Answer:

235.4

Step-by-step explanation:

7% more than 220 would be 235.4

First you would turn 7% as a decimal which would be .07. Then, you would multiply .07 times 220 which would give you 15.4. Lastly, you would add 15.4 plus 220 which would equal 235.4.

7%=.07

.07×220=15.4

The value of n which is a constant representing number of innings is equal to 50.

What is ERA or earned run average ?

Earned runs without the help of passed ball, are represented by the earned run average, which is the number of earned runs a pitcher allows per nine innings.

It is given that In 2020, the pitcher had an ERA of 2.70.

A rate of earned runs to a fixed number of innings, n, which is also known as ERA.

Let's check it.

To determine a pitcher's earned run average or (ERA), multiply the runs by nine, then divide it by the number of innings pitched.

The runs earned in 2020 is 15 , let's multiply it by 9.

So , we get 15 × 9 = 135.

Now , divide it by number of innings which is 50.

So , the value of ERA will be equal to : 135 ÷ 50 = 27 which is also given in the question.

Now we will calculate the value of n.

So ,

n = (9 × Earned runs) / ERA

or

n = ( 9 × 15 ) / 2.7

n = 135 / 2.7

n = 50 innings

Therefore , value of n which is a constant representing number of innings is 50.

By using normal distribution, we get probability of gains between 0kg to 3kg is 0.2547

What is normal distribution?

A probability distribution known as a "normal distribution" is symmetric about the mean and indicates that data that are close to the mean are more likely to occur than data that are far from the mean.

Given that:

μ= 1.4

σ=4.6

We know the formula of normal distribution is z = (x-μ)/σ

For [tex]P(x < 3)[/tex]

[tex]z=\frac{3-1.4}{4.6} \\z=0.35[/tex]

Answer:

Bonjour,

Step-by-step explanation:

y=k*(x-25)²+200

0=k*(55-25)²+200 => k=-2/9

y=-2/9(x-25)²+200

The a quadratic function that models the parabolic path of the object is y = -2/9(x-25)²+ 200.

For the given question;

The maximum height of the object which is launched from the top of a hill is 200 m.

The equation of the parabola is -

y=a*(x-h)²+k

(h,k) = vertex = (25, 200)

y = a*(x-25)²+200

Put (x,y) = (55,0)

0=a*(55 - 25)²+200

=> a = -2/9

Now put the value of 'a' and form the equation.

y = -2/9(x-25)²+ 200

Thus, the a quadratic function that models the parabolic path of the object is y = -2/9(x-25)²+ 200.

There are 7 pairs of whole numbers that have a sum of 12.

Given that we need to determine the pairs of whole numbers can you find that have a sum of 12.

To find the pairs of whole numbers that have a sum of 12, we can simply list all the possible combinations and count them.

Let's consider two whole numbers, x and y, such that x + y = 12. Since the numbers should be whole numbers and greater than or equal to 0, we have the following options:

x = 0, y = 12

x = 1, y = 11

x = 2, y = 10

x = 3, y = 9

x = 4, y = 8

x = 5, y = 7

x = 6, y = 6

So, there are 7 pairs of whole numbers that have a sum of 12.

These pairs are (0, 12), (1, 11), (2, 10), (3, 9), (4, 8), (5, 7), and (6, 6). Each of these pairs satisfies the condition that both x and y are whole numbers and their sum is equal to 12.

Note: We only consider x and y values up to 6 since beyond that, the sum would exceed 12, and we are only looking for pairs with a sum of 12.

The translation of the statement is 7x - 7 = 147 and the numerical value of x is 22.

Given the statement in the question?

"Seven subtracted from seven times a number is 147"

Translate the statement into an equation;

Let x represent the unknown number.

Now, combine

7x - 7 = 147

Therefore the translation of the statement is 7x - 7 = 147.

Next, we solve for x

7x - 7 = 147

Add 7 to both sides

7x - 7 + 7 = 147 + 7

7x = 154

x = 154/7

The equation to represent the growth of the trees is given by

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

Equation is defined as the quality of being equal and is frequently represented by a mathematical statement with equal values on either side or by a problem requiring consideration of a number of factors.

Given that tree A is 32 inches tall and tree B is 20 inches tall.

Tree A grows 6 inches per year.

Length of the tree A after t years = 32 + 6t

Tree B grows 9 inches per year

Length of the tree B after t years = 20 + 9t

Now let us consider that both trees grows equal after a certain period of time.

If we equate both the expressions then we can form an equation to calculate the value of t.

∴ 32+6t = 20+9t

or, 6t - 9t = 20 - 32
