When adding two digit numbers u will be looking at the ones and deciding if they can regroup them for a ten. You might want to equate regrouping with trading a term that you will understand immediately you will begin to add 2 digit numbers by using ten and ones blocks. And the answer is (107)

When you do an addition problem like 77 + 23 you put each number on top of the other in either way you want to put (In addition) so if you reach a number that goes to ten or up to nineteen you will have to add a one to the seven if you end up at 20 you have to add 2 to the 7 but the only, but your case is different, You would have to add four plus three giving you a seven and and 6 plus 4 giving you a 10 so just put the 10 to the 7 giving you 107

Flura [38]

The other two expressions that have value of 256 is 4⁴ and 16².

Given the exponent expression 2⁸ has a value of 256.

We want to write two other exponential expressions that have value 256.

The given expression is 2⁸=256

The above expression can be written as

2×2×2×2×2×2×2×2=256

By using the Associative property of multiplication, we can write them as

(2×2)×(2×2)×(2×2)×(2×2)=256

4×4×4×4=256

4⁴=256

and it can also be written as by using the associative property of multiplication again and get

(2×2×2×2)×(2×2×2×2)=256

16×16=256

16²=256

Hence, the two other exponential expression of 256 other than 2⁸ is 4⁴ and 16².

Here is data on the percentage of 200 hotels in each of the three large cities across the world on whether minibar charges are c
zheka24 [161]

Answer:

Degree of freedom = 2

Expected frequency = 80%

Critical value, = 5.991

χ² statistic = 3.5

Step-by-step explanation:

Given the data :

Hong Kong New York Paris

Yes 86% 76% 78%

No 14% 24% 22%

The degree of freedom for the Chisquare statistic is given as :

(no of rows - 1) * (number of columns - 1)

Number of rows = 2

Number of columns = 3

. Degree of freedom = (2-1) * (3-1) = 1*2 = 2

Expected frequency = (Row total * column total) / grand total

The expected frequency of Hong Kong / Yes cell :

Row total = (86+76+78) = 240

Column total = (86+14) = 100

Grand total, N = (14+24+22)+240 = 300

Expected frequency = (240*100)/300 = 80%

The critical value :

At α - level = 0.05 ; df = 2

Critical value = 5.991

χ² = Σ(observed - Expected)² / Expected

The expected values :

80 80 80

20 20 20

Hence,

χ² = Σ(86-80)²/80 + (76-80)²/80 + (78-80)²/80 + (14-20)²/20 + (24-20)²/20 + (22-20)²/20

χ² statistic = 3.5
