Complete question is;

Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find the probability that a randomly selected student scored less than 218.

Answer:

0.93

Step-by-step explanation:

We are given;

Mean; μ = 200

Standard deviation; σ = 12

Random value; x¯ = 218

Z-score formula is;

z = (x¯ - μ)/σ

z = (218 - 200)/12

z = 18/12

z = 1.5

From z-table, attached, probability = 0.93

Answer:

y = 70 degrees

x = 11

Step-by-step explanation:

The side opposite x + 2 is equivalent so they will both be equal to 13.

To get the meaning of x, simply subtract 2 from 13 giving you x = 11.

Y is across from corner C, which is 70 degrees. These angles are equivalent to each other, meaning that angle y is also 70 degrees.

Hope this helps you :)

Answer:

x = 11

y = 70°

Step-by-step explanation:

x + 2 = 13

The lines on each side are corresponding.

11 + 2 = 13

Y is corresponding with the 70° corner.

That means the corresponding corner (y) is also 70°.

The total surface area of the block is 32.6 square inches.

Given that, Jake has a block shaped like the prism shown in a set of toys.

To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.

The total surface area of a prism = (2 × Base Area) + (Base perimeter × L).

Here, area = 2 ×1/2×2×2.3 +(2+2.5+2.5)×4

= 4.6+28

= 32.6 square inches

Therefore, the total surface area of the block is 32.6 square inches.

Givens

L = 4 units

w*h = 2 1/8 units^2

V=L* (w*h)

V = 4 * (2 1/8)

V = 8 1/2

Where did the 1/2 come from?

You could write 2 1/8 as 2 + 1/8 and use the distributive property.

4(2 + 1/8)

4*2 + 4 * 1/8

8 + 4/8

4/8 = 1/2

Answer:

∠ PTQ = 70°

Step-by-step explanation:

The angles subtended by the radii and tangents to the circle , sum to 180°

∠ PTQ + 110° = 180° ( subtract 110° from both sides )

∠ PTQ = 70°

Answer:

384 cm^2

Step-by-step explanation:

A = 6a^2    (a = side length)

A = 6(8^2)

A = 6(64)

A = 384 cm^2

More explain stuff:

a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D

Answer:

235 cm²

Step-by-step explanation:

Find area of the large rectangle on the bottom. To do that, find its length and width, then multiply them together.

Length of big rectangle=20 cm

Width of big rectangle=9 cm

20x9=180 cm²

Next, find the area of the small rectangle on the top. To do that, find its length and width, then multiply them together.

Length of small rectangle=11 cm

Width of small rectangle=5 cm

I found the width by subtracting 9 from 14, since the 9 cm is part of the large rectangle.

11x5=55 cm²

Add the areas of the two rectangles.

55+180=235 cm²

Step-by-step explanation:

OK, first draw the line y=4.

It's a bit misleading- where you think 4 should go is actually 2!

Check the scale and draw down where the two points meet on the line. They should be the same.

You get -1.7 and 1.7

Answer: $42

Step-by-step explanation:

Since the trampoline was originally priced at $100 but went on sale for 60%, the price paid will be:

= $100 - (60% × $100)

= $100 - (0.6 × $100)

= $100 - $60

= $40

Emmett bought the trampoline and then paid 5% sales tax, the total amount paid will be:

= $40 + (5% × $40)

= $40 + (0.05 × $40)

= $40 + $2.

= $42

She paid $42 in total.

The solution of the equation 36⁶x - 1 = 6⁵x is  x = 1/2176774560.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

We have the equation:

36⁶x - 1 = 6⁵x

Simplifying,

(6²)⁶x - 1 = 6⁵x

6¹²x - 6⁵x = 1

2176782336x - 7776x = 1

x = 1/2176774560

The above equation is the required solution.
