Aldo’s coffee shop makes a blend that is a mixture of two types of coffee.Type A coffee costs 5.6 per pound. Type B costs 4.05 p

Pie

Answer: 93

Step-by-step explanation: $\\$ Since 160 cups of blend are sold , this means

$\\$ A + B = 160

$\\$ Since Type A is sold for 5.6 per pound , that means the total number of A sold = 5.6A

$\\$ Also , Type B is sold for 4.05 per pound , the total number of B sold = 4.05B

$\\$ And it was given that the total cost of blend = 751.85 , then

5.6A + 4.05B = 751.85

$\\$ A + B = 160 ............................. eqn 1

$\\$ 5.6A + 4.05B = 751.85 ..................... eqn II

$\\$ From eqn I , A = 160 - B ................ eqn III

$\\$ Substitute A = 160 - B into equation II , then we have:

$\\$ 5.6(160 - B) + 4.05B = 751.85

$\\$ Expanding , we have

$\\$ 896 - 5.6B + 4.05B = 751.85

$\\$ 896 - 1.55B = 751.85

$\\$ collecting the like terms

$\\$ 1.55B = 896 - 751.85

$\\$ 1.55B = 144.15

$\\$ Therefore B = 144.15/1.55

$\\$ B = 93

The area of a parallelogram is given by the formula A=bh the area of the parallelogram on the right is 126 sq units. Find its ba

Elden [556K]

From the diagram we have

Base = $4x+1$
Height = $x+1$

Area = Base × Height
126 = $(4x+1)(x+1)$ ⇒ Expand the double bracket
126 = $4x^{2}+5x+1$ ⇒ Subtract 126 both sides
0 = $4x^{2}+5x-125$ ⇒ Factorise the quadratic expression
0 = $(x-5)(4x+25)$ ⇒ Equating each factor to zero

$x-5=0$ $4x+25=0$
$x=5$ $x=- \frac{25}{4}$

We need the positive value of $x$ so we use $x=5$

Height = 5+1 = 6
Base = 4(5)+1 = 21

30. If the level of significance is 0.05 and the p-value is 0.04, what conclusion can you draw?

Inessa [10]

Answer:

Reject null hypothesis

Step-by-step explanation:

Because our p-value of 0.04 is less than the level of significance of 0.05, then we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist
