If the code for CAB is DEK, what is the code for BED?

Mathematics
1 answer:
snow_tiger [21]3 years ago

Answer:

CIM

Step-by-step explanation:

C is the 3rd letter of the alphabet, A is the 1st, and B is the 2nd.

CAB = 3,1,2

Repeating for DEK:

DEK = 4,5,11

Comparing:

4−3 = 1

5−1 = 4

11−2 = 9

BED = 2,5,4, so adding the corresponding numbers:

2+1 = 3

5+4 = 9

4+9 = 13

So the code is CIM.

13. Solve for m. Assume that none of the denominatons are equal to 0<br>Plz help me​
givi [52]

Answer:

m = (ps - b - uxs/t) / ux/t - p

Step-by-step explanation:

ux/t +b/m+s =p

multiplying throughout by (m+s) we get:

ux/t(m+s) + b = p(m+s)

open the brackets:

uxm/t + uxs/t + b = pm + ps

bring on one side of the equal sign all terms containg m, to make it the subject:

m(ux/t - p) = ps - b - uxs/t

m= (ps - b - uxs/t) / ux/t - p

During a sale, a store offered a 15% discount on a TV that originally sold for $900. After the sale, the discounted price of the
iVinArrow [24]
<h3>Answer:   98%</h3>

==================================================

Explanation:

The customer saves 15%, but still pays the remaining 85%. The two percentages add to 100%.

85% of $900 = 0.85*900 = 765

After the 15% discount is applied, the customer would pay $765

---------

Then after the sale, the price is marked up by 15%

This means we'll multiply by 1.15 to indicate a 15% increase

1.15*765 = 879.75

Notice that we don't get back to the original price (900) even though we increased by the same percentage as before. This is because 15% of a smaller number is a smaller amount; ie we have a smaller increase compared to the decrease earlier.

---------

Afterwards, divide the value 879.75 over the original price of $900

879.75/900 = 0.9775

Move the decimal point two spots to the right to end up with 97.75%

That percentage rounds to 98% when rounding to the nearest whole percent.

masya89 [10]

Answer:

a) H0 : P = 0.07

   Ha : P ≠ 0.07

b) p -value = 0.1770

Step-by-step explanation:

P = 7% = 0.07

x (result ) = 7 , n = 163

p = x / n = 7 / 163 = 0.043

<u>a) Using a significance level ( ∝ ) of 0.05, estimate the appropriate hypothesis</u>

H0 : P = 0.07

Ha : P ≠ 0.07

conduct a  Z- test statistic

Z = ( p - P ) / \sqrt{\frac{P(1-P)}{n} }

  = ( 0.043 - 0.07 ) / \sqrt{\frac{P(1-P)}{n} }  =  - 1.35

Critical value ( Z₀.₀₂₅ ) = ± 1.96

<em>we fail to reject H0 given that | z | < Zcritical because there is not enough evidence to conclude that proportion change</em>

<u>b) Determine the p-value of the test </u>

P-value = P ( | Z | > Z )

             = 2 * P ( Z < -1.35 )

             = 0.1770

The p-value ( 0.1770 ) > ∝ ( 0.05 ) hence we fail to reject H0 ( i.e. the conclusion agrees with part a above )
