Answer:

26.25 or 26 1/4

Step-by-step explanation:

Formula for rectangular prism:

\(V=lwh\)

Substitute in our known values:

V=3.5(5)(1.5)

solve

V=26.25

The volume is 26.25 (decimal form) or 26 1/4.

Hope this helps! :)

Answer: 26.25 in³

Step-by-step explanation:

Given volume formula for a rectangular prism:

     V = LWH

First, I am going to turn the \(\frac{1}{2}\)s into 0.5 to make it easier to multiply using a calculator. 3 and one-half becomes 3.5 and 1 and a half becomes 1.5.

Substitute known values and solve by multiplying.

     V = LWH

     V = (3.5 in)(5 in)(1.5 in)

     V = 26.25 in³

Answer:

2:3

Step-by-step explanation:

any choice that has a ration of 2:3

so 2:3, 4:6, 6:9, 10:15, 20:30, 24:36 etc...

Answer: g(f(10)) = g(√2x+5) = 6x-3

We need to substitute x = √2*10 + 5 into g(x) = 6x - 3

g(f(10)) = 6(√2*10 + 5) - 3 = 6√20 + 30 - 3 = 6√20 + 27

So g(f(10)) = 6√20 + 27.

Answer:

[-6 , 0]

Step-by-step explanation:

If the absolute value of an expression is equal to a number, that means that the expression itself could be equal to either the negative equivalent to that number or the positive equivalent.

for example, if my inequality is |x| > -3

x could either be:

-3 or 3

So,

| 2(x - 1) + 8 |  ≤  6

can be separated into two separate inequalities:

      2(x - 1) + 8  ≤   6

or,  2(x - 1) + 8  ≥ - 6

we solve these inequalities separately.

2(x - 1) + 8 ≤ 6

2x - 2 + 8  ≤ 6               [distribute 2]

2x  ≤ 0              [add 2 to both sides, subtract 8 from both sides]

x ≤  0   [finalize isolating x by dividing both sides of the equation by 2]

expressed as [in interval notation]:

(-∞, 0]

now, let's solve for the other inequality.

2(x - 1) + 8  ≥  - 6

2x - 2 +  8   ≥  - 6         [distribute 2]

2x  ≥  -12                   [add 2 to both sides, subtract 8 from both]

x  ≥  -6          [divide both by 2 to isolate x]

expressed as [in interval notation]:

[-6 , ∞)

So, our answer for x is going to be

-6 ≤ x ≤ 0

or, expressed in interval notation:

[-6 , 0]

We have that, when testing a certain type of truck tire on rough terrain, it is observed that 25% of the trucks fail to complete the test without blowout, the probability that of the next 15 trucks tested, at least one will not able to complete the test run without an explosion is 0.987

Given that when testing a certain type of truck tire on rough terrain, it is found that 25% of the trucks do not complete the test without blowout.So, the probability that a truck completes the test without a blowout is:

P (A complete truck test without blowout) = 1 - P (A complete truck test without an explosion) = 1 - 0.25 = 0.75

Now, we need to find the probability that of the next 15 trucks tested, at least one will not complete the test without an explosion. This can be found using the complement rule. The complement of the probability that at least one truck does not complete the test without a blowout is the probability that all 15 trucks complete the test without a blowout.

P(All 15 trucks complete the test without a blowout) = P(One truck completes the test without a blowout) x P(A second truck completes the test without a blowout) x ... x P(The fifteenth truck completes the test without a blowout) = 0.75 x 0.75 x ... x 0.75 (15 times)= 0.75^15= 0.013

But we need the probability that at least one truck fails to complete the test without a blowout, which is the complement of the above probability.

P(At least one truck does not complete the test without blowout) = 1 - P(All 15 trucks complete the test without blowout)= 1 - 0.013= 0.987

Therefore, the probability that of the next 15 trucks tested, at least one will not be able to complete the test run without an explosion is 0.987.

There isn't enough evidence to indicate that the percentage of Americans who own American-made cars is more than 53 percent.

A representative of a car manufacturer in the United States claimed that 53 percent of Americans owned American-made cars ten years ago.

However, today, the percentage is higher.

A research group conducted a study to find out whether the statement was true.

They found out that 56 percent of a random sample of car owners in the United States owned American-made cars. The appropriate hypothesis test produced a p-value of 0.283.

Assuming the conditions for inference were satisfied, is there sufficient evidence to conclude, at the level of significance of α = 0.05

At α = 0.05, we want to see if there is enough evidence to reject the null hypothesis.

Therefore, since α = 0.05, the null hypothesis (H0) should be tested against the alternative hypothesis (Ha).

H0: μ ≤ 0.53 (The percentage of Americans who own American-made cars is no higher than 53%).

Ha: μ > 0.53 (The percentage of Americans who own American-made cars is higher than 53%).

