During one month, a homeowner used 600 units of electricity and 100 units of gas for a total cost of 390. The next month, 400 units of electricity and 250 units of gas were used for a total cost of $326. Find the cost per unit of gas.

Answers

Answer:

cost per unit of gas i.e y= 0.36

Step-by-step explanation:

Let cost per unit of electricity = x

and cost per unit of gas = y

The equations required will be:

[tex]600x+100y=390 ---- eq(1)\\400x+250y=326----eq(2)[/tex]

We need to find value of y i.e cost per unit of gas

Solving equations to find value of y

We will use elimination method

Multiply equation 1 by 4 and 2 by 6

[tex]2400x+400y=1560 ---- eq(1)\\2400x+1500y=1956----eq(2)[/tex]

Subtracting eq 1 from eq 2

[tex]2400x+1500y=1956----eq(2)\\2400x+400y=1560 ---- eq(1)\\- \ \ \ \ \ - \ \ \ \ \ \ \ \ \ \ -\\----------------\\1100y=396\\y=\frac{396}{1100}\\y=0.36[/tex]

Solving we get y=0.36

Putting value of y in eq(1) to find value of x

[tex]600x+100y=390\\600x+100(0.36)=390\\600x+36=390\\600x=390-36\\600x=354\\x=\frac{354}{600}\\x=0.59[/tex]

Value of x = 0.59

But we need to find only cost of unit of gas i.e y

So, cost per unit of gas i,e y= 0.36

A coin is tossed 5 times; find the probability of getting at least 1 tail. Would you consider this event likely to happen?

Answers

Answer: 0.96875

Step-by-step explanation:

Probability of obtaining at least one tail on a toss of coin 5 times ;

P(success) in a coin toss = 1/2 = 0.5

Using the binomial distribution formula :

P(x) = nCx * p^x * (1 - p)^(n-x)

P(at least one tail) = 1 - p(0 tails)

P( 0 tails) = 5C0 * 0.5^0 * 0.5^(5-0)

= 1 * 1 * 0.03125

= 0.03125

P(at leat 1 tail) = 1 - 0.03125

P(atleast 1 tail) = 0.96875

The mean profit is $

Answers

Answer:

-48

Step-by-step explanation:=-48

The mean profit of the fruits will be $75.

What is mean?

Mean is defined as the ratio of the sum of the number of data sets to the total number of data. The mean is just like an average it is calculated by taking the ratio of the sum of all the numbers to the total count of the numbers.

Given that the weekly profit of the fruits is $125, $86, $54, and $35. The mean will be calculated as:-

Mean = ( 125 + 86 + 54 + 35 ) / 4

Mean = 300 / 4

Mean = $75

Therefore, the mean profit of the fruits will be $75.

On the basis of a survey of 545 television viewers, a statistician has constructed a confidence interval and estimated that the proportion of people who watched the season premiere of Glee is between .16 and .24. What level of confidence did the statistician use in constructing this interval?

Answers

Answer:

0.98 also 98%

Step-by-step explanation:

In this question we have the Lower limit to be 0.16

We have the Upper limit to be 0.24

Such that (0.16+0.24)/2 = 0.40/2 = 0.20

Standard deviation= √(0.2x0.8/545) this gives 0.017134

Next we get margin of error

Margin of error = 0.24-0.20 = 0.04

Z multiplied by sd =0.04

Such that

Z = 0.04/0.017134 =2.33

On this z score, the Corresponding level of confidence is 0.98

Which is 98%

Find the missing angle:

Answers

Answer:

Step-by-step explanation:

Use this picture as a reference.

So, using remote angles theorem, which states that; the angle formed from the extension of a side in a triangle is equal to the sum of the two angles which it does not make contact with, within the triangle. One can conclude that :

m< BCD = m<B + m<A

substitute:

m<BCD = 80 + 25

Simplify:

m<BCD = 105

Since it is given that m< BCE is 50, then one has to subtract m<BCE from m<BCD to get m<ECD

m<BCD - m<BCE = m<ECD

Subsitute:

105 - 50 = m<ECD

Simplify:

55 = m<ECD

Using the sum of angles in a triangle, which states that the sum of all the angles in a triangle is 180 degrees, one can say that:

m<D + m<ECD + m<E = 180

Substitute:

85 + 55 + m<E = 180

Simplify, inverse operations:

140 + m<E = 180

-40 -140

m<E = 40
