PLEASE HELP ME!! what is the answer?

The required sum is 2 + (−4) + (−10) + (−16) + (−22)

From the given sum of a sequence, we are to find the sum of the given sequence from n = 0 to n = 4

When n = 0

a(0) = 2 - 6(0)

a(0) = 2 - 0
a(0) = 2

When n = 1

a(1) = 2 - 6(1)

a(1) = 2 -6
a(1) = -4

When n = 2

a(2) = 2 - 6(2)

a(2) = 2 - 12
a(2) = -10

When n = 3

a(3) = 2 - 6(3)

a(3) = 2 - 18
a(3) = -16

When n = 4

a(4) = 2 - 6(4)

a(4) = 2 - 24
a(4) = -22
Hence the required sum is 2 + (−4) + (−10) + (−16) + (−22)

Step-by-step explanation: source: trust me bro

Answer:

  69.15%

Step-by-step explanation:

You want the probability of a race time being less than 348 minutes if times are normally distributed with mean 319 minutes, and standard deviation 58 minutes.

The probability is found using the suggested resources. It will be ...

  P(X<348) ≈ 0.6915

As a percentage, that is ...

  0.6915 × 100% = 69.15%

The percentage of times shorter than 348 minutes is about 69.15%.

__

Additional comment

The corresponding Z-score is (348-319)/58 = 0.500. Your table should give you the above value directly for that Z-score. No interpolation will be necessary.

Thus the last option is the correct answer.

Answer:

The answer is 1/2a + 20

Step-by-step explanation:

Now, Substitute value of b

1/2a + 2/3b

1/2a + 2/3(30)

1/2a + 2 × 10

1/2a + 20 = a/2 + 20 = (a + 40) ÷ 2

Step-by-step explanation:

The monthly loan payment should be $168.75.

Since Ally is buying a speed boat for $10,000 with a down payment of $2,500. The bank approved a simple interest flat rate loan for 5 years at 7% APR.

The net principal should be

= $10,000 - $2,500

= $7,500

Now simple interest should be

= $7,500(5)(7%)

= $2,625

Now the total amount should be

= $7,500 + $2,625

= $10,125

Now the monthly payment is

[tex]= 10125\div (12\times 5)\\\\= 10125 \div 60[/tex]

= $168.75

Therefore, The monthly loan payment should be $168.75.

Answer:

x=7

y=-17

Step-by-step explanation:

Lets do 10x-7. Basically it will be equal to 63, so the equation will be 10x-7=63

to find x we need to add 63+7=70 and put 10x with an equal sign which is 70=10x

7=x because 70/10=7.

in a simple way it is

10x-7=63

10x=7+63=70

10x=70

x=7

Lets do -5y+3. It is equal to 88.

so it will be

-5y+3=88

-5y=88-3=85

-5y=85

y=-17

Answer:

[tex]\Longrightarrow: \boxed{\sf{x=7, \ y=-17}}[/tex]

Step-by-step explanation:

To find the value of x and y in the parallelogram, you have to isolate it on one side of the equation.

First, add by 7 from both sides.

10x-7+7=63+7

Solve.

Add the numbers from left to right.

63+7=70

10x=70

Then, you divide by 10 from both sides.

10x/10=70/10

Solve.

Divide these numbers goes from left to right.

70/10=7

[tex]\Longrightarrow: \boxed{\sf{x=7}}[/tex]

Subtract by 3 from both sides.

-5y+3-3=88-3

Solve.

Subtract the numbers from left to right.

88-3=85

-5y=85

Divide by -5 from both sides.

-5y/-5=85/-5

Solve.

Divide the numbers from left to right.

85/-5=-17

[tex]\Longrightarrow: \boxed{\sf{y=-17}}[/tex]

Answer:

Step-by-step explanation: . Paid to the painter for 12 hrs=Rs.360........therefore,......amt paid for 1 hr=360/12=30......... Therefore,.....amt paid for 9 hrs=9*30=Rs.270........hope i helped u:)

The amount paid for 9 hours is R270

The expression can be represented by using the following ratio

Ratio = Amount : Time

So, we have:

R360 : 12 = Amount : 9

Express as fraction

R360 / 12 = Amount / 9

Multiply both sides by 9

Amount = R360 / 12 * 9

Evaluate the product

Amount = R270

Hence, the amount paid for 9 hours is R270

Answer:

A.

Step-by-step explanation:

Organize the terms and you have this:

(-3x^2+x^2)+(4x-3x)+(-8-2)

The equal terms, i.e the terms with the same exponent (the ones that are in parentheses) are reduce:

(-3x^2+x^2)=-2x^2

(4x-3x)=x

(-8-2)=-10

Then

-2x^2+x-10

The number of different seating arrangements is an illustration of permutation

There are 151200 different seating arrangements

The number of seats (n) is given as:

n = 10

The number of people (r) is given as:

r = 6

So, the number of seating arrangements is:

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

This gives

[tex]^{10}P_6 = \frac{10!}{(10 - 6)!}[/tex]

Simplify

[tex]^{10}P_6 = \frac{10!}{4!}[/tex]

Evaluate the quotient

[tex]^{10}P_6 = 151200[/tex]

Hence, there are 151200 different seating arrangements
