Hey,

235,500,000,000,000 in scientific notation is 2.355 × 10^14.

Here are the steps to converting a number to scientific notation:

1. Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

2. Count how many places you moved the decimal point. This number is b. If you moved the decimal to the left b is positive. If you moved the decimal to the right b is negative. If you did not need to move the decimal b = 0.

3. Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

4. Remove trailing 0's only if they were originally to the left of the decimal point.

Cheers,
Izzy

Answer:

a ≈ 4.68

Step-by-step explanation:

The law of cosines tells you ...

a² = b² +c² -2bc·cos(A)

a = √(b² +c² -2bc·cos(A))

a = √(5² +8² -2·5·8·cos(33°)) = √(25 +64 -80·0.83867) ≈ √21.906

a ≈ 4.68

Tickets for a concert cost $10 each if you order them online, but you must pay a service charge of $8 per order. The tickets are

jekas [21]

Answer:

The system of equation to model the situation are:

C = 10t + 8

C = 12t

Step-by-step explanation: Complete question ( Let C be the total cost and let t be the number of tickets).

Ordering tickets online cost $10 plus additional service charge of $8.

Therefore total cost,C = 10t + 8

Buying tickets at the door cost $12

Therefore, total cost,C = 12t

The system of equation to model the situation are:

C = 10t + 8

C = 12t

In order for you to use the goodnees-of-fit test, the test of independence, or the test of homogeneity, the expected frequencies

nataly862011 [7]

The condition for the expected value in the goodness of fit test is that the expected frequency is at least 5.

According to the statement

we have to find the condition of the expected values in the case of testing of goodness-of-fit test.

So, For this purpose we know that the

The goodness of fit test is of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between observed values and the values expected.

So, The main condition of the expected value for the goodness of fit test is

For each category, the expected frequency is at least 5.

Without this condition the test is not possible, so overall this the main condition related the goodness of fit test.

So, The condition for the expected value in the goodness of fit test is that the expected frequency is at least 5.

4x - 7 (2 - x) = 3x + 2

juin [17]

Answer:

x=2

Step-by-step explanation:

4x−7(2−x)=3x+2

4x+(−7)(2)+(−7)(−x)=3x+2(Distribute)

4x+−14+7x=3x+2

(4x+7x)+(−14)=3x+2(Combine Like Terms)

11x+−14=3x+2

11x−14=3x+2

Step 2: Subtract 3x from both sides.

11x−14−3x=3x+2−3x

8x−14=2

Step 3: Add 14 to both sides.

8x−14+14=2+14

8x=16

Step 4: Divide both sides by 8.

x=2

frozen [14]

Answer:

option (2) it is and isosceles triangle.

Step-by-step explanation:

In circle L, points E and F lie on the circle such that E, F and L are not collinear

If LE, LF and EF are drawn

So, LE = EF = the radius of the circle L

So, LEF is an isosceles triangle.

The answer is option (2) it is and isosceles triangle.
