First multiply inside the brackets:

-.5 x -1/4 = 0.125

Now multiply by 12%

0.125 x 0.12 = 0.015

answer: 0.015

Answer:

0.015

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

95% confidence interval is obtained using the following formula

COnfidence interval lower bound = mean - critical value * sigma/sq rt n

and upper bound = mean + critical value*sigma/sq rt n

Thus margin of error = critical value*sigma/rt n

varies indirectly as n provided others are remaining the same.

Hence lower sample indicates higher margin of error

Out of 4 options given we find that I option has maximum margin of error as 21%

Hence option A is most likely coming from a small sample

Given :

48°

90°{boxed like shape}

{sum of angles of triangle}

~Tulpe⚘

Answer:

x = 42°

Step-by-step explanation:

Given that,

→ A = 48°

→ B = 90°

→ C = x

Formula we use,

→ A + B + C = 180°

Let's solve for the value of missing angle,

→ A + B + C = 180°

→ 48° + 90° + x = 180°

→ 138° + x = 180°

→ x = 180° - 138°

→ [ x = 42° ]

Hence, value of missing angle is 42°.

Answer: 480 sq ft

Step-by-step explanation:

for two rectangles on right do 8*16 =128*2 = 256

the rectangle on the right is also 128

total of all rectangles is 384 ft

now for the triangles

formula: 1/2 b*h

1/2 * 16*6 = 48

multiply that by 2 for both triangles

you have 96

add that to total and you get

480 sq ft

Answer:

Step-by-step explanation:

The hypotenuse of the triangles is the length of the rectangles so the length of the rectangles is 16 ft. The width of the rectangles is 8 ft. There are 3 rectangles so the surface area of them is:

(16*8)*3 = 384[tex]ft^{2}[/tex]

The area of a triangle is base times height divided by two. Here, the height of the two triangles is 6 ft and the base is 16 ft. So, the area of the two triangles is:

[tex]\frac{6*16*2}{2}[/tex] = 16*6 = 96  [tex]ft^2[/tex]

Add the two areas together to get the surface area.

384[tex]ft^2[/tex] + 96[tex]ft^2\\[/tex] = 480[tex]ft^2[/tex]

Hence, the surface area of the triangular prism is 480[tex]ft^2[/tex]

Answer:

tan (A) = 1

Step-by-step explanation:

When sine and cosine are equal to each other, they have the same value. We know that tan (A) = sin (A) / cos (A). If sin (A) and cos (A) are the same, and any number divided by itself equals 1, the final answer must be tan (A) = 1.

The angle the 14 foot long wire must make with the gound is approximately 51 degrees.

A right angle triangle is a triangle that has one of its sides as 90 degrees. The situation forms two right angle triangle.

Using cosine law,

17² = 14² + 22² - 2 × 14 × 22 cos C

289 - 196 - 484 = -616 cos C

-391 = -616 cos C

divide both sides by -616

cos C = -391  / -616

cos C = 0.63474025974

C = cos⁻¹ 0.63474025974

C = 50.59929658

C = 51 degrees.

Therefore, the angle the 14 foot long wire must make with the gound is approximately 51 degrees.

Answer:

first is 1/8, second is 1/10, third is 1/15, and fourth is 1/16

Step-by-step explanation:

1/2 divided by 4 = .5/4

.5/4 = 0.125

.125 = 1/8

1. 1/8

1/5 = .2

.2/2 = .1

.1 = 1/10

2. 1/10

since 1/3 would be a repeating term, you can change 5 to 5/1

3/1 = 3

1/5 = .2

.2/3 = 1/15

3. 1/15

1/4 divided by four = 1/4 divided by 1/4

1 x 1 = 1

4 x 4 = 16

4. 1/16

Answer:

Multiplication is the process of multiplying. The total cost of the boxes of two types is $90.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The cost of the first box is $12, which has 8 pounds of milk chocolate and 4 pounds of dark chocolate.

The cost of the second box is $15, which has 5 pounds of milk chocolate and 10 pounds of dark chocolate.

Therefore, if we buy the 5 boxes of the first type and 2 boxes of the second type, then the amount of two chocolate that Tim needs will be fulfilled.

The cost of 5 boxes of the first type is $60 ($12 ×5), while the cost of 2 boxes of the second type is $30 ($15×2), therefore, the total cost of the boxes of two types is $90.

Answer:

31.4

Step-by-step explanation:

To find circumference, the formula is A=pi*r^2. The radius is 1/2 the diameter. The radius of the donut is 3.5. 3.5^2 is 12.25. Pi is approximately 3.14, so 12.25*3.14 is 38.465. The donut hole takes away from the circumference, so we have to subtract the circumference of the donut hole from the donut. 1.5^2 is 2.25, and 2.25*3.14 is 7.065. 38.465-7.065 is 31.4. The circumference of the circle is 31.4.

Step-by-step explanation:

1/10 can be converted to decimal form as 0.1.

70/100 can be converted to decimal form as 0.7

0.1 + 0.7 = 0.8

Another way is making use of a common denominator:

Common denominator --> 100

1/10 --> mutiply numerator and denominator by 10 --> 10/100

10/100 +70/100 = 80/100 = 8/10 = 0.8
