Answer:
9 boards
Step-by-step explanation:
2/3 of the porch= 6 boards
so to figure out how much one third of the porch needs you find half of what it takes to fill in 2/3 of the porch and you get 3.
so 3=1/3 of the porch
then you simply do 3times 3 or 3+3+3 and you get 9
so it takes 9 boards to fill the whole porch
Answer:0.8413
Step-by-step explanation:
Mean= 188, Std Dev. =20.8, Z=(x-mean)/Std Dev
P(X less than 167.2)= P(Z less than (167.2-188)/20.8)
=P(Z less than (-20.8/20.8))
=P(z less than -1)= P(Z less 1)
The value of 1 in the normal distribution table is 0.3413
So we add 0.5 to 0.3413 =0.8413
Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt
Step-by-step explanation:
You must spend at least $93 and no more than $100.
2 dress shirts: $42 + 5 T-shirts: $60 = $102 too much money
2 dress shirts: $42 + 4 T-shirts: $48 = $90 too much money left
3 dress shirts: $63 + 3 T-shirts: $36 = $99 this works
4 dress shirts: $84 + 1 T-shirt: $12 = $96 this works
5 dress shirts: $105 too much money
Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt
