VOLUME!! *last question*

Answer:

$98.4.

Step-by-step explanation:

Since the university has decided that for the following year lecture costs will increase by 20%, workshop costs by 10%, and examination costs will stay the same, and that for level 2 the current hourly costs are 10, 24, and 60 respectively To determine how much the level 2 course cost in the following year, the following calculation must be performed:

10 x 1.2 + 24 x 1.1 + 60 = X

12 + 26.4 + 60 = X

98.4 = X

Thus, the level 2 course will cost $ 98.4 next year.

Step-by-step explanation:

I think that's the answer

I can't confirm anything

Answer:

y=2 and x=1

Step-by-step explanation:

sub 2 into 1

3(15-7y) + 4y= 11

45 - 21y +4y =11

-21y+4y= 11-45

-17y= - 34

y=2

Therefore sub y into x equation

x=15-7(2)

x= 1

Answer:

3x + 4y = 11

x = 15 -7 y

3 (15-7y) = 11

45 - 21y + 4y = 11

45 - 17 y = 11

-17 y =11 -45

-17y ÷ -17 = -34 ÷ -17

y = 2

x = 15 - 7y

x = 15 - 7(2)

x = 15 - 14

x = 1

there for y = 2 and x = 1 is the solution

Answer:

A

Step-by-step explanation:

Hello There!

The y value of ABC was subtracted by 7 to get to the figure A'B'C'

So the rule for the given transformation would be

(x,y) ---> (x,y-7)

The answer is that there are 4 sprites. Because eight is half of sixteen so i add the numerator together and 2+2=4

Answer:

same question, you  can solve this like this

The key features of the quadratic function are

From the question, we have the following parameters that can be used in our computation:

y = -x² + 4x - 3

A quadratic function is represented as

y = ax² + bx + c

By comapring the equations, we have

a = -1, b = 4 and c = -3

For the key features

Axis of symmetry: x  = -b/2a

So, we have

x  = -4/(2 * -1)

x  = 2

The domain of the function is the set of all real values

For the vertex, we have

(h, k) = (symmetry, f(symmetry))

So, we have

y = -2² + 4(2) - 3

y = 1

So, the vertex is (2, 1)

Answer:A

Step-by-step explanation:

Answer:

9). x = 36.9°

10). x = 18.3°

Step-by-step explanation:

9). By applying tangent rule in the given triangle,

   tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

   tan(x) = [tex]\frac{9}{12}[/tex]

   x = [tex]\text{tan}^{-1}(\frac{3}{4})[/tex]

   x = 36.87°

   x = 36.9°

10). By applying sine rule in the given triangle,

   sin(x) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

   sin(x) = [tex]\frac{11}{35}[/tex]

   x = [tex]\text{sin}^{-1}(\frac{11}{35})[/tex]

   x = 18.32

   x ≈ 18.3°

Answer:

80%

Step-by-step explanation:

Because the answer is 80%

Answer:40 percent

Step-by-step explanation:Total number of fruit in a bowl is 15 pieces.

Number of apples are 6 pieces in a bowl.

6/15 times 100 equals 40%

The answer in this picture is B(143)

Answer:

A

Step-by-step explanation:

180 _80 =100

180_65= 115

180_72 = 108

Then :

108 + 115 + 100 = 323

Then :

360 _ 323 = 37

Then :

180 _37 = 143

X _7 =143

X =150

Answer:

B. 3(2x+1)(x-2)

Step-by-step explanation:

For this case we have the following trinomial:-

6x^2-9x-6

Rewriting we have:-

3(2x^2-3x-2)

Factoring we have:-

3(2x+1)(x-2)

The average is the sum of the numbers divided by the quantity of numbers.

-100 + 102 =2

2/2 = 1

The average is 1

Answer:

1

Step-by-step explanation:

To find average, add up all of the numbers and divide it by how many numbers there are.

[tex]\frac{-100+102}{2} = \frac{2}{2} =1[/tex]

Answer:

The 95% confidence interval for the difference between the mean yields for the two types of fertilizer is approximately 92.5536 pounds < [tex]\bar{x}_{1}- \bar{x}_{2}[/tex] < 35.39 pounds

Step-by-step explanation:

The harvest from each plot treated with fertilizer A and fertilizer B are presented as follows;

Fertilizer A

445, 510, 464, 472, 441, 480, 403, 460, 448, 457, 437, 505, 417

Fertilizer B

398, 380, 368 393, 424, 387, 378, 415

The number of trials of fertilizer A, n₁ = 13

The number of trials of fertilizer B, n₂ = 8

The confidence level = 95%

α = 1 - 0.95 = 0.05

∴ α/2 = 0.025

The degrees of freedom, df = 8 - 1 = 7

[tex]t_{\alpha /2}[/tex] = 2.365

From Microsoft Excel, we get;

The standard deviation of the pounds of harvested fruits for the plots treated with fertilizer A s₁ = 30.71603

The mean of the pounds of harvested fruits for the plots treated with fertilizer A, [tex]\overline x_1[/tex] = 456.8462

The standard deviation of the pounds of harvested fruits for the plots treated with fertilizer B s = 18.99201

The mean of the pounds of harvested fruits for the plots treated with fertilizer B,  [tex]\overline x_2[/tex] = 392.875

The 95% confidence interval, C.I. for the difference between the mean yields for the two types of fertilizer can be constructed with the following formula

[tex]C.I. = \left (\bar{x}_{1}- \bar{x}_{2} \right )\pm t_{\alpha /2} \cdot \sqrt{\dfrac{s_{1}^{2}}{n_{1}}+\dfrac{s_{2}^{2}}{n_{2}}}[/tex]

By variable substitution, we get;

[tex]C.I. = \left (456.8462- 392.875 \right )\pm 2.635 \times \sqrt{\dfrac{30.71603^{2}}{13}+\dfrac{18.99201^{2}}{8}}[/tex]

The 95% confidence interval for the difference between the mean yields for the two types of fertilizer [tex]C.I. \approx 63.9712 \pm28.5824[/tex], which can be expressed as 92.5536 lbs. < [tex]\bar{x}_{1}- \bar{x}_{2}[/tex] < 35.39 lbs.

Answer: 16.2 ft

Step-by-step explanation:

Using the Pythagorean theorem, if we let the length of the ladder be x,
