TRUE or FALSE: Billy is paid $32 for 8 hours of work. He gets peid $4 per hour

Pavlova-9 [17]

Answer:

True

Step-by-step explanation:

We know Billy is paid $32 for 8 hours of work.

All we have to do is divide 32 by 8 to see if whether he gets paid 4 dollars an hour,

32/8

==> 4

This is true

Consider the polynomial 2x5 + 4x3 - 3x8

almond37 [142]

Answer:

Step-by-step explanation:

Considering the polynomial 2x⁵ + 4x³ - 3x⁸. The polynomial is not yet in standard form. For a polynomial to be in standard form, the power of the variables must decrease as we progress to the right of the expression.

A) The polynomial in standard form is therefore - 3x⁸ + 2x⁵ + 4x³. We can see that the power are reducing as we move through each terms i.e from 8 to 5 then to 3.

B) The degree of a polynomial is the maximum degree among all the terms of the polynomial. The term that has the maximum degree is -3x⁸. Hence, the degree of the polynomial is 8

C) There are only 3 terms in the polynomial given. The terms are separated by mathematical signs. The terms if the polynomial are 2x⁵, 4x³ and - 3x⁸.

D) The leading term of the polynomial is the term that comes first after rewriting the polynomial in standard format. Given the standard from of the polynomial given as -3x⁸ + 2x⁵ + 4x³, the leading term will be - 3x⁸

E) Given the leading term to be - 3x⁸, the leading coefficient of the polynomial will be the coefficient of the leading term. The coefficient of -3x⁸ is -3

T-shirts are $10 each and jogging pants are $15 each. If you buy 4 t-shirts and 2 pairs of jogging pants,

11Alexandr11 [23.1K]

Since there's a discount given, the total amount that will be paid will be $49.

Based on the information given, the total cost for the things bought will be:

= ($10 × 4) + ($15 × 2)

= $40 + $30 = $70

The total amount that will be paid will be:

= $70 - (30% × $70)

= $70 - $21 = $49

In conclusion, $49 will be paid.

Data on the modulus of elasticity obtained 1 minute after loading in a certain configuration and 4 weeks after loading for the s

mixer [17]

Answer:

The Confidence Interval = (2180, 2782)

Lower Bound for the true average difference between 1-minute modulus and 4-week modulus = 2180

Upper Bound for the true average difference between 1-minute modulus and 4-week modulus = 2782

- The interval obtained represents the range of values that the true average difference between 1-minute modulus and 4-week modulus can take on.

Step-by-step explanation:

The confidence interval for any distribution is the range of values that the true population mean can take on with some level of confidence.

It is given mathematically as

Confidence Interval = (Sample Mean) ± (Margin of Error)

The Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as

Margin of Error = (Critical Value) × (Standard Error of the Mean)

Before anything, we first state the conditions necessary for the confidence interval calculated to be valid.

- The sample must be a random sample extracted from the population distribution using random sampling technique.

- The sample distribution must be normal or approximately normal and this is confirmed by knowing that the population distribution is normal or almost normal.

These two conditions are assumed to be plausible for this sample distribution.

Here, we need the confidence interval for the true average difference between 1-minute modulus and 4-week modulus.

So, before anything, we need to first fin the sample mean and standard deviation for the differences obtained from the sample specimens.

904, 3370, 2580, 3117, 2850, 2690, 2180, 1241, 2210, 2350, 2260, 2758, 2880, 2750, 3520, 2033

Mean = (Σx/N)

Σx = Sum of all the variables = 39693

N = Sample size = 16

Sample Mean = (39693/16) = 2480.8125

Standard deviation = $\sqrt{\frac{Σ(x - xbar)^{2}}{N-1}\\}$

x = each variable

xbar = sample mean = 2480.8125

Note that we use (N-1) for the standard deviation because it is a sample standard deviation.

$\sqrt{\frac{Σ(x - xbar)^{2}}{N-1}\\}$ = √(7227548.4375/15) = √(481836.5625)

= 694.14448243863 = 694.1445

Confidence Interval = (Sample Mean) ± (Margin of Error)

Margin of Error = (Critical Value) × (Standard Error of the Mean)

Confidence Interval = (Sample Mean) ± [(Critical Value) × (Standard Error of the Mean)]

Critical Value is obtained from the t-distribution table since no information on the population standard deviation is known.

For that, we need the significance level for the test and the degree of freedom.

Significance level = α = 0.05 (given in the question)

Degree of freedom = N - 1 = 16 - 1 = 15

t(0.05, 15) = 1.753 (from the t-distribution tables)

Standard error of the Mean = σₓ = (σ/ $\sqrt{N}$ ) = (694.1445/ $\sqrt{16}$ ) = 173.536125 = 173.536

Confidence Interval = (Sample Mean) ± [(Critical Value) × (Standard Error of the Mean)]

CI = (2480.8125) ± [(1.753 × 173.536)]

CI = (2480.8125) ± (301.09385)

CI = (2179.71865, 2781.90635)

CI = (2180, 2782)

This interval represents the range of values that the true average difference between 1-minute modulus and 4-week modulus can take on.

Hope this Helps!!!
