Answer: 2.5, 5.3

Step-by-step explanation:

\(-16t^2 +126t=217\\ \\ 16t^2 -126t+217=0\\\\t=\frac{-(-126) \pm \sqrt{(-126)^2 -4(16)(217)}}{2(16)}\\\\t \approx 2.5, 5.3\)

Answer:

33 minutes

Step-by-step explanation:

To find the mean, you first must add up the values given.

45 + 25 + 35 + 20 + 40 = 165

Now, divide the sum by the number of values you have.

165/5 = 33

The mean number of minutes she spent practicing is 33.

Answer:

y = (1/2)x + 16

Step-by-step explanation:

General point/slope form is

y = mx +b (the two points given are (4,18) and (16,24))

slope = rise/run = (24-18)/(16-4) = 6/12 = 1/2

y = (1/2)x + b

pick one point (4,18) and plug in

18 = (1/2)4 + b

18 = 2 + b

b = 16 (he still gets $16 for zero chores)

So

y = (1/2)x + 16

                     \(=\frac{1}{2}-3(\frac{1}{2}+\frac{2}{2} )^{2}\\\\\\=\frac{1}{2}-3(\frac{3}{2})^{2}\\\\\\=\frac{1}{2}-3*\frac{9}{4}\\\\\\=\frac{1*2}{2*2}-\frac{27}{4}\\\\\\=\frac{2}{4}-\frac{27}{4}\\\\\\=\frac{2-27}{4}\\\\=\frac{-25}{4}\\\\\\= -6\frac{1}{4}\)

Answer:

She forgot to include pi as a factor in the volume expression.

Step-by-step explanation:

The exact question is as follows :

Given - Mia is calculating the volume of the cylinder below using the following work.

A cylinder with height of 47 meters and diameter of 35 meters.

To find - What was Mia’s first error?

Solution -

Given that,

Diameter of cylinder = 35 centimeter

Height of cylinder = 47 centimeter

Now,

We know that,

Volume of cylinder, V = \(\pi\)r²h

Also,

We know, Diameter = 2×Radius

⇒Radius = Diameter ÷ 2

              = 35 ÷ 2

              = 17.5

⇒Radius = 17.5

SO,

The volume becomes, V = \(\pi\)(17.5)²(47)

                                         = \(\pi\)(306.25)(47)

                                         = 14393.75 \(\pi\)

So,

The volume of the cylinder becomes 14393.75 \(\pi\) m³

But

Mia calculated the Volume is 14393.75

By comparing with the actual Volume, we get

The Mia's first error is - She forgot to include pi as a factor in the volume expression.

Answer:

$130.68

Step-by-step explanation:

1 acre = 43,560 square feet

3/4 of 43560 = 32,670 (So that would be 76,230 sq ft in 1.75 acres because 43560 + 32670 = 76230)

We need to divide the total by 35 plots.

76230 / 35 = 2178, using long division.

2,178 square feet is just one plot of 35. We need to multiply 2178 by 0.06.

The ANOVA procedure is a statistical approach used to determine whether the means of three or more groups are equal.

ANOVA, which stands for Analysis of Variance, is a statistical technique that compares the means of multiple groups to assess if they are significantly different from each other. It is specifically designed for situations where there are three or more groups or treatments being compared. The goal is to determine whether the observed differences in means are statistically significant or if they can be attributed to random variation. ANOVA assesses the variability between the group means and within each group, allowing researchers to make inferences about population means based on sample data. Therefore, the correct answer is that the ANOVA procedure is used to determine whether the means of three or more groups are equal.

61 (nearest whole numbers) is the sample of bacteria will be after 18 hours.

One-celled organisms are called bacteria. Bacteria come in a wide variety of varieties. Almost everywhere in your body and on your skin, they are present. Some microorganisms are beneficial or even benign. Others may spread illnesses and infections.

Finding hazardous bacteria in or on your body that could be making you unwell is possible with the aid of a bacteria culture test. You must provide a sample of your blood, urine, skin, or another type of tissue in order to undergo the test. Depending on where the infection appears to reside, a different sample type is required.

Let, F(t)= ce^kt - equation 1

Where F(t) is the number of bacteria at time t hours and c, k are the constants to be determined .

given that there are initially 11 bacteria

i.e; F(0)=11

C*E^0=11

now , C=11

Also the bacteria population grows at hardly Rate of 10%

i.e F(1)=11+(10/100)*100

11*e^k*1=121/10

e^k=121/10

= 11/10

now K=ln(11/10)

hence the size of population after t hours is :

F(t)=11e^t*ln(11/10)

At t=18 , F(18) =11e^18ln(11/10)

therefore , F(18) = 61.159

round off ≈ 61

Two conditions are not met, the AST cannot be used to determine the convergence or divergence of the series.

The Alternating Series Test (AST) is a tool that can be used to determine whether a series converges or not.

