Answer:

B

Step-by-step explanation:

The interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

The interval estimate of the population mean can be found out using the following formula:

[tex]\overline X\pm MOE[/tex]

Here, [tex]\overline X[/tex] is the average mean, and the MOE is the margin of error.

On a highway, a random sample is taken of the speed, in mph, of 50 cars.

Put the values in the above formula as,

[tex]61.8\pm 2.3\\59.5,641[/tex]

Thus, the interval estimate of the population mean

[tex]59.5 < h < 61.8[/tex]

Hence, the interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.

Is the answer. I know because I took the test.

Answer:

$1,061.21

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Present value (PV) = $1,000

Rate of interest compounded yearly (r) = 2%

Time period (n) = 3

So, we can calculate the future value (FV) by using following formula,

Future Value = PV(1 + r)^n

By putting the value, we get

FV = $1,000 ( 1 + 0.02)^3

= $1,000 ( 1.02)^3

= $1,000 ( 1.061208)

= $1,061.21

Answer:

Let us consider a binomial expression

For example,

x²+(a+b)x+ab

x²+ax+bx+ab

x(x+a)+b(x+a)

(x+a)(x+b)

Therefore, the above binomial expression has two factors (x+a) and (x+b).

Now by numericals

Consider, x²+12x+35

[tex] {x}^{2} + 12x + 35\\Factors\:of\: 35\: is\: 5\: and\:7 \\ {x}^{2} + 5x + 7x + 35 \\ x(x + 5) +7(x + 5) \\ (x + 5)(x + 7)[/tex]

Here, (x+5) and (x+7) are the factors of the binomial expression x²+12x+35.

Answer:

Binomials are two-term expressions connected with a plus sign or minus sign, such as {ax+b}ax+b. The first term will always include a variable, while the second term may or may not. 1st: factoring is when you break a large number down into it's simplest divisible parts. Each one of these parts is called a "factor." So, for example, the number 6 can be evenly divided by four different numbers. 2nd:  A binomial is simply the addition or subtraction of two numbers, at least one of which contains a variable. Sometimes these variables have exponents, like x^5 or 5y^6. 3rd :When first factoring binomials, it can help to reorder equations with ascending variable terms. This means you find the highest possible number that both parts of the binomial are divisible by. If you're struggling, simply factor both numbers on their own, then see what the highest matching number is.

Answer: 2-cup bowl

Step-by-step explanation:

Given: Sam has 2-cup bowl, a 4-cup bowl, and a 6-cup bowl.

here, Quantity in 2-cup <  Quantity in 4-cup <  Quantity in 6-cup .

So,  2-cup bowl is the smallest bowl with the least capacity.

So, if Sam is interested to make the punch in the smallest bowl, then she will absolutely take  2-cup bowl.

Hence, the smallest bowl Sam can use to make the punch =2-cup bowl

Answer:

Option E : n+70 is the correct answer.

Step-by-step explanation:

Given that:

n is divisible by 2,5 and 14.

We have to add a number to n which will make the resulting number also a divisible of 2, 5 and 14.

Therefore,

We will add a number that is multiple of 2,5 and 14

Here,

7 is not a multiple of 2,5 and 14.

20 and 10 are multiples of 2 and 5 but not 14.

70 is a multiple of 2,5 and 14.

14 is a multiple of 2 and 14 but not 5.

Hence,

Option E : n+70 is the correct answer.

Step-by-step explanation:

[tex] {c}^{2} = {a}^{2} + {b}^{2} \\ {c}^{2} = {15}^{2} + {15}^{2} \\ {c}^{2} = 450 \\ c = \sqrt{450} = \sqrt{ {15}^{2} \times 2 } = 15 \sqrt{2} [/tex]

The percentage error in the acceleration is 11.3%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The actual acceleration of the object is 9.80 meters per second.

The acceleration of an object is 10.91 meters per second.

Now,

Percentage error.

= (Experiment acceleration - Actual acceleration) / Actual acceleration x 100

= (10.91 - 9.80) / 9.80 x 100

= 1.11 / 9.80 x 100

= 11.33 %

Thus,

The percentage error is 11.3%.
