Assume a random sample of the birth weights of 186 healthy babies has a mean of 3103 g and a standard deviation of 696 g. Construct a 95% confidence interval estimate of the mean weight of all healthy babies born to healthy mothers. What does the interval suggest about a recent study informing soon-to-be-parents that they can expect their new baby to weigh about 2980 g?


3002 g < μ < 3204 g; the 2980 g weight is less than the range values of the interval; however, it is close to the interval and could therefore easily represent an expected mean weight of new babies.


3002 g < μ < 3204 g; the 2980 g weight falls below the interval, suggesting that it is unlikely to be an expected value and is likely too low to represent an accurate population mean.


2879 g < μ < 3080 g; the interval suggests 3103 g is not a likely mean, proving the sample is biased; the recent study should be used as a basis for estimating new birth weights.


2879 g < μ < 3080 g; the 2980 g weight falls comfortably in the interval, which suggests that 2980 g is very likely to represent an accurate population mean of birth weights.

Write the equation of the line fully simplified slope-intercept form

Answers

Answer:

y=mx+b

Step-by-step explanation:

Answer:

y = (5/2)x - 5

Step-by-step explanation:

SLOPE:

The slope is rise over run, and in this case (thanks to the graph), we can do the [difference of y] / [difference of x] pretty easily. This is 5 / 2

Y-INTERCEPT:

Y-intercept is simple: where the line touches the y-axis. This happens at y = -5.

Therefore, the equation y = (5/2)x - 5

The slope is 0 because it is a straight line

Step-by-step explanation:

Answer:

undefined.

Step-by-step explanation:

You could be really formal and use the slope formula

The y values are both the same -- 4.

The x values are 3.5 and 6.5

Therefore  the slope is (6.5 - 3.5) / (4  -  4)

The denominator is 0

The slope is undefined because 3/0 is not very well behaved.

A horizontal line always gives an undefined amount.

Answers

Answer: option B

Step-by-step explanation:

-4, 1, 3

The roots of the polynomial equation x³ - 7x = 6x - 12 is given by the values x = -4 , 1 , 3

What is a polynomial?

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the polynomial equation be represented as A

Now , the value of A is

x³ - 7x = 6x - 12   be equation (1)

Now , it can be represented as 2 equations of the form

A = x³ - 7x   be equation (2)

And , B = 6x - 12    be equation (3)

On plotting the graphs of the two equations , we get

The point of intersection of the equations is at P ( -4 , -36 ) , Q ( 1 , -6 ) and R ( 3 , 6 )

Therefore , the x coordinates of the points are x = -4 , 1 , 3

Hence , the roots of the polynomial is x = -4 , 1 , 3

A company makes a profit of $1.38 million. This is $2.54 million more than last year. Write and solve an equation to find the profit p (in millions of dollars) last year. An equation is =1.38.

Answers

Answer: Required equation : 1.38 = p +2.54

Last year profit = $ -1.16 million or we can say loss =$ 1.15 million

Step-by-step explanation:

Given :  A company makes a profit of $1.38 million. This is $2.54 million more than last year.

Profit this year = 2.54 + Profit in last year

Let p = profit (in millions of dollars) last year.

Then, 1.38 = p +2.54   , is the required equation.

⇒ p = 1.38-2.54

⇒ p= -1.16, which is loss because of negative sign.

Hence, last year profit = $ -1.16 million or we can say loss =$ 1.15 million

Answer: The profit from 2021 = $ -1.16 Million ($1.16 Million loss)

Step-by-step explanation:

Profit for 2022 = $ 1.38 Million

Profit for 2021 = Profit for 2022 - $ 2.54 Million

Algebraic equation:

p2021 = p2022 -$ 2.54 Million

p2021 = $ 1.38 Million - $ 2.54 Million

p2021 = $ -1.16 Million

Gabe bought five sacks of apples each sack weighed 12 lb he paid three for each pound of apples what was the total cost of all of the apples Gabe bought

Answers

Answer:

The cost of 12lbs of apples is $36.

Step-by-step explanation:

Lets Solve!

⟹ First we must define x and y.

 x is the lb's of apples and y is the cost.

⟹ Now lets form our equation.

[tex]3x = y[/tex]

[tex]x = 12[/tex]

⟹ Since gabe bought 12 pounds of apples x = 12.

⟹ Now substitute x for 12.

[tex]3x = y[/tex]

[tex]3(12)= y[/tex]

⟹ Now multiply.

[tex]36 = y[/tex]

The cost of 12lbs of apples is $36.

For example, 134 would be 1.34 times 10^2.

101 = 10.