In order to apply the AST, the series must meet two conditions:
The terms of the series must alternate in sign. In other words, the terms should switch between positive and negative values.

Mathematically, this can be represented as \((-1)^n \times a_n or ( -1 ) ^(n+1) \times a_n\) for some sequence a_n.
The terms of the series must be decreasing in magnitude, and the limit of the sequence a_n must be 0 as n approaches infinity.

In mathematical notation, this can be written as: \(a_(n+1) \leq  a_n\)for all n, and \(\lim_{n \to \infty} a_n   = 0\).
If a series meets both of these conditions, then the AST can be applied, and the series converges.

Either of these conditions is not met, the AST cannot be used to determine the convergence or divergence of the series.
To recap, the Alternating Series Test can be used to determine if a series converges if and only if:
The series alternates in sign (terms switch between positive and negative values).
The terms of the series are decreasing in magnitude, and the limit of the sequence \(a_n\) is 0 as n approaches infinity.

Irene will require approximately 2.2 repetitions to achieve the "standard" if the standard is 28 minutes per repetition.

To calculate the number of repetitions Irene will require to achieve the standard, we can use the concept of proportional reasoning. We can set up a proportion using the time taken for the initial repetition and the time taken for the next repetition.

Let's define "x" as the number of repetitions Irene will need to achieve the standard. We can set up the proportion as follows:

43 minutes / 1 repetition = 38 minutes / x repetitions

Cross-multiplying and solving for "x" gives us:

43x = 38

x = 38 / 43

x ≈ 0.8837

Since we're looking for a whole number, we need to round up. Therefore, Irene will require approximately 2.2 repetitions to achieve the "standard." Rounding up to the next whole number, she will need 3 repetitions.

Please note that this calculation assumes the time taken for each repetition is consistent and that Irene's performance improves over time. It's also worth considering that additional factors may affect Irene's progress, such as training, experience, and any potential improvements in efficiency.

The solutions of the simultaneous equations are;'

1) r = -2, s = -3, t = -5

2) r = 0.6, s = 2.3, t = 3.9

A simultaneous equation consist of two or more variable unknows  imn two or more equations respectively, in which the value of the variables are the same in each equation.

1) -2·r - 6·s + 5·t = -3...(1)

4·r - 2·s - 4·t = 18...(2)

r + 4·s + t = -19...(3)

Multiplying equation (3) by 2 and adding the result to equation (1), we get;

2 × (r + 4·s + t) = 2 × -19 = -38

-2·r - 6·s + 5·t + (2·r + 8·s + 2·t) = -38

2·r - 2·r + 8·s - 6·s + 5·t + 2·t = 2·s + 7·t = -38 - 3 = -41

2·s + 7·t = -41...(4)

Multiplying equation (1) by 2 and adding the result to equation (2), we get;

2 × ( -2·r - 6·s + 5·t ) = -4·r - 12·s + 10·t

4·r - 2·s - 4·t + ( -4·r - 12·s + 10·t) = -14·s + 6·t = -6 × 18 = 12

-14·s + 6·t = 4 × 18 = 72

-14·s + 6·t = 12...(5)

Multiplying equation (4)m by 7, we get;

7 × (2·s + 7·t) + -14·s + 6·t =  55·t = 7×(-41) + 12 =  -275

t = -275 ÷ 55 = -5

t = -5

2·s + 7·t = -41

2·s + 7×(-5) = -41

2·s = -41  -  7×(-5)  = -6

s = -6 ÷ 2 = -3

s = -3

r + 4·s + t = -19

r + 4×(-3) + (-5) = -19

r - 17 = -19

r = -19 + 17 = -2

r = -2

2)  r - s + 3·t = 10...(1)

-6·r + 4·s - 4·t = -10...(2)

6·r + 2·s + 2·t = 16...(3)

Adding equation (2) to equation (3), we get;

6·r + 2·s + 2·t + (-6·r + 4·s - 4·t ) =  6·s - 2·t = 6

6·s - 2·t = 6...(4)

Multiplying equation (1) by 6 and adding the result to equation (2), we get;

6 × ( r - s + 3·t ) = 6·r  - 6·s + 18·t = 6 × 10 = 60

6·r  - 6·s + 18·t  + (-6·r + 4·s - 4·t) = 6 × 10 - 10 = 60 + (-10) = 50

-2·s + 14·t = 50...(5)

Multiplying equation (5) by 3 and add the result to equation (4), we get;

6·s - 2·t + 3 × (-2·s + 14·t ) = 40·t = 6 + 3 × 50 = 156

t = 156/40 =  3.9

t = 3.9

6·s - 2·t = 6

6·s - 2·×3.9 = 6

6·s = 6 - (- 2·×3.9 ) = 13.8

s = 13.8/6 = 2.3

s = 2.3

r - s + 3·t = 10.

Therefore;

r - 2.3 + 3×3.9 = 10.

r = 10 - 9.4 = 0.6
