What number does this model show?

9514 1404 393

Answer:

  314 square inches

Step-by-step explanation:

The radius is half the diameter. If the diameter is 20 inches, the radius is 20/2 = 10 inches. The area is given by the formula ...

  A = πr²

Filling in the given values, we get ...

  A = 3.14×(10 in)² = 314 in² . . . . area of the circle

Answer:

  arc AC = 63°

Step-by-step explanation:

Arc BC is twice the measure of inscribed angle BAC, so is ...

  arc AC = 2×89° = 178°

The remaining arc of the circle is the difference between 360° and the sum of the other two.

  arc AC = 360° -119° -178°

  arc AC = 63°

Probability[Number of 6 random sample do not have cavities] = 0.8

Step-by-step explanation:

Given:

Number of student do not have cavities = 60%

Number of random sample = 9 children

Find:

Probability[Number of 6 random sample do not have cavities]

Computation:

n = 9

p = 60% = 0.6

P(At least 6)  

Probability[Number of 6 random sample do not have cavities] = 1 - P(Less than 6)  

Probability[Number of 6 random sample do not have cavities] = 1 - P(Less than or equal to 6)

Probability[Number of 6 random sample do not have cavities] = 0.8

The probability of 9 children selected from this school, at least 6 do not have cavities is 0.80.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Sixty percent of all children in a school do not have cavities.

The probability, rounded to four decimal places, that in a random sample of 9 children selected from this school, at least 6 do not have cavities will be

n = 9

p = 0.60

Then we have

[tex]\rm P = 1 - P(less \ than \ or \ equal \ 6)\\\\P = 0.8[/tex]

Answer:

The probability that, in successive drawing of chips, the colors of the first four chips alternate = 0.0751

Step-by-step explanation:

Step 1:

The probability that, in successive drawing of chips, the colors of the first four chips alternate, can occur in two ways: RED-WHITE-RED-WHITE (RWRW) or WHITE-RED-WHITE-RED (WRWR).

Step 2:

Given that an urn contains three white and four red chips and that each time we draw a chip, we look at its color. If it is red, we replace it along with two new red chips, and if it is white, we replace it along with three new white chips.

Probability of RWRW is given as follows:

Probabilty of the first being a red = 4/7

Probability of the next being a white = 3/9 = 1/3

Probability of the next being a red = 6/12 = 1/2

Probability of the next being a white = 6/14 = 3/7

Thus, probability of RWRW = 4/7 × 1/3 × 1/2 × 3/7 = 0.0408

Probability of WRWR is given as follows:

Probabilty of the first being a white = 3/7

Probability of the next being a white = 4/10 =2/5

Probability of the next being a red = 6/12 = 1/2

Probability of the next being a white = 6/15 = 2/5

Thus, probability of WRWR = 3/7 × 2/5 × 1/2 × 2/5 = 0.0343

Step 3:

Probability of RWRW or WRWR = 0.0408 + 0.0343 = 0.0751

Therefore, the probability that, in successive drawing of chips, the colors of the first four chips alternate = 0.0751

Answer:

y = 27

Step-by-step explanation:

y/3 + 2 = 11

First subtract 2 from each side

y/3 + 2-2 = 11-2

y/3  = 9

Then multiply each side by 3

y/3 *3 = 9*3

y = 27

Answer:

Answer is below :)

Step-by-step explanation:

y/3 + 2 = 11 is the Expression

Only two steps:  

step 1 = subtract 2 from both the sides

y/3 = 9

Step 2 = multiply 3 from both sides

y = 27

Answer:

Step-by-step explanation:

Y-intercept of line is 14

slope of line = (0 - 14)/(10 - 0) = -14/10 = -7/5

Required equation is y = -7/5 x + 14

Answer:

y=3x-4

Step-by-step explanation:

The slope-intercept form of the equation of a line is written in y=mx+b

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

So in that form

y=mx+b  becomes

y=3x-4 using your slope of 3 and y-intercept of -4

Answer:

96.25

Step-by-step explanation:

A ztable gives us values for P(X<x) and we're looking for P(X>x) so by the rule a symmetry we must make the value negative

Go to a ztable and find the value closest to .6 (I get .25), make this negative and let's set up our equation

-.25=(x-100)/15

solve for x

-3.75=x-100

x=96.25

Answer:

D

Step-by-step explanation:

If x is the game number, and y is the amount of touchdown passes for that specific game number, then (5,3) represents the idea that the quarter back threw y = 3 touchdown passes for game number x = 5

So the answer is choice D. This is the only ordered pair that comes from the given table. Something like (2,4) isn't true because the quarterback threw 1 touchdown pass (not 4) in game two.

Answer:

y  =  [tex]\frac{-8}{3}[/tex]x + [tex]\frac{62}{3}[/tex]

Step-by-step explanation:

Use slope formula.

then substitute slope for m in y = mx + b

pick a set of coordinates and substitute them in for x and y.

Solve for b

Answer:

[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the points (7,2) and (10,-6)

[tex]m=\frac{2-(-6)}{7-10}\\m=\frac{2+6}{7-10}\\m=\frac{8}{-3}[/tex]

Therefore, the slope of the line is [tex]-\frac{8}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\frac{8}{3}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\frac{8}{3}x+b[/tex]

Plug in one of the given points and solve for b

[tex]2=-\frac{8}{3}(7)+b\\2=-\frac{56}{3}+b[/tex]

Add [tex]\frac{56}{3}[/tex] to both sides to isolate b

[tex]2+\frac{56}{3}=-\frac{56}{3}+b+\frac{56}{3}\\\frac{62}{3}=b[/tex]

Therefore, the y-intercept is [tex]\frac{62}{3}[/tex]. Plug this back into [tex]y=-\frac{8}{3}x+b[/tex]:

[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]

Answer:

112 yards

Step-by-step explanation:

Applying Pythagoras theorem,

Pythagoras theorem states that, in a right angle triangle, the square of the hypotenuse is equal to the sum of the square of the two other sides.

Mathematically, it is expressed as

a² = b²+c²................. Equation 1

Where a = Length of the diagonal, b and c = lenght of the two other sides

From the question,

Given: b = 50 yards, c = 100  yards.

Substitute these values into equation 1

a² = 50²+100²

a² = 2500+10000

a² = 12500

a = √12500

a = 111.8

a = 112 yards

5. 20 = 8 (square) + 8 (square) + 4

6. 20 = 5 (square) × 4

7. 20 = 2 × 20 (square) - 20 (square)

8. 20 = 60 ÷ 3 (circle)

9. 8 × 6 = 39 + 9 (circle)

10. 7 × 6 = 49 (square) - 7 (circle)

11. The problems with 2 of the same shape,

    and problems with only one shape,

    The problems with two alike shapes means that, since they have to be

    the same number, there is no room for modification, or increasing the

    value of one shape and subtracting the same transformation from the

    other.

    With problems #6, #8 and #9, the singular shapes work as a variable in

    an expression, with usually only one making the identity true.
