Answer: 50 1/4

Step-by-step explanation:

The estimate of the product is reasonable

The product expression is given as

759 x 68

As an estimate, we have

759 - 760

68 = 70

So, we have:

759 x 68 = 760 * 70

Evaluate the product

759 x 68 = 53200

For the actual product, we have

759 x 68 = 51612

The estimate and the actual product both approximate to 50000

Hence, the estimate of the product is reasonable

The margin of error is 3.083 min

Margin of Error: The margin of error is the range of error permitted around the sample statistic in order to estimate the population parameter. The margin of error indicates the size of the confidence interval. The breadth of the confidence interval increases with the margin of error.

Sample size, n=24

Sample mean, ¯x=31.5 min

Sample standard deviation, s=7.3 min

Confidence level, c=95%

=0.95

From the given information we can calculate the below-required quantities,

Significance level, α=1−c=1−0.95=0.05

Degrees of freedom, DOF=n−1

=24−1

=23

Now from the t-distribution table,

The value of t (α2, DOF) is,

t (0.025,23) = 2.069  

Hence the margin of error will be,

MOE= t (α2, DOF) × s/√ n

=2.069×7.3/√24

=3.083 min

i. The upper limit of the confidence interval will be,

UL=¯x + MOE=31.5+3.083=34.583

The lower limit of the confidence interval will be,

LL=¯x−MOE

=31.5−3.083

=28.417

Hence, the 95% confidence interval is (28.417,34.583)

(28.417,34.583)

The answer is 28.417,34.583

ii. The required answer is MOE=3.083 min

ii. We have found the 95% confidence interval for the population mean to be (28.417,34.583). This means with 95 % confidence; it can be said that the population mean commute time is between the bounds of the confidence interval.

In a quadrilateral with a perimeter of 120 inches, the longest of the four sides has length equal to 33 inches.

A quadrilateral is a two-dimensional figure that has 4 sides and 4 vertices. The perimeter of any two-dimensional figure is the sum of all its sides.

If the lengths of the four sides of a quadrilateral (in inches) are consecutive odd integers, we can express each side as:

x = length of side 1(odd integer)

x + 2 = length of side 2

x + 4 = length of side 3

x + 6 = length of side 4

If the perimeter of the quadrilateral is 120 inches, then the sum of the four sides is equal to 120 inches.

x + (x + 2) + (x + 4) + (x + 6) = 120

Simplifying and solving for x.

4x + 12 = 120

4x = 108

x = 27

Substitute the value of x on the expression for the length of the 4th side(longest side).

longest side = x + 6 = 27 + 6

longest side = 33 inches

The values of x that will make x² = 9 are positive 3 and negative 3.

A quadratic equation is an algebraic equation that has highest degree of 2, therefore, it also has two roots or we can say it has two solutions.

We know sign distributions that negative distributed to a negative is positive and positive distributed to a positive also results in positive.

∴ 9 can be obtained by either multiplying (-3)(-3) or (3)(3).

So, the value of x that will make x² = 9 is

x = ± √9

x = ± 3.

Each term of the sequence is 2 more than the previous term.

The third term is 8.

The sequence is an arithmetic sequence base on the difference.

Using arithmetic sequence formula,

aₙ = a + (n - 1)d

where

Therefore, let's used the third term to find the first term.

8 = a + 2d

8 = a + 2(2)

8 = a + 4

a = 8 - 4

The given  logarithmic expression statement is false. Because log₄7- log ₄3 = log₄(7/3).

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

Answer:

The length of UV is 10 units.

Step-by-step explanation:

It is given that the points T, U, V and W all lie on the same line segment, in that order, such that the ratio of TU:UV:VW is equal to 1:5:2.

Now, we need to calculate UW if TW = 32.

So, TU : UV : VW = 2 : 5 : 5

=> TW = 24

From the above conditions it can be observed that;

=> Ratio of TU = 2

=> Ratio of UV = 5

=> Ratio of VW = 5

Firstly, we have to sum up the total ratio that is;

=> Total = Ratio of TU + Ratio of UV + Ratio of VW

=> Total = 2 + 5 + 5

=> Total = 12

Now, we need to calculate the length of UV from which we get;

=> UV = 5/12 * 24

=> UV = 10

Therefore; length of UV is 10 units.

The evaluated value of [tex]log_{7}30[/tex] is 1.748

Change of base formula is used to change the base of the logarithm. It is used to write a logarithm of a number with a given base as the ratio of two logarithms each with the same base that is different from the base of the original logarithm.

According to the change of base formula:

       [tex]log_{a}b = \frac{log_{x}b }{log_{x} a}[/tex]

where base x is considered base 10

According to the question, we have to find the value of [tex]log_{7} 30[/tex]

Thus applying change of base formula we get

    [tex]log_{7} 30 = \frac{log_{10} 30}{log_{10} 7}[/tex]

calculating the value of log from the calculator we get,

        [tex]log_{7} 30 = \frac{1.477}{0.845}[/tex]

        [tex]log_{7} 30 = 1.748[/tex]
