Answer:

60.6

Step-by-step explanation:

The formula for finding the circumference of a circle is C = 2πr

C is circumference, π is pi (we'll just us 3.14 here), and r is radius.

The radius is found by dividing the diameter in half.

19.3/2=9.65

So the equation should look like this:

C = 2(3.14)(9.65)

C = 60.602

C = 60.6

Answer:

C.

D.

E.

Step-by-step explanation:

The two options that yield the same value for 'x' as the equation 'Three-fifths (30 x minus 15) = 72' are '3 (6 x minus 3) = 72' and 'x = 4.5'. The confusion can be eliminated by simply breaking down and solving the initial equation for 'x', and then substituting the calculated value for 'x' into the optional equations.

To discover which options yield the same value as 'Three-fifths (30 x minus 15) = 72', we first need to solve the given equation for 'x'. This can be done as follows:

Substitute x = 4.5 into each option:

Therefore, '3 (6 x minus 3) = 72' and 'x = 4.5' provide the same value for x as the initial equation 'Three-fifths (30 x minus 15) = 72'.

Answer:

Step-by-step explanation:

The total number of paint used = 8.8pints

If 4/5 of this amount is white paint, then the amount of white pint is expressed as;

[tex]= \frac{4}{5}*8.8\\= \frac{35.2}{5}\\[/tex]

= 7.04

This means the amount of white paint used is 7.04pints.

amount of blue paint used = Total amount of paint - amount of white paint

amount of blue white paint used = 8.8 - 7.04

amount of blue paint used = 1.76pints of paint

Answer:

[tex]P(H|P) = \frac{P(H \cap P)}{P(P)}[/tex]

And replacing we got:

[tex] P(H|P) =\frac{0.28}{0.64}= 0.4375[/tex]

And the probability required for this case is 0.4375

Step-by-step explanation:

For this case we define the following events:

H = represent that the student is honorable

P= represent that the student have a part time job

And we have the following probabilities:

[tex] P(H) = 0.42 , P(P) = 0.64, P(H \cap P) =0.28[/tex]

And we want to find this probability:

[tex] P(H|P)[/tex]

And we can use the following probability:

[tex]P(H|P) = \frac{P(H \cap P)}{P(P)}[/tex]

And replacing we got:

[tex] P(H|P) =\frac{0.28}{0.64}= 0.4375[/tex]

Step-by-step explanation:

the pattern here is dividing by -5, so just continue dividing by -5 starting on -3 and continuing 4 more times. record each number and then add them together using a calculator. you will get -62.5008

Please mark brainliest :)

Answer:

-62.5008

Step-by-step explanation:

Find the pattern first: -75/15 = -5

Find the first 7 terms: -3/-5, 3/25, -3/125, 3/625

Add: -62.5008

Answer:

  -62.5008

Step-by-step explanation:

The terms form a geometric sequence with first term -75 and common ratio -1/5. The sum of n terms of such a sequence is...

  Sn = a1(1 -r^n)/(1 -r)

For the values of a1, r, and n, this sum is ...

  S7 = -75(1 -(-1/5)^7)/(1 -(-1/5)) = -75(1 +1/78125)/(1 +1/5)

  = -75(13021/15625) = -62 313/625

  = -62.5008

The sum of the first 7 terms of the sequence is -62.5008.

To simplify the expression 5.2 + 3.6x - 8 + x, combine like terms to get -2.8 + 4.6x, which is the final simplified expression.

The student's question involves simplifying the expression 5.2 + 3.6x – 8 + x. To simplify the given algebraic expression, combine like terms. Like terms in this expression are the constant terms (5.2 and -8) and the variable terms (3.6x and x).

First, add the constant terms together:

5.2 - 8 = -2.8

Then, combine the variable terms:

3.6x + x = (3.6 + 1)x = 4.6x

Now, put the constants and variable terms together to get the simplified expression:

-2.8 + 4.6x

To check if the simplified expression is reasonable, ensure that all like terms have been correctly combined. There is no further simplification possible, so this is the final answer.

