So cot (-330)=cos (-330)/sin (-330)

5.87998 + 3.100 = [?]
The answer after performing mathematical operation is 8.97998 .
What is mathematical operations?
In order to add, subtract, multiply, or divide two or more quantities, one must perform a series of four fundamental operations known as mathematical operations. They involve the study of numbers and the order of operations, which are important in all other areas of mathematics like algebra, data processing, and geometry. Without employing mathematical operation rules, we are unable to solve the issue. The addition, subtraction, multiplication, and division operations all follow the same four fundamental rules.
Here the given ,
=> 5.87998 + 3.100
=> 5.87998
+ 3.10000
--------------------
8.97998
=> 5.87998+3.100=[8.97998]
Hence after performing mathematical operations the answer is 8.97998.

Choose any two points that are on the line, find the difference between the y and the difference between the x, and set as a fraction.
In this case, we can use (0,0) and (1,1) since both points are on the line.
Difference in y: 1 - 0 = 1
Difference in x: 1 - 0 = 1
Write as a fraction: 1/1

How do I solve this question?
Answer:
The correct answer is given by option a.
Step-by-step explanation:
Rational roots theorem:
In the rational roots theorem, we take the leading coefficient(which multiplies the term of x with the highest exponent) and the independent term(which does not multiply any value of x).
The possible roots have the format p/q, in which p are the factors of the independent term, and q are the factors of the leading coefficient.
In this question:
Leading coefficient: 3
Independent term: 15
Factors of the independent term: {1, 3, 5, 15} -> p
Factors of the leading coefficient: {1,3} -> q
Possible roots:
All possible values, positive or negative, in which p is divided by q. So
[tex]\pm \frac{1}{1}, \pm \frac{1}{3}, \pm \frac{3}{1}, \pm \frac{3}{3}, \pm \frac{5}{1}, \pm \frac{5}{3}, \pm \frac{15}{1}, \pm \frac{15}{3}[/tex]
So, without the repeated terms, they are:
[tex]\pm \frac{1}{3}, \pm \frac{5}{3}, \pm 1, \pm 3, \pm 5, \pm 15[/tex]
