what is 4(11h +3g)?????

Answers

Answer:

[tex]12g+44h[/tex]

Step-by-step explanation:

Step 1: Rearrange terms

[tex]4(11h+3g)\to4(3g+11h)[/tex]

Step 2: Distribute

[tex]4(3g+11h)\to12g+44h[/tex]

Answer:

44h+12g

Step-by-step explanation:

Okay, so, this a standard algebraic expanding problem, so:

We take our 4(11h + 3g)

because we have parenthesis, we have to distribute the 4:

4 x 11h + 4 x 3g = 44h + 12g

So, 4(11h + 3g) expanded is 44h + 12g

A sporting goods store sells two types of snowboards. Brand S sells for $309. Brand B sells for $489. Last month, the store sold 11 snowboards for $4299. How many of each type of snowboard were sold?
Define each variable.
Set up the system of equations for the situation.
Solve the system using the substitution method. Be sure to express your final answer with the correct units.

Answers

Let S be the number of Brand S snowboards sold.
Let B be the number of Brand B snowboards sold.

309S + 489B = 4299
S + B = 11

S = 6 snowboards sold
B = 5 snowboards sold

In March, an American tourist changed US $1000 into Jamaican currency. Calculate the amount of JM dollars he received. USD $1.00 = JMD $146
a. $0.146
b. $146,000
c. 104,600
d. 150,000

Answers

Answer:

b. $146,000

Step-by-step explanation:

1 usd = 146 jmd

1000 = ___ jmd

We multiply 1000 and 146:

1000($146) = $146,000

1000$ X 146$ = 146,000$ you take the amount in the US dollar that they want you to calculate and multiply it to the JMD $146

find the angle sum of polygon which had 9 sides

Answers

Answer:

1260°

Step-by-step explanation:

Number of sides was given as 9, hence ( n= 9)

Sum of interior angle of a polygon can be determined using the expression below

[(2n-4)90°]

Substitute n=9

[((2×9) -4)) ×90]

= [(18-4)×90]

(14×90)=1260°

Hence, angle sum of polygon which had 9 sides is 1260°

Answers

Answer:

Step-by-step explanation:

Yes, the median is 49.5, Q1 is 41, Q3 is 52 (I always have to check)

So the box should start at Q1, end at Q3, and have it's middle line on the median. For this data set, box should start on 41, end on 52, and have its inner line on 49.5.

Of your choices, that's option C.

At the 95% confidence level, the margin of error for this survey, expressed as a proportion, is approximately 0.0288.

To calculate the margin of error for a survey expressed as a proportion, we need to use the formula:

Margin of Error = Critical Value [tex]\times[/tex] Standard Error

First, let's find the critical value.

For a 95% confidence level, we can refer to the standard normal distribution (Z-distribution) and find the z-value associated with a 95% confidence level.

The critical value for a 95% confidence level is approximately 1.96.

Next, we need to calculate the standard error.

The standard error for a proportion can be computed using the formula:

Standard Error [tex]= \sqrt{((p \times (1 - p)) / n)}[/tex]

Where:

p = proportion of respondents in favor of the plan

n = sample size

In this case, the proportion in favor of the plan is 37/185 = 0.2 (rounded to the nearest thousandth).

The sample size is 185.

Now we can calculate the standard error:

Standard Error [tex]= \sqrt{((0.2 \times (1 - 0.2)) / 185)}[/tex]

Simplifying further:

Standard Error ≈ [tex]\sqrt{((0.04) / 185)}[/tex]

Standard Error ≈ [tex]\sqrt{(0.0002162)}[/tex]

Standard Error ≈ 0.0147 (rounded to the nearest thousandth)

Finally, we can calculate the margin of error:

Margin of Error = 1.96 [tex]\times[/tex] 0.0147

Margin of Error ≈ 0.0288 (rounded to the nearest thousandth)
