On a resent business trip it took 7 hours 30 minutes to drive 375 miles how many miles per hour was the average

Answers

divide 375 by 7.5 to get the answer

Answer:

50 miles / hours.

Step-by-step explanation:

Speed may be defined as the distance covered by the object per unit time.

Speed = [tex]\frac{distance}{time}[/tex]

the distance of the business trip = 375 miles.

the time taken by the business trip = 7 hours 30 minutes = 7.5 hrs.

Speed = [tex]\frac{375}{7.5}[/tex]

Speed = 50 miles / hours.

Here, the average of miler per hour is 50 miles / hours.

The volume of a rectangular prism is b3 + 8b2 + 19b + 12 cubic units, and its height is b + 3 units. The area of the base of the rectangular prism is square units.

Answers

Given:

The volume of the rectangular prism is 

[tex] b^{3}+8 b^{2} +19b+12 [/tex],

the height is h=(b+3)

1. The volume of a rectangular prism is (base area)*height

also, notice that the volume is a third degree polynomial, the height is a 1st degree polynomial, so the base area must be a 2nd degree polynomial, whose coefficients we don't know yet.
Let this quadratic polynomial be [tex](mb^{2}+nb+k)[/tex]

 
2

[tex]b^{3}+8 b^{2} +19b+12=(mb^{2}+nb+k)*(b+3)[/tex]


notice that  [tex]b^{3}[/tex] is the product of the largest 2 terms: [tex]mb^{2}[/tex] and b, so m must be 1

also, notice that 12 is the product of the constants, k and 3

so k*3=12, this means k=4

3
we write the above equality again:

[tex] b^{3}+8 b^{2} +19b+12=(b^{2}+nb+4)*(b+3)[/tex]


[tex](b^{2}+nb+4)(b+3)= b^{3}+3 b^{2} +nb^{2}+3nb+4b+12[/tex]

=[tex]= b^{3}+(n+3)b^{2}+(3n+4)b+12[/tex]


4
now compare the coefficient with the left side:

[tex]8 b^{2}=(n+3)b^{2}[/tex]

8=n+3

n=5


substituting n=5: 

the base area is [tex]b^{2}+5b+4 [/tex]

Answer: [tex]b^{2}+5b+4 [/tex]


Answer:

b^2 + 5b +4

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A commercial jet airplane climbs at takeoff with slope m = 4/9.

Then the equation of the line will be given as,

y = (4/9)x

The y-intercept is zero.

The horizontal direction will the airplane fly to reach an altitude of 20,000 ft above the takeoff point will be

20,000 = (4/9)x

180,000 = 4x

x = 180,000 / 4

x = 45,000 feet

An investigator wants to estimate caffeine consumption in high school students. how many students would be required to estimate the proportion of students who consume coffee? suppose we want the estimate to be within 5% of the true proportion with 95% confidence.

Answers

We can solve this problem by referring to the standard probability distribution tables for z.

We are required to find for the number of samples given the proportion (P = 5% = 0.05) and confidence level of 95%. This would give a value of z equivalent to:

z = 1.96

Since the problem states that it should be within the true proportion then p = 0.5

Now we can find for the sample size using the formula:

n = (z^2) p q /E^2

where,

 p = 0.5

q = 1 – p = 0.5

E = estimate of 5% = 0.05

Substituting:

n = (1.96^2) 0.5 * 0.5 / 0.05^2

n = 384.16

Around 385students are required.

The third term of an arithmetic sequence is 21, and the eighth term is 56. The first term is _____.

Answers

The first term is 7. This is because the sequence has a pattern of increasing by 7. If the first term was 7, the second would be 14, the third would be 21. The 4th would be 28, continue to the 8th term 56.
Final answer:

The first term of the given arithmetic sequence is 7. This can be determined by finding the common difference and moving backwards from the third term using this value.

Explanation:

The subject of this question is Arithmetic Sequence which is a topic in mathematics. An arithmetic sequence is defined by a common difference (d) between consecutive terms.

To solve this problem, we have to find the common difference first. The difference between the 8th term (56) and the 3rd term (21) is 35. But since there are 5 steps from the 3rd term to the 8th term, each step (or the common difference) must be 35 ÷ 5 = 7.

Now that we have the common difference (7), we can reverse it from the 3rd term (21) back to the 1st term which gives us: 21 - 2(7) = 7. So, the first term is 7.

Answers

We are given the following variables:

Normal distribution

u = sample mean = 74

s = standard deviation of the samples = 7

x = sample value = 81

Since we are asked to find percent of the scores less than 81, this means we have to find the proportion using the z-score. The formula for z score is:

z = (x – u) / s

Substituting the given values:

z = (81 – 74) / 7

z = 1

Using the standard normal distribution tables for z, we find that:

P = 0.8413            at z = 1

Therefore this means that 84.13% of scores are less than 81.
