Answer:
42 apples
Step-by-step explanation:
Crazy Al is making apple pie. His recipe calls for 6 apples to every 1/4 cup of sugar. He want to use up all his sugar to make his pie. He has 1 3/4 cups of sugar, how many apples does he need to make his pie?
From the question, we know that:
1/4 cup of sugar = 6 apples
1 3/4 cups of sugar = x
Cross Multiply
1/4 × x = 1 3/4 × 6
x = 1 3/4 × 6/1/4
x = 7/4 × 6/ 1/4
x = 42/4 ÷ 1/4
x = 42/4 × 4/1
x = 42 apples
So width is l-16, l being the length. perimeter is 2w+2l=98. substitute w for l-16 for 2(l-16)+2l=98. Now, distribute to get 2l-32+2l=98. Add 32 to both sides for 2l+2l=130. then, 4l=130. divide both sides by four, so the length is 32.5. plug this into the original perimeter equation for 2w+2(32.5)=98. Again, distribute and subtract so your equation is 2w=33. Divide both sides by 2 so your width is 16.5
so width is 16.5 cm, and length is 32.5 cm
hope this helps!
Step-by-step explanation:
<h3>Given,</h3>
perimeter - 16cm
length - 5cm
find breadth,
perimeter of rectangle = l × b
16cm = 5 × b
b = 16/5
b = 3.2 cm
Over all it’s still a 1/3 of getting a 2 when rolling
Answer:
a) 0.2
b) 0
Step-by-step explanation:
E[X] = 0*P(X=0)+ 1*P(X=1)+2*P(X=2)+3*P(X=3)+4*P(X=4) = 0.8
(a) The largest possible value of P(X=4) occurs when
P(X=1) = P(X=2) = P(X=3) = 0.
In that case,
4*P(X=4) = 0.8 ===> P(X=4) = 0.8/4 = 0.2
(b) The smallest possible value of P(X=4).
Obviously, the smallest possible value is P(X=4) = 0
In that case, possible values for the remaining probabilities
could be, for example
P(X=0) = P(X=2) = P(X=3) = 0
P(X=1) = 0.8