To multiply powers with the same base, like (4^6)(4^-8), add the exponents to get 4^(6-8) = 4^-2. Converting the negative exponents gives us 1/4^2 or 1/16 as the simplified expression.

To rewrite the expression in the form 4n4n, we use the rule that when multiplying two numbers with the same base, we add their exponents. So, (46)(4-8) = 4(6 + (-8)) = 4-2 = 1/42 = 1/16.

When multiplying powers with the same base, you simply add the exponents. In the expression (4^{6})(4^{-8}), we add the exponents 6 and -8. The rules of exponents tell us that 4^{6} \times 4^{-8} = 4^{6-8} = 4^{-2}. Negative exponents indicate the reciprocal of the base raised to the positive of that exponent. Therefore, 4^{-2} = \frac{1}{4^{2}} = \frac{1}{16}. This simplified expression demonstrates how to work with exponents and manage negative exponents effectively.

Answer:

7.68 s

Step-by-step explanation:

The vertical motion formula is:

[tex] h_{t} = h_{0} + v_{0}t - \frac{gt^{2}}{2} [/tex]

Where:

h(t): is the final height = 0

h(0): is the height of the cliff = 104 foot

v(0): is the initial velocity = 110 ft/s

g: is the gravity = 9.8 m/s² = 32.15 ft/s²

Hence, from the vertical motion formula we can find the time that will take the rocket to hit the ground:

[tex] 0 = 104 + 110*t - \frac{32.15t^{2}}{2} [/tex]

[tex] 0 = 104 + t(110 - 16.08t) [/tex]

We have two solutions:

t₁= -0.84 s

t₂ = 7.68 s

We will take the positive value, thus the time that will take the rocket to hit the ground is 7.68 s.

Answer:

The nth term can be represented by;

Tn = 5n- 1

Step-by-step explanation:

In this question, we are concerned with finding an expression in terms of n for then the term of the sequence.

Mathematically, the nth term of a sequence Tn can be represented by the formula;

Tn = a + (n-1)d

where a is the first term in the sequence which is 4 , and d is the common difference which is the difference between 2 consecutive terms which is 9-4= 5

our n is n, since we do not know the number of terms we are finding for

Plugging these values, we have;

Tn = 4 + (n-1)5

Tn = 4 + 5n -5

Tn = 5n- 1

Step-by-step explanation:

The linear correlation coefficient r is **1.2237445080439002**.

To calculate the linear correlation coefficient r, we can use the following formula:

[tex]r = (\sum(x - \bar x)(y - \bar y)) / \sqrt(\sum(x - \bar x)^2 \sum(y - \bar y)^2)[/tex]

where:

* [tex]\sum[/tex] is the sum of the values

* [tex]\bar x[/tex] is the mean of x

* [tex]\bar y[/tex] is the mean of y

First, we need to calculate the mean of x and y:

[tex]\bar x[/tex] = (4 + 53 + 86 + 162) / 4 = 71.25

[tex]\bar y[/tex] = (-5 - 1 + 13 + 16) / 4 = 5.75

Next, we need to calculate the sum of the squared deviations from the mean for x and y:

[tex]\sum(x - \bar x)^2 = (47.25^2 + 17.25^2 + 14.25^2 + 90.75^2) = 10148.5[/tex]

[tex]\sum(y - \bar y)^2 = (11.25^2 + 6.75^2 + 7.25^2 + 10.25^2) = 317.5[/tex]

Now, we can calculate the linear correlation coefficient r:

[tex]r = (\sum(x - \bar x)(y - \bar y)) / \sqrt(\sum(x - \bar x)^2 \sum(y - \bar y)^2)[/tex]

r = (47.25 * 11.25 + 17.25 * 6.75 + 14.25 * 7.25 + 90.75 * 10.25) / √(10148.5 * 317.5)

r = 1.2237445080439002

Therefore, the linear correlation coefficient r is **1.2237445080439002**.

This value indicates a strong positive correlation between x and y.
