Answer:

We choose D

Step-by-step explanation:

Given that:

  • ∠BOA = (3x -28) degrees
  • ∠COD = (66 -x) degrees
  • ∠BOC = 90 degrees

As we know that ∠BOA + ∠COD + ∠BOC= 180 degrees because AD is a straight line, so we have:

(3x -28) + (66-x) +90 = 180

<=> 2x = 52

<=> x = 26 degrees.

=> ∠BOA = 3*26 - 28 = 50 degrees

As we can see that, ∠BOA = ∠DOE (The properties of two straight lines intersect)

<=> ∠DOE  = 50 degrees

Once again, the  AD is a straight line, so we have:

∠DOE + ∠AOE = 180

<=> ∠AOE = 180  - ∠DOE

<=>  ∠AOE = 180  - 50 = 130 degrees

We choose D

Find (a) the range and (b) the standard deviation of the data set 40,35.45,55,60. Round to the nearest hundredth if necessary.
zmey [24]

Answer:

(a) 25

(b) 9.27

Step-by-step explanation:

Step 1

We have to rearrange the given days set from least to highest

35, 40, 45, 55, 60

(a) the range

Range = The highest number - The least number

= 60 - 35

= 25

(b) the standard deviation of the data set

35, 40, 45, 55, 60.

We find the Mean

Mean = Sum of values/Number of values

= 35+40+45+55+60/5

= 235/5

= 47

We can find the standard deviation now.

The formula =

√(x - Mean)²/n

= √(35 - 47)²+ (40 + 47)² + (45 - 47)² + (55 - 47)² + (60 - 47)²/5

= √144 + 49 + 4 + 64 +169/5

= √430/5

= √86

= 9.273618495

Approximately = 9.27

Find X.<br> Round to the nearest tenth.<br><br> Law of Cosines : c2 = 22 + b2 - 2ab cos C
fiasKO [112]

Answer:

70.5°

Step-by-step explanation:

22² = (20)²+(18)² - 2(20)(18) cos X

484 = 400 + 324 - 720 cos X

-240 = -720 cosx

1/3 = cos X

cos^{-1}(\frac{1}{3}) = X

X = 70.52877937

Artemon [7]

Answer:

Part A

The probability of the treatment groups mean being greater than the control group mean by 8points or more = (26+8+2)/1000 = 0.036

Part B

Yes, the result is statistically significant because the probability of the difference being 8point or more is less than 5% significant level

Part C

The answers is 0.036 means that there is a very little chance of obtaining difference of 8points or more by random chance. So, if the difference between treatment group mean and control group mean is at least 8 , then the result is significant which means protein shaken is actually helpful in speeding up the weight-10 process
