so so that you could get both halves, we had to divide by two then I got 105 +105 meaning 210 could be divided by 2
Karen invested $2,000 in a special savings account.
The balance of this special savings account will double
every 5 years. Assuming that Karen makes no other
deposits and no withdrawals, what will be the balance
of Karen's investment at the end of 40 years?
A. $ 80,000
B. $ 256,000
C. $ 400,000
D. $ 512,000
E. $1,024,000
Answer:
D. $512,000
Step-by-step explanation:
Well if the balance doubles every 5 years, then dividing 40 by 5 gives us the number of times the money will double, which is 8. We can then turn this into the equation [tex]2000(2^{8})[/tex]. [tex]2^8[/tex] can be simplified to 256. Multiply that by 2000 and we get our answer, 512000. Hope this helps!

Step-by-step explanation:
Which of the following could be the ratio between the lengths of the two legs
of a 30-60-90 triangle?
Check all that apply.
O A. 1: 13
O B. 3: 315
O C. :
OD. 1: 12
O E. : 13
O F. 13:3
Answer:
Step-by-step explanation:
we know that
In a triangle
the ratio between the lengths of the two legs is equal to the tangent
so
therefore
the answer is
Option B
-------> could be the ratio
because is the value of the
Option C
------> could be the ratio
because is the value of the
Option E
-------> could be the ratio
because is the value of the
The options B, C and E giving the ratios are correct.
What are ratios?Ratio, in math, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Given that, a 30-60-90 right triangle, we need to find the ratio between the lengths of the two legs of the triangle,
Since, we know that,
In a right triangle, the ratio between the lengths of the two legs is equal to the tangent.
so,
Tan 30° = 1/√3
Also,
√3 / 3 = 1/√3
3/3√3 = 1/√3
Hence, the options B, C and E giving the ratios are correct.

The New York Times and CBS News conducted a nationwide poll of 1048 randomly selected 13- to 17-year-olds. We can consider the sample to be a SRS.
a. Of these 1048 teenagers, 692 had a television in their room. Give a 95% confidence interval for the proportion of all people in this age group who had a TV in their room at the time of the poll
b. Of the 1048 teens surveyed, 189 named Fox as their favorite television network. Give a 90% confidence interval for the proportion of all people in this age group who would choose Fox as their favorite network.
c. Suppose you were to change the confidence level in (b) to 95% using the same sample. How would the confidence interval change? No calculations necessary.
a. The confidence interval would be the same width but shifted to the left
b. The confidence interval would be the same width but shifted to the right
c. The confidence interval would have the same center but be wider
d. The confidence interval would have the same center but be narrower

I need some help with my grade 10 math work
A music store had a sale on tapes and CDs. Tapes were on sale for $5 each and CDs were on sale for $7. During the sale, 32 tapes and CDs were sold. The cash receipts from the sale of the tapes and CDs, before taxes, were $200. Let x represent the number of tapes and let y represent the number of CDs sold during the sale.
Answer:
12 tapes and 20 CDs were sold.
Step-by-step explanation:
Since a music store had a sale on tapes and CDs, and tapes were on sale for $ 5 each and CDs were on sale for $ 7, and during the sale, 32 tapes and CDs were sold, and the cash receipts from the sale of the tapes and CDs, before taxes, were $ 200, to determine the number of CDs and tapes sold during the sale, the following calculation must be performed:
7 - 5 = 2
32 x 5 = 160
200 - 160 = 40
40/2 = 20
32 - 20 = 12
12 x 5 + 20 x 7 = X
60 + 140 = X
200 = X
Therefore, 12 tapes and 20 CDs were sold.

Select the function that is nonlinear.
a
y = 3x - 4
b
y = 2x3 - 10
c
y = 4x -12
d
y = x + 101
Answer:
B
Step-by-step explanation:
A C and D are all linear. The powers on x in all three questions is 1. For example the first answer could be written as y = 3x^1 - 4. C and D are much the same.
So if you are thinking that B must be the answer, you would be right. x is raised to the third power -- or I think that is what is intended. y = x^3 - 10
Please explain how you got the answer!

Jeremy has a stand in the farmer's market where he sells strawberries by the pound. The table shows the weights of the strawberries and the prices per quantity. The relationship between the amount of strawberries in pounds and the price is a proportional relationship.
Which statement is true?
A.)The table does not represent a proportional relationship because the differences between consecutive terms in each column do not have the same ratio.
B.)The table does not represent a proportional relationship because the ratio between the price column and the weight column is not the same for each row.
C.)The table represents a proportional relationship because the differences between consecutive terms in each column have the same ratio.
D.)The table represents a proportional relationship because the ratio between the price column and the weight column is the same for each row.

The giant outlier is Palm Beach county. We can see that it lies well beyond the range of votes this regression model would predict for Buchanan, based on the observed linear trend between total votes and votes for Buchanan across all the other counties. Calculate the residual for Palm Beach county to determine just how much larger Buchanan's vote total was compared to what we'd predict based on the election results from the other counties.
Answer:
Hello your has some missing information attached below is the missing information
answer : 2355.62
Step-by-step explanation:
Calculating the residual for Palm Beach county
Given that total votes = 430772
and The regression equation = 56.115131 + 0.0023197 * Total Votes
The predicted Buchanan = 56.115131 + 0.0023197 * 430772 = 1055.377
while the Actual Votes Buchannan = 3411
Residual for Palm Beach county = Actual votes Buchannan - Predicted
= 3411 - 1055.377 = 2355.62
