Answer:

The corect answer is $77,06.

Step-by-step explanation:

First let's start by analyzing the information we have:

This is what Yvette spent for each product:

A 26 pound turkey for $1.49 per pound: 26 x 1,49 = 38,74

Two bags of potatoes for $5.75 each: 5,75 x 2 =11,50

6 pounds of stuffing for $2.47 per pound: 2,47x6 =14,82

8 cans of pumpkin for $1.50 each: 8x1,50=12

Once we have these results we just have to add them in order to get the final result of all the money Yvette spent:

38.74 + 11.50 + 14.82 + 12 = 77.06

The correct answer is 77.06.

State the equation of the line which has the y-intercept :

aliina [53]

Answer:

A general line is written as:

y = a*x + b

where:

a is the slope

b is the y-intercept.

a) y-intercept = 2 and slope = 7.

This line is:

y = 7*x + 2

b) y-intercept = -1 and is parallel to y= 5x - 7.

Now, if two linear equations are parallel if they have the same slope and different y-intercept. Then if we want a line parallel to y= 5x - 7, this means that the slope of this line must also be equal to 5.

y = 5*x + (-1)

c) y-intercept 2 and is inclined at 45° to the x- axis.

When we have an inclination of A degrees from the x-axis, the slope of the equation is given by: a = Tan(A)

In this case, we have A = 45°

Then the slope is a = Tan(45°) = 1

Then the equation of this line is:

y = 1*x + 2

What number exceeds 23 by 4 more than twice the amount by which 15 by -3

hodyreva [135]

Answer:

The required number is 63

Step-by-step explanation :

Let the number be x

Now As per question , the equation is written as

x - 23 = 2 × [ 15 - ( - 3) ] + 4

Or, x - 23 = 2 × ( 18) + 4

Or , x - 23 = 36 +4

Or, x - 23 = 40

So, x = 40 + 23

∴ x = 63

Hence the required number is 63 Answer

The two intervals (114.9, 115.7) and (114.6, 116.0) are confidence intervals (computed using the same sample data) for μ = true

kenny6666 [7]

Answer:

115.3 hertz

Step-by-step explanation:

For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.

For the first interval:

$M=\frac{114.9 + 115.7}{2} \\M=115.3\ hertz$
