Answer:

The resulting matrix will be 11 * 7

Step-by-step explanation:

Given

Matrices 11 * 6 multiplied by 6 * 7

Required

The dimension of the resulting matrix

When a matrix a * b is multiplies by a matrix b * c, the resulting matrix will be: a * c

In this case:

[tex]a * b = > 11 * 6[/tex]

[tex]b * c => 6 * 7[/tex]

So, the resulting matrix will be:

[tex]a * c => 11 * 7[/tex]

Answer:

[tex]Rate = -2h-1[/tex]

Step-by-step explanation:

Given

[tex]f(x) = -2x^2 + 3x - 7[/tex]

[tex]Interval: [1,1+h][/tex]

Required

The average rate of change

This is calculated as:

[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]

Where:

[tex][a,b] = [1,1+h][/tex]

So, we have:

[tex]Rate = \frac{f(1+h) - f(1)}{1+h - 1}[/tex]

[tex]Rate = \frac{f(1+h) - f(1)}{h}[/tex]

Calculate f(1+h) and f(1)

[tex]f(x) = -2x^2 + 3x - 7[/tex]

[tex]f(1) = -2 * 1^2 + 3 * 1 - 7 = -6[/tex]

[tex]f(1+h) = -2 * (1+h)^2 + 3 * (1+h) - 7[/tex]

Evaluate squares and open bracket

[tex]f(1+h) = -2 * (1+h+h+h^2) + 3+3h - 7[/tex]

[tex]f(1+h) = -2-2h-2h-2h^2 + 3+3h - 7[/tex]

[tex]f(1+h) = -2-4h-2h^2 + 3+3h - 7[/tex]

Collect like terms

[tex]f(1+h) = -2h^2-4h +3h-2+ 3 - 7[/tex]

[tex]f(1+h) = -2h^2-h-6[/tex]

So, we have:

[tex]Rate = \frac{f(1+h) - f(1)}{h}[/tex]

[tex]Rate = \frac{-2h^2-h-6 - -6}{h}[/tex]

[tex]Rate = \frac{-2h^2-h-6 +6}{h}[/tex]

[tex]Rate = \frac{-2h^2-h}{h}[/tex]

Factorize the numerator

[tex]Rate = \frac{h(-2h-1)}{h}[/tex]

Divide

[tex]Rate = -2h-1[/tex]

The percentage of growth is of 9.05%.

The amount of money in the account after t years is given by [tex]P(t) = 330(1.0905)^t[/tex]

Step-by-step explanation:

Amount of money after t years:

The amount of money in an account after t years is given by:

[tex]P(t) = P(0)(1+r)^t[/tex]

In which P(0) is the initial deposit and r is the growth rate, as a decimal.

Money doubles every 8 years.

This means that [tex]P(8) = 2P(0)[/tex]. So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]2P(0) = P(0)(1+r)^8[/tex]

[tex](1+r)^8 = 2[/tex]

[tex]\sqrt[8]{(1+r)^8} = \sqrt[8]{2}[/tex]

[tex]1 + r = 2^{\frac{1}{8}}[/tex]

[tex]1 + r = 1.0905[/tex]

[tex]r = 1.0905 - 1[/tex]

[tex]r = 0.0905[/tex]

The percentage of growth is of 0.0905 = 9.05%.

Person invested $330

This means that [tex]P(0) = 330[/tex]

So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]P(t) = 330(1+0.0905)^t[/tex]

[tex]P(t) = 330(1.0905)^t[/tex]

The amount of money in the account after t years is given by [tex]P(t) = 330(1.0905)^t[/tex]

Answer:

4.8

Step-by-step explanation:

area of rectangle = lxb = 8x

area of trapezium =  (a+b)h/2 = ( x+13)6 /2 = 3x + 39

Aea of whole figure = 91.8

8x + 3x+ 39 = 91.8

11x = 91.8-39

x= 52.8 /11 = 4.8

Step-by-step explanation:

x+ y = 0  

and

-2x + 5y + 2 = 0

Step-by-step explanation:

given line

3x+5y+2=0

5x+3y-2=0

solution

when two line bisect each other then line equation of bisector is express as

  1

and here

A1 = 3

B1  = 5

C1 = 2

and

A2 = 5

B2  = 3

C2 = -2

so now put value in equation 1 we get

solve it we get

-2x + 5y + 2 = 0   1

and

3x+5y+2 = - ( 5x+3y-2 )

Answer:

Step-by-step explanation:

The future value of the investment increase will be $6,028.98.

