The critical value for a 0.05 level of significance is 1.96, so the calculated t-test statistic (-1.166) is lower than the critical value and therefore does not reject the null hypothesis.

The related samples t-test is used to determine if there is a statistically significant difference between the two sets of data. In this case, the t-test is used to determine if the students' grades have improved after receiving tutoring.

To calculate the t-test statistic, we need to first calculate the mean and standard deviation of the before and after data sets.

For the before data set, the mean is 2.56 and the standard deviation is 0.8. For the after data set, the mean is 3.22 and the standard deviation is 0.5.

We can then calculate the t-test statistic using the following formula:

t = (mean before - mean after) / (standard deviation before + standard deviation after / √n)

where n is the number of samples.

In this case, n = 5, so the t-test statistic is:

t = (2.56 - 3.22) / (0.8 + 0.5 / √5) = -1.166

Answer: Part A:

If Isabella's mother has a garden with an area of 10 2/3 square feet, and she plants peas in 1/4 of the garden, we can calculate the area used for planting peas by multiplying the garden area by 1/4:

Area used for planting peas = (10 2/3 square feet) x (1/4) = (32/3) x (1/4) = 8/3 square feet

Therefore, the area used for planting peas is 8/3 square feet.

Part B:

If Isabella's mother sells the peas and gets 3 dollars for each square foot, we can calculate how much money she made by multiplying the area used for planting peas by 3:

Money made = (8/3 square feet) x (3 dollars/square foot) = 8 dollars

Therefore, Isabella's mother made 8 dollars by selling the peas she planted in her garden.

Answer:

x=16.3

Step-by-step explanation:

sine: opposite side ÷ hypotenuse

sine(x)= 7 ÷ 25 = 0.28

sine^-1(0.28) = 16.3

x = 16.3

Answer:

16.3 rounded to the nearest tenth

Step-by-step explanation:

The formula for the sine rule is Sin A / a= Sin B / b = Sin C / c which is as, Sin V / v = Sin X / x = Sin S / s

Sin 90 / 25 = Sin X / 7, that is,

1 / 25 = Sin X / 7 (cross multiply)

Make Sin X the subject of the formula;

Sin X = 7 / 25

X = Sin^-1(7 / 25)

X = 16.26 = 16.3 rounded to the nearest tenth

Answer:

144 in^3

Step-by-step explanation:

You need to separate the figure into the top and bottom rectangles

As a result, the answer to the following question, Rectangle area minus inner rectangle area minus total area of little rectangles = 84 - 30 - 16 = 38 square inches.

An area is the size of a surface area. The surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a planar region or planar region refers to the area of a form or flat layer. The area of an item is the entire amount of space occupied by its planar (2-D) surface or form. Using a pencil, draw a square on a sheet of paper. A two-dimensional character. The area of a form on paper is the amount of space it occupies. Assume that the square is made up of smaller unit squares.

Rectangle area = length x breadth = 12 x 7 = 84 square inches

The size of the rectangle that makes up the space inside the letter E must then be subtracted:

5 × 6 = 30 square inches is the area of the inner rectangle.

A tiny rectangle's area 5 x 1 = 5 square inches = 1 = length x width

A tiny rectangle's area 5 x 1 = 5 square inches = 2 = length x width

A tiny rectangle's area 2 x 3 = 6 square inches = 3 = length x width

5 + 5 + 6 = 16 square inches is the total area of little rectangles.

Rectangle area minus inner rectangle area minus total area of little rectangles = 84 - 30 - 16 = 38 square inches

Answer:

1440 ft²

Step-by-step explanation:

The roof is made up of 4 congruent triangles.

We first solve for the area of one of the triangles using the formula:

A = (1/2) · b · h

↓ plugging in given values

A = (1/2) · 40 ft · 18 ft

A = 20 ft · 18 ft

A = 360 ft²

Now, we can solve for the surface area of the entire roof by multiplying the area of one of the triangles by 4 (because there are 4 congruent triangles).

SA = 360 ft² · 4 = 1440 ft²

—

Note that we can solve for the area of the triangles using the formula {A = (1/2) · b · h} because the slant height of a pyramid is perpendicular to the side of the pyramid's base that it connects to, thereby making it the height of the triangle that is the pyramid's side.

Step-by-step explanation:

First we sould factor out the function:

y=x^2+5x-6

y=(x+6)(x-1)

Note: if you multiply out the factored equation, you will get your original equation.

Now, find what we need to plug in to make it equal 0.

If we plug in -6, then the (x+6) part equals 0. Since we are multiplying by 0, the whole thing equals 0.

If we plug in 1, then the (x-1) part equals 0. Since we are alo multiplying by 0 here, the function comes out to 0.

This means that at x=-6 and x=1 the function comes out to 0.

