Figure ABCDEFG is shown. A is at negative 3, negative 2. B is at negative 3, 0. C is at negative 1, 1. D is at 3, 1. E is at 3,
Answer/Step-by-step explanation:
Two figures can only be similar if their corresponding lengths are proportional to each other, that is the ratio of their corresponding sides are equal.
AB corresponds to HI.
AB = 2 units, HI = 1 units.
AB : HI = 2/1 = 2
The ratio of all the sides of ABCDEFG are equal to the corresponding sides of HIJKLMN, which is 2, EXCEPT for side FG which corresponds to MN.
FG = 1 units
MN = 1 units.
FG : MN = 1/1 = 1
This ratio is different from what we have for the ratio of the other corresponding sides of both figures.
Therefore, the figures are not similar.

Denmark uses the kroner as its currency. Before a trip to Denmark, Mia wants to exchange $1,700 for kroner.
A. Does bank A or Bank B have the better exchange rate? Explain.
B. How many more kroner would Mia get if she exchanged her $1,700 at the bank with the better exchange rate?
Answer:
a. Bank A
b. 8,670 Kroner
Step-by-step explanation:
a. The bank that will give Mia a better exchange rate is the Bank who's exchange rate is higher in value, that is has more units of Kroner per $1.
Let's find which Bank has the best exchange rate.
Using the pair, (100, 510),
Bank A exchange rate = [tex] \frac{510}{100} = 5.1 [/tex]
Bank A exchange rate is 5.1 kroner per dollar
Using the point, (10, 50) on the graph,
Bank B exchange rate = [tex] \frac{50}{10} = 5 [/tex]
Bank B exchange rate is 5.0 kroner per dollar.
✅Therefore, Bank A has a better exchange rate.
Mia will get more Kroner per each dollar she wants to exchange if she lots for Bank A.
b. If Mia exchanged her $1,700 at Bank A, she would get:
1,700 × 5.1 = 8,670 Kroner.
a) The bank A have the best exchange rate.
b) Mia will receive an addition of 1303,90 crowns with the better exchange rate.
a) Given the existence of linear relationship between the amount of dollars ([tex]x[/tex]) and the expected amount of crowns ([tex]y[/tex]), the exchange rate ([tex]r[/tex]) is represented by the slope of each line, which is determined by definition of secant line. The greater the slope, the better the exchange rate.
Now we proceed the exchange rate for each bank:
Bank A
[tex]r_{A} = \frac{612-408}{120 - 80}[/tex]
[tex]r_{A} = 5.1\,\frac{DKC}{USD}[/tex]
Bank B
[tex]r_{B} = \frac{130 - 0}{30 - 0}[/tex]
[tex]r_{B} = 4.333\,\frac{DKC}{USD}[/tex]
The bank A have the best exchange rate.
b) The addition ([tex]\Delta y[/tex]), in crowns, is defined by the following formula:
[tex]\Delta y = (r_{A}-r_{B})\cdot x[/tex] (1)
If we know that [tex]r_{A} = 5.1\,\frac{DKC}{USD}[/tex], [tex]r_{B} = 4.333\,\frac{DKC}{USD}[/tex] and [tex]x = 1700\,USD[/tex], then the addition is:
[tex]\Delta y = (5.1-4.333)\cdot 1700[/tex]
[tex]\Delta y = 1303,90\,DKC[/tex]
Mia will receive an addition of 1303,90 crowns with the better exchange rate.

Yavonee reads $14$ pages in $28$ minutes.
At this rate, how many pages does she read in $50$ minutes?
Answer:
25 pages in 50 minutes
Step-by-step explanation:
As 14 pages = 28 mins
For 1 page = 2 mins
For x pages = 50 mins
So 50/2 = 25
So 25 pages for 50 mins

1. The probability of telesales representative making a sale on a customer call is 0.15.
Find the probability that
(a) no sales are made in 10 calls
B)more than 1 sales are made in 20calls
Answer:
a) the probability that no sales are made in 10 calls is 0.1969
b) the probability more than 1 sales are made in 20calls is 0.8244
Step-by-step explanation:
Given that;
p = 0.15
q = 1 - p = 1 - 0.15 = 0.85
a) probability that no sales are made in 10 calls will be;
n = 10
p(x=0) = ¹⁰C₀(0.15)⁰ (0.85)¹⁰ = 0.1969
Therefore the probability that no sales are made in 10 calls is 0.1969
b) probability more than 1 sales are made in 20calls
n = 20
let y be number of sales in 20 calls
y∪Bin(n=20, p=0.15)
p(y > 1) = 1 - [p(y=0) + p(y=1)
= 1 - [²⁰C₀(0.15)⁰ (0.85)²⁰ + ²⁰C₁(0.15) (0.85)¹⁹] = 0.8244
Therefore the probability more than 1 sales are made in 20calls is 0.8244

Do you take the free samples offered in super- markets? About 70% of all customers will take free samples. Furthermore, of those who take the free samples, about 30% will buy what they have sampled. Suppose you set up a counter in a supermarket offering free samples of a new product. The day you are offering free samples, 317 customers pass by your counter.
Answer:
222 customers took a free sample of the product, and 67 finally bought it.
Step-by-step explanation:
Given that 317 consumers passed through the sample stand, and taking into account that 70% usually take free samples, the number of people who take free samples is determined by the following calculation:
317 x 70/100 = X
22,190 / 100 = X
221.9 = X
Therefore, of the 317 consumers, about 222 took free samples of the product. Furthermore, of those 222, it is estimated that 30% bought the product after testing the sample. To determine the number of people who bought the product, the following calculation must be made:
222 x 30/100 = X
6,660 / 100 = X
66.6 = X
Therefore, 67 consumers purchased the product after taking a free sample of it.

The lowest elevation in Long Beach, California, is 7 1/4 feet below sea level. The elevation of Death Valley is about 40 1/2 times lower than the elevation of Long Beach. What is the approximate
elevation of Death Valley?
Answer:
the approximate elevation of Death Valley is -287 feet below sea level
Step-by-step explanation:
if we are talking about the lowest elevation, it would be -7
if Death Valley is 40 times lower than the lowest elevation of Long Beach
u would multiply the 2
so 40x7=280
then you subtract from -7
-7-280=-287
the approximate elevation of Death Valley is -287 feet below sea level
