Step-by-step explanation:

If it is parallel with the line 2x-3y=9

Both of them have same slope so

2x-3y=9 turn this into slope intercept form first

-3y=9-2x

Y=9/-3 + -2x/-3

Y=2/3x - 3 the slope of this equation is ⅔

So our new equation will be

Y=⅔x +b

Since (6,7)

On the line

6=⅔(7)+b

b= 6-14/3=4/3

Y=⅔x+4/3 (slope intercept form)

3y-2x=4 ( general equation of line )

The equation of the line that passes through the point (6, 7) and is parallel to the line 2x - 3y = 9 is 3y -2x = 19

The equation of a line in point slope form is expressed as

y-y0 = m(x-x0)

m is the slope of the line

(x0, y0) is the point on the line.

Given the equation 2x - 3y = 9

Rewrite in standard form y = mx + b

-3y = -2x + 9

y = 2/3 x - 3

Compared with the standard, the slope of the line is 2/3

Substitute the slope and the point into the point slope equation.

y - 7 = 2/3 (x - 6)

3(y-7) = 2(x-6)

3y - 21 = 2x - 2

3y - 2x = 19

Hence the equation of the line that passes through the point (6, 7) and is parallel to the line 2x - 3y = 9 is 3y -2x = 19

The z-score for data item 56, with a mean of 60 and a standard deviation of 4, is -1.

Option B is the correct answer.

We have,

To convert a data item to a z-score, you can use the formula:

z = (x - μ) / σ

Where:

z = z-score

x = data item

μ = mean

σ = standard deviation

In this case, the data item (x) is 56, the mean (μ) is 60, and the standard deviation (σ) is 4.

Plugging these values into the formula.

z = (56 - 60) / 4

z = -4 / 4

z = -1

Therefore,

The z-score for data item 56, with a mean of 60 and a standard deviation of 4, is -1.

Answer:

-840

Step-by-step explanation:

"Product" means to multiply, so you multiply -24 by 35. Since -24 has a negative, negative times a positive will equal a negative number.

(Negative times negative is positive.)

(Negative times positive is negative.)

(Positive times positive is obviously positive.)

The angle according to the given data about the triangle will be equal to 7°.

An angle results from the intersection of two lines at a point. The term "angle" describes the width of the "gap" that exists between these two rays. It's represented by the symbol ∠.

Angles are most frequently measured in degrees and radians, a measurement of roundness or rotation. Angles are a part of everyday existence.

As per the given information in the question,

The length of the sides is given as:

l = 8.7 cm

m = 2.3 cm

n = 6.6 cm

Use the formula given below to find the angle,

a² = b² + c² - 2bc cos A

The formula modified to the information will be,

m² = n² + l² - 2nl cos M

2.3² = 6.6² + 8.7² - 2(6.6)(8.7)cos M

5.29 = 43.56 + 75.69 - 114.84 cos M

-119.25 + 5.29 = -114.84 cos M

cos M = 113.96/117.84

M = cos⁻¹ 0.992

M = 7.09 ≈ 7°.

Answer:

The camera is sold for $ 59.26.

Step-by-step explanation:

From the statement we understand that the new price of the camera ([tex]C'[/tex]) is calculated by:

[tex]C' = \frac{C_{o}}{\left(1+\frac{r}{100} \right)}[/tex] (1)

Where:

[tex]C'[/tex] - Price after increase, measured in US dollars.

[tex]r[/tex] - Increase rate, expressed in percentage.

If we know that [tex]C_{o} = 80\,USD[/tex] and [tex]r = 35[/tex], then the new price of the camera is:

[tex]C' = \frac{80\,USD}{1+\frac{35}{100} }[/tex]

[tex]C' = 59.26\,USD[/tex]

The camera is sold for $ 59.26.

Danny got 35/45 answers correct.

Divide 35 into 45

35 ÷ 45 = .777777778

.777777778 ≈ .78

To convert a decimal to a percentage, move the decimal point two spaces behind.

.78 = 78%

The expected test score for a student who did not study is 40.

Option C is the correct answer.

We have,

Given that the line on the graph passes through the points (2.5, 60) and (5, 80), we can use this information to estimate the expected test score for a student who did not study.

Let's calculate the slope of the line using the two given points:

Slope = (change in y)/(change in x)

= (80 - 60)/(5 - 2.5)

= 20/2.5

= 8

The slope of the line is 8, which indicates that for every additional hour spent studying, the test score increases by 8 points.

Since we are looking for the expected test score for a student who did not study (0 hours spent studying), we can substitute x = 0 into the equation of the line to find the corresponding y value (test score).

y = mx + b (where m is the slope and b is the y-intercept)

Using the given points, we can find the y-intercept (b) by substituting one of the points into the equation:

60 = 8(2.5) + b

60 = 20 + b

b = 60 - 20

b = 40

The equation of the line is y = 8x + 40.

Now, substitute x = 0 into the equation to find the expected test score:

y = 8(0) + 40

y = 0 + 40

y = 40

Thus,

The expected test score for a student who did not study is 40.

Answer:

X = 38° and w = 65°.

Step-by-step explanation:

Hey there!

Looking through figure, we get;

(3x + 1)° = (2x + 9)° + 30° { Exterior angle of triangle is equal to the sum of opposite adjacent interior angles}

(3x + 1)° = 2x + 9° +30°

or, 3x - 2x = 39° - 1°

x = 38°

X = 38°

Therefore, x = 38°

For w:

(3x + 1)° + w = 180° (being linear pair)

(3*38+1 )°+ w = 180°

115°+ w = 180°

w = 180° -115°

Therefore, w = 65°
