Answer:

7

Step-by-step explanation:

Let's call the missing card number "x".

The mean is the sum divided by the number of elements, so we know that:

[tex]\frac{12 + 6 + 15 + x}{4} = 10\\~\\12 + 6 + 15 + x = 40\\33 + x = 40\\x = 7[/tex]

The number on the 4th card is 7 according to the given question when The mean of the 4 numbers on Ed's cards is 10

To work out the number on the 4th card, we can use the information given about the mean of the four numbers.

Mean is calculated by summing all the values and then dividing by the number of values. In this case, the mean is 10 and there are four numbers.

Given:

Mean = 10

Number of cards = 4

To find the sum of the four numbers, we multiply the mean by the number of cards:

Sum of the four numbers = Mean * Number of cards

Sum of the four numbers = 10 * 4

Sum of the four numbers = 40

Now, let's find the number on the 4th card. We subtract the sum of the three known numbers from the sum of the four numbers:

Number on the 4th card = Sum of the four numbers - Sum of the three known numbers

Number on the 4th card = 40 - (12 + 6 + 15)

Number on the 4th card = 40 - 33

Number on the 4th card = 7

Therefore, the number on the 4th card is 7.

Answer:

A:1

Step-by-step explanation:

Answer:

Step-by-step explanation:

First we open the parentheses:

2*3x-2*7+18=10

Now we multiply:

6x-14+18=10

6x+4=10

Now we move +4 to the other side so it will be -4

6x=10-4

6x=6

We divide both sides by 6

x=1

Answer:

f(0) = 31

Step-by-step explanation:

We are given the following function:

[tex]f(x) = \sqrt{7x} + 31[/tex]

f(0).

This is the value of f when [tex]x = 0[/tex]. So

[tex]f(0) = \sqrt{7*0} + 31 = \sqrt{0} + 31 = 0 + 31 = 31[/tex]

So f(0) = 31

Answer:

50.24

Step-by-step explanation:

The formula for area is pi · r²

But, because usually people want it simplified instead of a ton of decimal numbers following, pi is rounded to 3.14. And the radius in this case is 4. And the ² means squared, so we have to do 4 · 4 to square it.

So, now our formula is 3.14 · 4 · 4 which equals 50.24

A circle is formed when a cone intersects a plane as shown in the drawing.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

A cross section is defined as the process where a surface is shown when a straight cut is made by something. We are given when a cone is intersected by a plane horizontally the shape of the cross - section is a circle .

When the cone is intersected vertically by a plane the shape of the cross- section will be a triangle. Hence the shape of the cross section depends according to the cut.

Cross section is usually used to find what is there inside the object.

Answer:

0.54035

Step-by-step explanation:

Given that :

Mean, m = 66 inches

Standard deviation, s = 2.5 inches

P(65 < X < 69)

P(X < 69) - P(X < 65)

((69 - 66) / 2.5) - ((65 - 66) / 2.5)

P(Z <(3/ 2.5)) - P(Z <(-1 / 2.5))

P(Z < 1.2) - P(Z < - 0.4)

0.88493 - 0.34458
