Answer:

5 : 6 and 20 : 24

Step-by-step explanation:

Given the ratio

10 : 12 ( divide both parts by 2 )

= 5 : 6

and

10 : 12 ( multiply both parts by 2 )

= 20 : 24

To create equivalent ratios we can divide or multiply the parts by the same value.

The value of the function y= (3/5)t decrease by what percentage of t increases by 1 unit

kirza4 [7]

Answer:

Percent of decrease in the value is 40%.

Step-by-step explanation:

Let's find the value of y when t=1 and t=2 because need to find the decrease by percent of t increases by 1 unit.

When t=1

y= $\frac{3}{5}^{1}$ =0.6

When t=2

y= $\frac{3}{5} ^{2}$ =0.36

Percent of decrease = 100 % - $\frac{0.36}{0.6}*100%$ % = 100% -60% =40%

Callie and Madison went to buy concert tickets for themselves and their five friends. The

nika2105 [10]

Answer:

They bought 0 ticket of closest section and 7 tickets of other section

Step-by-step explanation:

- Callie and Madison went to buy concert tickets for themselves and

their five friends

- That mean they are 7

- Tickets for the closest section were $45 each

- Tickets for other section were $30 each

- They ended up spending a total of $210

- Assume that they buy x tickets for closest section and y tickets for

the other section

∵ They want 7 tickets

∴ x + y = 7 ⇒ (1)

∵ The cost of the closest section ticket was $45

∵ The cost of the other section ticket was $30

∵ They spent $210 on them

∴ 45x + 30y = 210

- All terms have common factor 15, then divide them by 15

∴ 3x + 2y = 14 ⇒ (2)

* Now we have a system of equations to solve

- Multiply equation (1) by -2 to eliminate y

∴ -2x - 2y = -14 ⇒ (3)

- Add equations (2) and (3)

∴ x = 0

- substitute the value of x in equation (1) to find y

∴ 0 + y = 7

∴ y = 7

∵ x represents the number of tickets of the closest section and y

represents the number of tickets in the other section

∴ They bought 0 ticket of closest section and 7 tickets of other

section

a taste test asks people from Texas and California which pasta they prefer, brand A or brand B. this table shows the results

ELEN [110]

Answer:

Step-by-step explanation:

Two events A and B are independent when

$P(A|B)=P(A),$

where $P(A|B)$ is the probability that event A occurs given that event B has occured.

A = randomly selected person is from California

B = randomly selected person preferred brand A

A|B = being a person from California and preferring brand A.

Hence,

$P(A)=\dfrac{150}{275}=\dfrac{6}{11}\approx 0.55\\ \\P(B)=\dfrac{176}{275}=\dfrac{16}{25}=0.64\\ \\P(A|B)=\dfrac{96}{176}=\dfrac{6}{11}\approx 0.55$

Since $P(A)=P(A|B),$ events are independent.
