Mass=Density*Volume
Density=1.1 g/cc
Volume of a cylinder: <span>π*r^2*h
</span>Radius of the top of the can: 3.57
Volume of this can: 480.47
480.47*1.1=528.517
If I'm correct the mass of this can should be 528.517
Answer:
Perimeter of the rectangle=Perimeter of the trapezium
2{(3x+4)+(4x)}=2(5x)+(x-3)+(7x-3)
→2(7x+4)=10x+x-3+7x-3
→14x+8=18x-6
→4x=14
→x=7/2
<u>→</u><u>x=3.5</u>
The value of x is <u>3.5 cm</u>
Answer:
1469.5
Step-by-step explanation:
when rounding to whichever place always look at the number to the right of the spot you are rounding to
since "2" is less than 5 we ignore all the numbers after the tenths place
hope this helps!
Answer:
Step-by-step explanation:
We would apply the formula for binomial distribution. It is expressed as
P(x = r) = nCr × q^(n - r) × p^r
Where
n = number of samples
p = probability of success.
q = probability of failure
From the information given,
n = 12
p = 90% = 90/100 = 0.9
q = 1 - p = 1 - 0.9 = 0.1
28) Probability that at least 10 are ripe within 4 days is expressed as
P(x ≥ 10) = P(x = 10) + P(x = 11) + P(x = 12)
P(x = 10) = 12C10 × 0.1^(12 - 10) × 0.9^10 = 0.23
P(x = 11) = 12C11 × 0.1^(12 - 11) × 0.9^11 = 0.38
P(x = 12) = 12C12 × 0.1^(12 - 12) × 0.9^12 = 0.28
P(x ≥ 10) = 0.23 + 0.38 + 0.28 = 0.89
29) Probability that no more than 9 are ripe within 4 days is expressed as
P(x ≤ 9) = 1 - P(x ≥ 10)
P(x ≤ 9) = 1 - 0.89 = 0.11
Answer: x < -2.861353
Step-by-step explanation:
simplify to: 0.69897x <-2
divide both sides by 0.69897
0.69897/0.69897 < -2/0.69897
so the answer is x < -2.861353