It is clear that the researcher's claim was not supported by the evidence since the p-value of 0.283 was far above the significance level of α = 0.05.

Therefore, there is no statistically significant evidence to reject the null hypothesis (H0).

The research group discovered that 56 percent of a randomly selected sample of car owners in the United States owned American-made cars.

The null hypothesis states that the percentage of Americans who own American-made cars is no higher than 53 percent.

Since the p-value was greater than 0.05, we failed to reject the null hypothesis.

These expressions hold true for any value of n and p, representing the probability of no errors and at least one error, respectively, in a binomial distribution with independent trials.

P(at least one error) = 1 - P(no errors).If the probability of a grader making a marking error on any particular question is 0.1, and there are ten questions marked independently,

we can calculate the probability of no errors and at least one error using the binomial distribution.

The probability of no errors is given by:

P(no errors) = (1 - probability of error)^number of trials

P(no errors) = (1 - 0.1)^10 = 0.9^10 ≈ 0.3487

The probability of at least one error is the complement of the probability of no errors:

P(at least one error) = 1 - P(no errors) = 1 - 0.3487 ≈ 0.6513

Now, if there are n questions and the probability of a marking error is p, the expressions for the probabilities are as follows:

P(no errors) = (1 - p)^n

P(at least one error) = 1 - P(no errors)

These expressions hold true for any value of n and p, representing the probability of no errors and at least one error, respectively, in a binomial distribution with independent trials.

Horizontal asymptotes: y = 2 ; vertical asymptotes: x = 2;  x- intercept and y- intercept is at (0,0).

A value that you approach steadily yet never quite reach is an asymptote. An asymptote is a line in mathematics that a graph reaches but never crosses. It can be horizontal, vertical, or slanted.

Given function:

f(x) = 2x² /(x² - 4)

horizontal asymptotes:

As the degree of both numerator and denominator is same that is 2.

The horizontal asymptotes y = a/b

a - leading coefficient of numerator

b - leading coefficient of denominator

y = 2/1 = 2

horizontal asymptotes: y = 2

vertical asymptotes:

Put the denominator = 0 and find the 'x'.

(x² - 4) = 0

x² = 4

x = ± 2

vertical asymptotes: x = 2

x- intercept : Put f(x) = 0 and find 'x'.

f(x) = 2x² /(x² - 4)

0 = 2x² /(x² - 4)

2x²  = 0

x = 0

x- intercept : x = 0

y- intercept : Put x = 0 and find 'f(x)'.

f(x) = 2(0)² /((0)² - 4)

f(x) = 0

y- intercept is at 0

Thus, x- intercept and y- intercept is at (0,0).

Answer:  59.73

====================================================

Explanation:

The markdown of 80% is the amount of money you save

80% of 298.67 = 0.80*298.67 = 238.936 = 238.94

You save $238.94

So the amount you pay, ie the sale price, is 298.67-238.94 = 59.73 dollars.

-----------------------------------------

Another approach:

If you save 80%, then you still pay the remaining 20%

20% of 298.67 = 0.20*298.67 = 59.734 = 59.73

Therefore ,the answer to the above trigonometry issue is therefore that the river is 70 feet wide.

The study of the connections between the angles and sides of triangles is known as trigonometry. Due to the fact that each straight-sided figure may be reduced to a collection of triangles, trigonometry is commonly utilized in geometry. There are a mind-boggling number of connections between trigonometry and other branches of mathematics, especially algebra, real or complex, integrals, logarithms, and infinite series.

Here,

Figure depicts a right triangle which, in relation to angle, its next side has length d or its wrong side is equal to the river's width, y. As a result,

tanθ= d/ y

=> y=dtanθ

=> y = (100m)tan(35.00)=70ft

The river measures 70 feet in width.

As a result, the trigonometry problem's answer indicates that the river's width is 70 feet.

Answer:

To find -134 + 53, add the ones place (4+3=7) and the tens place (5+3=8), giving you -81.

Answer: -81.

Answer:

-81

Step-by-step explanation:

You subtract the absolute values and take the sign of the larger absolute value.

Absolute value is the distance from zero.  This will be a positive number

134 - 53 = 81

The sign will be negative because the sign of the higher absolute value number is negative.  134 has a larger absolute value than 53 and it is negative, so our answer is negative.

The height of the lean-to on its vertical side is 8 feet.

To find the height of the lean-to on its vertical side, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the vertical side is the hypotenuse, and the length and width are the other two sides.

So, we have:

\(height^2 = hypotenuse^2 - width^2\)

We know the length of the roof (the hypotenuse) is 17 feet, and the width is 15 feet. So we can plug these values into the equation and solve for the height:

\(height^2 = 17^2 - 15^2\\height^2 = 289 - 225\\height^2 = 64\\height = 8\)

Therefore, the height of the lean-to on its vertical side is 8 feet.
