Given: m B = 33°; b = 12.5; mC = 67° Find c.​

Answer:

Choice A: there is insufficient evidence to conclude that the mean for the fiber content is less than 2.5 gms.

Step-by-step explanation:

From the graphs given the more appropriate is one sample t- test

One sample t- test is used and the results are

Hypothesis Test                       Fiber

Sample Mean                          2.62

Sample St. Dev                       3.492

Degrees of Freedom              24

t- test statistic                         0.1718

p- value                                    0.5675

the critical region for this test at ∝= 0.05 is t < -1.711

There is not enough evidence to reject the null hypothesis.

Since the calculated t=   0.1718 does not fall in the critical region the null hypothesis is accepted that the mean fiber content is not  less than 2.5 grams.T

Hello! answer: A. 12 × 1/11

Answer:

A

Step-by-step explanation:

THE ANSWER IS 110 m

Workers had repaired 3/4 of the road

it means3/4×440 is been repaired

length of repaired road is 3×110 = 330m

length of unrepaired road = Length of to road - length of repaired road

i.e. = 440-330 = 110m

Answer:

30 m vertically and 10 horizontally for a rectangle in a corner of the warehouse.

answer: -3

remember the equation y = mx + b

m is the slope, and b is the y-intercept

so in the equation y = 4x - 3,

4 replaces the m as the slope and -3 replaces b for the y-intercept

so -3 is your answer

Step-by-step explanation:

Answer:

A) t=0.2(60.5)

B) d=0.15(34)

C) t=0.9(157.3)

D) p=100(10.49/58.25)

E) t=0.85(94.2+0.2(94.2))

Step-by-step explanation:

A)

Let the tip be represented by t. The tip is 20% of $60.50:

t=0.2(60.5)

B)

Let the money they save be represented by d. Their discount is 15% of $34:

d=0.15(34)

C)

Let the new total be represented by t. Their discount is 10%, so they will only be paying 90% of $157.30t:

t=0.9(157.3)

D)

Let the percentage be represented by p. The tip is $10.49, to find this as a precent of the $58.25 bill, divide the tip by the bill and multiply by 100:

p=100(10.49/58.25)

E)

First find the total after the tip but before the coupon.

Their tip is 20% of $94.20, and their total before the coupon is $94.20 plus the tip: 94.2+0.2(94.2)

Now find their final total.

Let the final total be represented by t. The discount is 15%, so they will only be paying 85% of the total after tip:

t=0.85(94.2+0.2(94.2))

Answer:

-224

Step-by-step explanation:

Geometric sequence is given by An = A*R^(n-1)

Given A7 = 7 and A10 = -56

A10/A7 = -8 = R^(10-7)

R^3 = -8

R = -2

A12 = A10*R^2

= -56*-2^2

= -224

Answer:

Step-by-step explanation:

A7 = 7

A10 = -56

7xRxRxR = -56

R = -2

A12 = A10xRxR

= -56 x -2 x -2

= 224

Answer:

2,304 years old

Step-by-step explanation:

Given: Jennifer age = 18, Invested = $1000 at 8% interest

To find: How old would she be when the account is $128,000?

Wrong solution

Solution: To figure out how old she will be when her account is $128,000, simply find the difference between her current account value by her current age, by dividing. Then multiply the result by the future account value.

Step 1: [tex]\frac{1000}{18} = 55.5555555556[/tex]

Rounding, that is; 55.56

Step 2: Now, multiply the result by the future account value.

[tex]55.56[/tex] × [tex]128000 = 7111680[/tex]

Correct solution

Solution: To find out how old she will be when her account is $128,000, set up a fraction;

[tex]\frac{1000}{8} = \frac{12800}{x}[/tex]

Step 1:  Divide the numbers

[tex]\frac{1000}{8} = \frac{128000}{x} \\\\\frac{500}{9} = \frac{128000}{x}[/tex]

Step 2: Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{500}{9} = \frac{128000}{x} \\\\x * \frac{500}{9} = x * \frac{128000}{x}[/tex]

Step 3:  Cancel multiplied terms that are in the denominator

[tex]x *\frac{500}{9} = x * \frac{128000}{x} \\\\x * \frac{500}{9} = 128000[/tex]

Step 4: Re-order terms so constants are on the left

[tex]x * \frac{500}{9} = 128000\\\\\frac{500}{9} x= 128000[/tex]

Step 5: Combine multiplied terms into a single fraction

[tex]\frac{500}{9} x = 128000\\\\\frac{500x}{9} = 128000[/tex]

Step 6: Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{500x}{9} = 128000\\\\9 * \frac{500x}{9} = 9 * 128000[/tex]

Step 7: Cancel multiplied terms that are in the denominator

[tex]9 * \frac{500x}{9} = 9 * 128000\\500

Answer:

(x + 2)² + (y + 2)² = 0.75²

Step-by-step explanation:

Standard form

(x - h)² + (y - k)² = r²

the center is (h, k) = (-2, -2)

the radius is r = 0.75

(x + 2)² + (y + 2)² = 0.75²

Answer:

(x + 2)^2 + (y + 2)^2 = 0.5625

Step-by-step explanation:

By looking at the graph, we can see the center of the circle is (-2, -2) and by counting the squares, the radius is 0.75.

The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius.

We can substitute our values in to get:

(x + 2)^2 + (y + 2)^2 = 0.5625

Answer:

426 ft^2.

Step-by-step explanation:

It area = area of the rectangle + area of the triangle

= 15 * 26 + 1/2 * 8 * 9

= 390 + 1/2*8*9

= 390 + 36

= 426 ft^2.

The area of the figure given is 426 ft^2.

Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.

Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.

Area = Area of the rectangle + Area of the triangle

Area = 15 * 26 + 1/2 * 8 * 9

Area = 390 + 1/2*8*9

Area = 390 + 36

Area = 426 ft^2.

Therefore, the area of the figure given is 426 ft^2.

Answer:

y = -5/4x + 2 1/4

Step-by-step explanation:

you would start by changing the equation to point intercept form

4x + 1 = 5y

4/5y + 1/5 = y

then you fill in the points and change the slope to -5/4 (reciprocal and opposite sign)

-4 = -5/4(5) + b

-4 = -6.25 + b

2.25 = b
