The probability of snow on Tuesday is 0.3 and on Wednesday is 0.4. Assuming these are independent, what is the probability that: It snows on both days. It does not snow on Tuesday. It snows on Tuesday, but not Wednesday. It snows on at least one of these days. It does not snow on either day.

Ron jump is less than 10 feet. Ron jump is actually 5.45 feet.

Stacey long jump was 10 feet. That is 5/6 foot longer than Ron's long jump.

Let's find if Ron jump more or less than 10 feet's.

Therefore,

Ron's Jump = x

Hence,

x + 5 / 6 x = 10

6x + 5x / 6 = 10

cross multiply

6x + 5x = 60

11x = 60

x = 60 / 11

x = 5.45

Therefore, Ron jump less than 10 feet.

Answer:

  (2, 8)

Step-by-step explanation:

You want the image coordinates of (8,-2) after 90 degree counterclockwise rotation.

The transformation of (x, y) coordinates that does a 90° CCW rotation about the origin is ...

  (x, y) ⇒ (-y, x)

Applying this transformation to the given point, we have ...

  (8, -2) ⇒ (2, 8)

The rotated point is (2, 8).

Answer: y = 4

Step-by-step explanation:

First, we have to look at the triangle and understand which sides match each other. The side measure of EF matches the side of KH. Since we know these are congruent sides, we can set them equal to each other in an equation. So,

7y - 11 = 17.00

Now we add 11 to both sides, isolating the variable.

7y = 28.00

Now, we divide by 7 on both sides.

7y/7 = 28/7

y = 4

The measure of angle B is 78°.

∠A = (2x - 9)°

∠B = (2x + 4)°

∠C = x°

In triangle ABC,

      ∠A + ∠B + ∠C = 180°

2x - 9 + 2x + 4 + x = 180

                   5x - 5 = 180

                        5x = 180 + 5

                        5x = 185

                          x = 185/5

                          x = 37

∠B = 2x + 4

     = 2*37 + 4

The equation that represents the proportional relationship is y=14x. The correct option is D.

Given the table which shows a proportional relationship X=1,2,3 and Y=14,28,42.

We want to find an equation that represents the proportional relationship.

We will find the proportional relationship by dividing Y with X.

When X=1 and Y=14 then proportional relationship is

Y/X=14/1

Multiply both sides by X, we get

(Y/X)X=14X

Y=14X.....(1)

When X=2 and Y=28 then proportional relationship is

Y/X=28/2

Y/X=14

Y=14X.....(2)

When X=3 and Y=42 then proportional relationship is

Y/X=42/3

Y/X=14

Y=14X......(3)

From equation (1),(2) and (3) we get that the proportional relationship is Y=14X.

Hence, an equation that represents the proportional relationship when the table shows a proportional relationship is Y=14X.

Slope of a Line :

The ratio of the change in the y coordinate to the change in the x coordinate is known as a line's slope in mathematics.

Y and X, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate.

As a result, the formula for the change in y-coordinate with respect to the change in x-coordinate is m = change in y/change in x = y/x.

where the slope of a line is denoted by "m".

The graph of the equation y = mx + c has a slope of m, an intercept of m, and a y-intercept of c. In the slope-intercept version of the linear equation, m and c are real integer values.

There are 12 players of right handed, according to the question.

What do you mean by percentage?

A percentage in mathematics is a number or ratio that is expressed as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, though the percent sign, "%," is most frequently used. A percentage has no dimensions and no standard measurement.

According to data in the given question,

We have given data:

A local little league has a total of 60 players of whom 20% are right-handed.

Let x be the total number of players that are right-handed.

The value of x can be found as follow:

x = 20% of 60

x = (20/100)60

x = 0.2(60)

x = 12

Therefore, the total number of players that are right-handed is 12, if the local little league has a total of 60 players of whom 20% are right-handed.

33% is the increasing percentage in the size of the graduating class.

The formula for percentage increase = Final number - Initial number x 100

                                                                              Initial number

Or, it can be also written as

Percentage increase =   Increase       x 100

                                       Initial number

Given that:

The final number of students = 266

The initial number of students = 200

Therefore, putting the value in the formula. We get,

Percentage increase = 266 - 200   x 100

                                           200

Percentage increase = 66   x 100

                                      200

The required equation is y = 14.85x + 110.25.

The slope-intercept form of a line is y = mx +c where m is the slope of the line and c is the y-intercept.

Given that, Jake collects $311.95 after receiving 21 texts.

Therefore, he collected $311.95/21 per text.

$311.95/21 = $14.85

The collection balance was $422.20, therefore, Jake already has $422.20-$311.95 = $110.25.

Let Jake receives x texts, then he will get $14.85x, and Jake already has $110.25, therefore, the total collection after receiving x texts is:

y = 14.85x + 110.25

Hence, The required equation is y = 14.85x + 110.25.

After the subtraction, the simplified form of the mixed number is 33/4

Mixed numbers

Mixed fraction means a fraction represented with its quotient and remainder.

Given,

Here we have the mixed numbers 12 5/12 - 4 1/6

Now, we have to perform the subtraction in it and then we have to simplifies it.

Firs we have to convert the mixed numbers into normal fraction, for that we have to do the following:

12 5/12 = (12 x 12) + 5/12

=> (144 + 5)/12

=> 149/12

Similarly, when we simplifies the second one, then we get,

=> 4 1/6 = (6 x 4) + 1/6

=> (24 + 1) / 6

=> 25/6

Here the fractions have unlike denominators.

So, first we have to find the Least Common Denominator and rewrite the fractions with the common denominator.

Therefore, the LCD(149/12, 25/6) = 12

Now, we have to multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD.

=> 149/12 - 50/12

The two fractions now have like denominators so you can subtract the numerators.

Then:

=> 99/12

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 99 and 12 using GCF(99,12) = 3

So, the simplified form of the fraction is

Answer:

Step-by-step explanation:

first add inside the parentheses 4+7=11

then add three 11+3=14

Answer: 3 + 11 = 14

Step-by-step explanation: Follow PEMDAS (Parentheses, exponent, multi, divi, add, subtract.)

Step-by-step explanation:

since it is a right-angled triangle, the principle of Pythagoras has to be fulfilled :

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), which is in our case (x + 32).

a and b are the legs.

so

(x + 32)² = x² + (x + 31)²

x² + 64x + 1024 = x² + x² + 62x + 961

2x + 1024 = x² + 961

x² - 2x - 63 = 0

as 63 = 7×9

and -9 + 7 = -2

we can conclude that this quadratic equation is the same as the following factorization :

(x + 7)(x - 9) = 0

we have 2 solutions :

x = -7

x = 9

as x is also the length of a side, the negative solution does not make any sense.

so, x = 9 is our solution.

that means the sides of the triangle are

x = 9

x + 31 = 40

x + 32 = 41

and the perimeter of the triangle is

9 + 40 + 41 = 90
