Comparing forms, you see that
4 = ∛c
The value of c is found by cubing both sides of this equation.
4³ = c = 64
Answer:
length =29m width =11m
Step-by-step explanation:
length---L
width -----W
L=3W-4
area=319sqm
area of rectangle=L × W
area of rectangle =W ×(3W - 4)=319
expanding...
3W^2 - 4W=319
3W^2 - 4W -319=0
factorize
(W-11)(3W+29)=0
W=11 or -29/3
using the positive because the negative width with a minus sign does not make sense in real life, we use 11m
width =11m
length 3W -4=3(11) -4 =29m
N+7
Every time you add 7 you getbthat answer.
Answer:
(L+1)/2 = W

Answer:
A good prediction is that the number 5 will be rolled 8 times
Step-by-step explanation:
Here, we want to get the number of times 5 would occur in a roll of 50
firstly, we need the probability of having a 5 come up
To do this, we have to divide the number of 5’s by the count of possible numbers
We have this simply as 1/6
Now, we have to multiply this by 50
we have this as;
1/6 * 50 = 8.333
This is approximately 8
so we have it that in 50 rolls, we can have the number 5 coming up 8 times
