Answer:
$25.66
Step-by-step explanation:
Given data
Total Bill before tax and tip= $27.30
Tax= 9%
Tip= 15%
Let us find the tax
=9/100*27.30
=0.09*27.30
=$2.457
Let us find the tip
=15/100*27.30
=0.15*27.30
=$4.095
Therefore his bill after tax and tip is
=27.30+2.457-4.095
=$25.66
PLEASE HELP ANGLE OF A TRIANGLE
Answer:
59°
Step-by-step explanation:
The angles of a triangle equal 180°.
Also the angle of a straight line is 180°.
So you first find the missing bottom angle by taking 180-147 to equal 33.
Then you take 33+88+x=180
solve for x by subtracting 88 and 33 from 180 to equal 59.
Answer:
59°
Step-by-step explanation:
180 - 147 = 33
88 + 33 = 121
180 - 121 = 59

Answer:
98 degrees
Step-by-step explanation:
We know that H is the same as G because the sides are marked equal.

In a triangle the measure of degrees in total is 180.
180 - 82 = 98
A test to detect an infection gives a positive result 98% of the time when an infection is present. It is 97% accurate when an infection is not present.
Answer:
false negatives - 2%
false positives - 3%
Step-by-step explanation:
Here is the complete question :
A test to detect an infection gives a positive result 98% of the time when an infection is present. It is 97% accurate when an infection is not present.
% of results will be false negatives, and % of results will be false positives.
False negative means a negative result which in actuality it is positive
False negative = 100% - percent of positive result
100% - 98% = 2%
False positive result means a positive result which in actuality is negative
False positive = 100% - percent of false positive
100 - 97 = 3%

What does intercept mean in the expression slope-intercept form?What does intercept mean in the expression slope-intercept form?
Answer:
The intercept is the coordinate by which a line crosses the x or y-axis. in the slop-intercept form, the intercept is for the y-axis and is included at the end of the formula as 'b,' bound by either adding or subtracting. Ex. y= 2x+6. y-intercept=6

Answer:
B. sometimes
Step-by-step explanation:
Consecutive angles of a parallelogram are same side interior angles of two parallel lines cut by a transversal, so they are always supplementary.
Supplementary angles are two angles whose measures add to 180 deg.
If two angles are supplementary and one angle measures 90, then the other angle also measures 90 deg, and the two angles are congruent. If one angle measures less than 90 deg, then the other measure more than 90 deg and are not congruent. Therefore, these angles may or may not be congruent.

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The table represents a linear function.
Let Two points on the line are (- 2, 8) and (- 1, 2).
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 8) / (-1 - (-2))
m = - 6 / 1
m = - 6
Thus, The slope of the function showing by table is,

Addison earned a score of 510 on Exam A that had a mean of 550 and a standard
deviation of 40. She is about to take Exam B that has a mean of 26 and a standard
deviation of 5. How well must Addison score on Exam B in order to do equivalently
well as she did on Exam A? Assume that scores on each exam are normally
distributed.
Answer:
21
Step-by-step explanation:
Algebraic Method: Find Z-Score for Exam A
[tex]z=\frac{x_A-μ_A}{σ_A}[/tex]
[tex]z=\frac{510-550}{40}[/tex]
[tex]z=\frac{-40}{40}[/tex]
[tex]z=-1[/tex]
Addison scored 1 standard deviation below the mean.
Plug Z into formula for Exam B:

[tex]-5=x_B-26[/tex]
[tex]21=x_B[/tex]
Addison would have to score 21 on Exam B

Complete the table for the given rule.
Rule:y= 4/1 x+1y
Answer: 2, 3, 4
Step-by-step explanation:
In the table graph provided, you will a column that has "x" as it's title. Under x, 4, 8, and 12 should listed. You figure out the answers for y by inputting the x value into the rule: y = 1/4x + 1.
For y = 1/4(4) + 1, you would multiply 1/4 by 4 and since the fours eliminate one another, you would get 1. Now, you would do 1 + 1, which equals 2. For y = 1/4(8) + 1, you would multiply 1/4 by 8 and since four and eight share the number four as their greatest common factor, four would be eliminated and eight would be reduced to 2. Now, you would do 2 + 1, which equals 3.For y = 1/4(12) + 1, you would multiply 1/4 by 12 and since four and twelve share the number four as their greatest common factor, four would be eliminated and twelve would be reduced to 3. Now, you would do 3 + 1, which equals 4.

An automobile factory wants to produce a total of 210 cars during three shifts. If the first shift produces two-fifths of the cars and the second shift produce one-third of the cars, what fraction of the total cars does the third shift need to produce?
Answer:
Step-by-step explanation:
answer below
Answer: 4/15
Step-by-step explanation: Total Cars to be produced in three Shifts = 210
Fraction of total cars to be produced in First Shift = 2/5
Fraction of total cars to be produced in second Shift = 1/3
Summation of all the fractions of total cars to be produced in all the three shifts should be equal to 1
Hence, fraction of total cars to be produced in third Shift = 1- (2/5) - (1/3)
= ( 15 - 6 - 5)/15 ( taking LCM of 5&3)
= 4/15