The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.

Given:

P = $3000

R = 7%

T = 10 years

r = R/100

r = 7/100

r = 0.07 rate per year,

Then solve the equation for A

A = P[tex](1 + r/n)^{nt[/tex]

A = 3,000.00[tex](1 + 0.07/12)^{(12)(10)[/tex]

A = 3,000.00[tex](1 + 0.0058333333333333)^{(120)[/tex]

A = $6,028.98

Hence, the future value will be $6,028.98.

Answer:

Step-by-step explanation:

The population of deer at time t=3 years is approximately 4128 deer.

An exponential function is a mathematical function of the form [tex]f(x) = a^x[/tex], where a is a positive constant called the base, and x is the input variable. The exponent x represents the power to which the base a is raised.

The rate of growth of the deer population is given by the function [tex]R(t) = 2000e^{(0.231t)}[/tex], where t is the time in years since t=0.

To find the population at time t=3, we need to evaluate R(3) using the given function:

[tex]R(3) = 2000e^{(0.231\times 3)[/tex]

[tex]R(3) = 2000e^{0.693}[/tex]

R(3) ≈ 4127.72

Therefore, the population of deer at time t=3 years is approximately 4128 deer.

Step-by-step explanation:

AP Classroom says so.

The data doesn't provide convincing statistical evidence for considered proportion comparison. We deduce that: Option E: There is not convincing statistical evidence

There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test. The hypothesis which we put against null hypothesis is alternate hypothesis.

Null hypothesis is the one which researchers try to disprove.

Suppose we have:

Then, we get:

[tex]Z = \dfrac{\hat{p}_1 - \hat{p}_2}{\sqrt{\hat{p}(1-\hat{p}_1 )(\dfrac{1}{n_1} + \dfrac{1}{n_2}) }}[/tex]

If the level of significance = [tex]\alpha[/tex]critical value of Z is: [tex]Z_{\alpha/2}[/tex], and if [tex]Z > Z_{\alpha/2}[/tex]null hypothesis, else if [tex]Z_{\alpha/2} > Z[/tex] then we cannot reject it.

For this case, we want to know if  the data provides convincing statistical evidence that the proportion who would be classified as normal after one month of taking cinnamon is greater than the proportion who would be classified as normal after one month of not taking cinnamon.

Thus, we get our hypotheses as:

Null hypotheses: They don't provide convincing evidence (and thus, cinnamon had no improvement on the proportion), and thus:

[tex]H_0: \hat{p}_1 \leq \hat{p}_2[/tex]

Alternate hypothesis: Data provides convincing evidence (that the use of cinnamon made increment in considered proportion), and thus:

[tex]H_a: \hat{p}_1 > \hat{p}_2[/tex]

The test is single tailed.

For this case, we have:

Thus, we get:

[tex]Z = \dfrac{\hat{p}_1 - \hat{p}_2}{\sqrt{\hat{p}(1-\hat{p}_1 )(\dfrac{1}{n_1} + \dfrac{1}{n_2}) }} =\dfrac{0.35 - 0.25}{\sqrt{0.3(0.7 )(\dfrac{1}{40} + \dfrac{1}{40}) }} \approx 0.976[/tex]

At 0.01 level of significance ([tex]\alpha = 0.01 = 1\%[/tex]), we get the critical value of Z from z-tables as:

[tex]Z_{\alpha/2} = 2.576[/tex]

Since [tex]Z_{\alpha/2} > Z[/tex] , we cannot reject the null hypothesis, and thus, deduce that there is not convincing statistical evidence at the level of 0.01

At 0.05 level of significance ([tex]\alpha = 0.05 = 5\%[/tex]), we get the critical value of Z from z-tables as:

[tex]Z_{\alpha/2} = 1.96[/tex]

Since [tex]Z_{\alpha/2} > Z[/tex] , we cannot reject the null hypothesis, and thus, deduce that there is not convincing statistical evidence at the level of 0.05

At 0.10 level of significance ([tex]\alpha = 0.10 = 10\%[/tex]), we get the critical value of Z from z-tables as:

[tex]Z_{\alpha/2} = 1.645[/tex]

Since [tex]Z_{\alpha/2} > Z[/tex] , we cannot reject the null hypothesis, and thus, deduce that there is not convincing statistical evidence at the level of 0.10

Remember that the conclusions can be made even if they were volunteers since that doesn't make it wrong as volunteers are randomly coming out people from real population.

Thus, we deduce that: Option E: There is not convincing statistical evidence
