Answer:
0.076 ; 1.924
Step-by-step explanation:
Given that :
_______Downtown Store ___ North Mall Store
n _______25 _______________20
Mean (m) _ $9 _______________$8
Sample sd_ $2 ______________$1
Standard Error (SE) = √[(s1²/n1) + (s2²/n2)]
√((2^2/25) + (1^2/20)) = 0.4582575
df = (25 + 20) - 2= 43
(m2 - m1) ± t(df = 43 , 0.025) * SE
(9 - 8) ± 2.01669 * 0.4583
(1 - 0.9242) ; (1 + 0.9242)
0.076 ; 1.924

Rachel is pouring a concrete patio. Her patio will be 6 inches deep, 6 feet long and 8 feet wide. If she rounds up to the nearest hundredth, how many cubic yards of concrete will she need? (Remember, yd3=in3÷46,656 )
Answer:
2.6667yd^3
Step-by-step explanation
Volume of the concrete = Length * width * height
Given
height = 6 inches
To yards;
1 in = 0.0277778yd
6 in = 6 * 0.0277778
6in = 0.1666668 yards
Width = 8 feet
Length = 6ft
LW = 48ft²
To yards;
1 ft = 0.333333yd
48 ft = 48(0.333333)
48 ft^ 2 = 15.999984yd^2
Volume = 15.999984 * 0.1666668
Volume = 2.6667 yd^3
Hence she will need 2.6667yd^3 concrete

Use a power-reducing formula to rewrite the given expression in terms of the first power of the cosine:
tan^2(8x)
tan²(8x) = sin²(8x) / cos²(8x)
… = (1 - cos²(8x)) / cos²(8x)
… = 1 / cos²(8x) - 1
… = 2 / (1 + cos(16x)) - 1
where the last equality follows from the half-angle identity for cosine,
cos²(x) = (1 + cos(2x)) / 2

Answer:
The value of h(45) ⇨ 5 | B Choice.
Step-by-step explanation:
[tex]h(x)=\frac{1}{9}(90-x)[/tex]
⟺ Find the value of h(45), substitute x = 45 in h(x)
[tex]h(45) = \frac{1}{9}(90-45)\\h(45)=\frac{1}{9}(45)\\h(45)=5[/tex]
Thus, the answer is 5.

$3,450 received in baby gifts. If no deposits or withdrawals are made, what is
the balance of the account if it earns simple interest at 5% for 18 years?
I
Answer:
I think you have to do ( 3,450 x .05 ) x 18
Sorry if i'm wrong.
Balance at end is $6,555
Given that;Amount deposit in bank = $3,450
Rate = 5% = 0.05
Number of year = 18 year
Find:Balance at end
Computation:I = PRTBalance at end = PRT + Amount deposit in bank
Balance at end = (3,450)(0.05)(18) + 3,450
Balance at end = 3,105 + 3,450
Balance at end = $6,555
