Answer 1
Answer:

Answer: A. Both expressions are equivalent to 35 when t=2.


Step-by-step explanation:

Given: Gianna is substituting t = 2 and t = 7 to determine if the two expressions are equivalent.

At t=2

5(2t+3)=5(2(2)+3)=5(4+3)=5(7)=35

5t+25=5(2)+25=10+25=35

Therefore, both expressions are equivalent to 35 when t=2.

At t=7

5(2t+3)=5(2(7)+3)=5(14+3)=5(17)=85

5t+25=5(7)+25=35+25=60

Hence, A is the write option.

Two of my digits are even, my last digit is odd, the sum of my digits is 11. I'm between 256 and 299, and I'm not 281. What am I?

Answers

ok so
2 digits even, last is odd
sum is 11
between 256 and 299
not 281

ok so we take 3 facts
sum is 11
between 256 and 299
2 are even

between 256 and 299, the first number is always 2
therefor
2+x+y=11
x+y=9
the other 2 numbers add up to 9
write all 2 ditgit numbers between 56 and 99 that add up to 9
63,72,81,90
not 281 so get rid of 81
and last diti is odd and first 2 are even so get rid of 72 and 90
therfor is it 63

263
You are 263. 

Two of the digits are even. 2 and 6.

Last digit is odd. 3 is odd.

Sum of digits is 11.    2 + 6 + 3 = 11.

And 263 is between 256 and 299.

If you roll two number cubes, what is the probability of their sum being seven or higher?

Answers

1) Number of possible outcomes when 2 cubes are rolled = n^2 = 6^2 = 36
Possible outcomes for a sum = 7 are 6 as detailed below
(1,6) (2,5) (3,4) (4,3) (5,2) (6,1) = 6
Possible outcomes for a sum = 11 are 2 as detailed below
(5,6) (6,5) = 2
Required probability = 6/36 + 2/36 = 8/36 = 0.22222

2) Number of possible outcomes when a cube and a coin are tossed = m*n = 6*2 = 12
Possible outcomes for a tail and 6 = 1
Required probability = 1/12 = 0.08333

3) Possible outcomes for a sum =3 are 2 as detailed below
(1,2) (2,1) = 2
Possible outcomes for a sum = 8 are 5 as detailed below
(2,6) (3,5) (4,4) (5,3) (6,2) = 5
Required probability = 2/36 + 5/36 = 7/36 = 0.19444

Steve and Ed were comparing how much money they earned in a 9 week period. Steve earned $149.53 each week for three weeks. He then earned twice as much each week for the next six weeks. Ed earned $108.77 for two weeks. He then earned three times as much each week for the next seven weeks. How much more did Ed earn than Steve?

Answers

Steve: 149.53 x 3 = 448.59
299.06 x 6= 2242.95
2242.95 + 448.59 =
$2242.59

Ed: 108.77 x 2 = 217.54
326.31 x 7 = 2284.17
2284.17+ 217.54 = $2501.71

$2501.71 - $2242.95 =
$258.76

Ed earned $258.76 more than Steve.

Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fund-raising party. He put all the addresses in a bag and drew a random sample of 30 addresses. He then asked those families if they would help organize the fund-raising party. He found that 12% of the families would help organize the party. He claims that 12% of the neighborhood families would be expected to help organize the party. Is this a valid inference? No, this is not a valid inference because he asked only 30 families No, this is not a valid inference because he did not take a random sample of the neighborhood Yes, this is a valid inference because he took a random sample of the neighborhood Yes, this is a valid inference because the 30 families speak for the whole neighborhood
