Answer:

Option (D)

Step-by-step explanation:

Mean=\frac{Sum of observations}{Number of observations}

here, observations are

1×1=1

2×2=2

3×3=9

4×1=4

5×1=5

6×2=12

7×3=21

8×1=8

9×1=9

10×0=0

hence, sum of observations =1+4+9+4+5+12+21+8+9+0=73

Number of observations are=1+2+3+1+1+2+3+1+1+0=15

Mean=\frac{73}{15}

Mean=4.8..

nearest to 5 .

Hence, option (D) is correct.

CAN SOMEONE PLEASE HELP ME ASAP PLEASEE ANYBODY LITERALLY ANYONE OUT THERE PLEASE. Determine m∠ABQ and determine m∠BCR.
s2008m [1.1K]

Answer:

ABQ  = 139

BCR is the same as QBC since they are alternate interior angles

BCR = 41

Step-by-step explanation:

CBQ and SCB are same side interior angles so they add to 180

2a-9  + 5a +14 = 180

Combine like terms

7a +5 = 180

Subtract 5 from each side

7a = 175

Divide by 7

7a/7 = 175/7

a = 25

ABQ  is the same as SCB  since they are corresponding angles so

ABQ = SCB = 5a+14 = 5*25+14 = 125+14 = 139

BCR is the same as QBC since they are alternate interior angles

BCR = QBC = 2a-9 = 2*25 -9 = 50-9 = 41

spayn [35]

Step 1. Calculate the <em>pounds of broccoli</em>.

Start with what you know: you want 32 oz of broccoli.

You know that 1 lb = 16 oz.     Calculate the weight in pounds

Wt  = 32 × 1/16

Wt  = 2 lb

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

Step 2. Calculate the <em>cost of the broccoli</em>.

$1.50 = 1 lb          Calculate the cost
