Answer = $39.78
100-20 =80
100-25=75
Multiply 60 x .80 to get $48
Then multiply 48 x .75 to get $36
Sales tax %10.5 = move decimal two places to left .105
Now multiply 36 x .105 =3.78
$3.78 equals your sales tax
Finally add $3.78+$36= $39.78
P = 2(L+W) where L = Length and W = Width.A = L*WYou are given that P = 300m and A = 5000 sq.m. so plug these values into the two equations thus:300 = 2(L+W)5000 = L*WNow you have a system of equations with two unknowns.Solve equation 1a) for LL = 150-W now substitute this into equation 2a) and solve for W.5000 = (150-W)*W Simplify this.W^2-150W+5000 = 0 This quadratic equation can be solved by factoring, so...(W-100)(W-50) = 0So W = 100 or W = 50Now we need to find L and we can use equation 1b.L = 150 - W and, if W = 50m, then:L = 100m or, if W = 100m, then:L = 50m.The dimensions of the garden are: 100m by 50m
Answer:
ayy thank you very much lol
Answer: B. You may use the t procedure, provided your sample size is large, say, at least 30.
Step-by-step explanation: To use a T test hypothesis, the following steps is considered;
1. Add the test hypothesis when using a T test module in the experiment
2. Add the date set that contains the columns that is to be analyzed
3. Decide which kind of T test is appropriated for the data
4. If single sample is been used, the adequate parameters should be used.
The correct statement in this case is "You may use the t procedure, provided your sample size is large, say, at least 30."