Answer:

one apple: 75 cents

one orange: 60 cents

Step-by-step explanation:

let x be price of one apple

let y be price of one orange

3x + 4y = 4.65

5x + 8y = 8.55

we can do elimination, substitution, or graphing.

this is elimination: (we're eliminating the x in this case to find y, and then use y to find x)

ORIGINAL EQUATIONS: (we're multiplying by 5 so we can eliminate x)

3x + 4y = 4.65

5x + 8y = 8.55

5(3x + 4y = 4.65) = 15x + 20y = 23.25

3(5x + 8y) = 8.55 = 15x + 24y = 25.65

(distribute, and then subtract to get one equation and eliminate x)

  15x + 20y = 23.25

-  15x + 24y = 25.65

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

  0    -    4y = - 2.4

so we got that, now we make it this:    -4y = -2.4

divide both sides by -4.

-4y = -2.4

-----    -----

-4          -4

y (orange variable) = 0.60

therefore, one orange cost 60 cents.

plug y (the 60 cents) back into one of the original equations (either works) and solve for x.

3x + 4y = 4.65

5x + 8y = 8.55

let's use this equation:  5x + 8y = 8.55

5x + 8(0.6) = 8.55

5x + 4.8 = 8.55

     -4.8      -4.8

5x = 3.75

----    ------

5        5

x = 0.75

therefore, one apple cost 75 cents.

(also, there was an easier number to multiple the equations by)

3x + 4y = 4.65

5x + 8y = 8.55

We could have multiplied (3x + 4y = 4.65) with 2, distributing and bringing it to 6x + 8y = 9.30

Then subtract 6x + 8y = 9.30 from 5x + 8y = 8.55, and you would have solved and gotten x just fine, then plugged x back in to find y)

Answer:

Step-by-step explanation:

The total amount paid at the end of sixth month is S/78,000. So, the correct answer is (b).  Total amount paid at the end of the nth month is 24,000n + 9,000. So, the correct answer is (b). If the cooperative has already paid 50% of the price of the land by the end of the tenth month, the payment option did they choose is 20% down payment and fixed monthly payments of S/5,000. So, the correct option is (a).

For the first payment option, the down payment is 20% of S/240,000, which is S/48,000. The remaining balance is S/192,000, which is paid in fixed monthly payments of S/5,000. Therefore, at the end of the sixth month, the total amount paid is:

S/48,000 + 6 x S/5,000 = S/78,000

So, the answer is (b) S/78,000.

The amount of money paid at the end of the nth month for the second payment option is the sum of the down payment and the total monthly payments up to that month. The down payment is 10% of S/240,000, which is S/24,000. The total monthly payments up to the nth month is S/9,000 x n. Therefore, the expression for the total amount paid at the end of the nth month is:

S/24,000 + S/9,000 x n = (3S + 8n)/72

So, the answer is (b) 24,000n + 9,000.

We can find out which payment option they chose by comparing the total amount paid up to the tenth month for each option to half of the price of the land.

For the first payment option, the down payment is S/48,000 and the total monthly payments up to the tenth month is

10 x S/5,000 = S/50,000.

Therefore, the total amount paid up to the tenth month is:

S/48,000 + S/50,000 x 10 = S/480,000/25

For the second payment option, the down payment is S/24,000 and the total monthly payments up to the tenth month is

10 x S/9,000 = S/9,000.

Therefore, the total amount paid up to the tenth month is:

S/24,000 + S/9,000 x 10 = S/24,000 + S/900

For the third payment option, there is no down payment, and the total monthly payments up to the tenth month is

10 x S/12,000 = S/1,200.

Therefore, the total amount paid up to the tenth month is:

S/1,200 x 10 = S/12,000

Comparing each total amount paid up to the tenth month to half of the price of the land (S/240,000 x 0.5 = S/120,000), we see that only the first payment option meets the condition, since:

S/480,000/25 < S/120,000

Therefore, the answer is (a) First.

Step-by-step explanation:

The area of the rectangle in mixed fraction form is 11(17/21) cm².

What is fraction?

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

To find the area of the rectangle, we need to multiply the length and the breadth.

We can convert the mixed numbers to improper fractions and then multiply  -

Length = 2(2/7) cm = (7×2+2)/7 = 16/7 cm

Breadth = 5(1/6) cm = (6×5+1)/6 = 31/6 cm

The formula for area of rectangle is -

Area = Length × Breadth

Substitute the values in the equation -

= (16/7) cm × (31/6) cm

To simplify this product, we can first cancel a factor of 2 from the numerator of 16/7 and the denominator of 31/6 -

Area = (8/7) cm × (31/3) cm

Now we can multiply the numerators and denominators separately -

Area = (8 × 31) / (7 × 3) cm²

Area = 248/21 cm²

To write this as a mixed number, we can divide 248 by 21 -

248 ÷ 21 = 11 with a remainder of 17

So the area can be expressed as the mixed number -

11(17/21) cm²

Therefore, the area value is obtained as 11(17/21) cm².
