Answer:

slope is 10

y-intercept is 18

Step-by-step explanation:

The slope and y-intercept in y = 10x + 18 are 10 and 18 respectively.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given a line in slope-intercept form which is y = 10x + 18.

We know in y = mx + b, slope = m, and y-intercept = b.

∴ In  y = 10x + 18.

Slope = 10 and  y-intercept = 18.

x = 1, y = 1 - 5 = -4.

Answer:

249

Step-by-step explanation:

We can see that the difference of every term in the given sequence is 9, because -12 + 9 = -3, -3 + 9 = 6 and 6 + 9 = 15. We may therefore assume that the sequence is arithmetic (a fancy word of saying that a sequence is increasing with a constant value every term).

Since the difference of every term is 9, we know that the explicit form of the sequence (where the value of every term is expressed in terms of the term number) is in the form [tex]9n+c[/tex], where [tex]n[/tex] is the term number and [tex]c[/tex] is a constant we are going to figure out right now.

We know that the first term of the sequence is -12, so we see that[tex]9(1) + c = -12[/tex] and hence [tex]c=-21[/tex]. Therefore, the 30th term of the sequence is [tex]9(30) - 21 = 249[/tex].

Answer:

B)  81°

Step-by-step explanation:

∡1 ≅ ∡5 because they are corresponding angles

∡5 ≅ ∡7 because they are vertical angles

therefore, ∡1 ≅ ∡7

since the angles are equal we can create the following equation:

3x + 18 = 2x + 39

x + 18 = 39

x = 21

∡7 = 2(21) + 39

∡7 = 42 + 39

∡7 = 81

Answer:

yes i will!

Step-by-step explanation:

Let the variable be x

A number isn’t given so pick any number.

Let’s use 10

Set up the equation to get:

X + 10 = -8

Solve for the variable by subtracting 10 from both sides:

X = -18

Let the variable be y and pick any number, let’s use the number 2.

Equation: 2 x y = 4/5

Solve for y by dividing both sides by 2:

Y = 2/5

Answer:

GH = 15

Step-by-step explanation:

14. BC = 19

GH = 9x - 3

FE = 5x + 1

Given that GH is the midsegment of the trapezoid, therefore:

GH = (BC + FE)/2

Plug in the values

9x - 3 = (19 + 5x + 1)/2

9x - 3 = (20 + 5x)/2

Multiply both sides by 2

2(9x - 3) = 20 + 5x

18x - 6 = 20 + 5x

18x - 5x = 20 + 6

13x = 26

Divide both sides by 13

x = 2

✔️GH = 9x - 3

Plug in the value of x

GH = 9(2) - 3 = 18 - 3

GH = 15

   Total number of vanila flavored cupcakes sold in a day by the bakery is 415.

        Number of flavored cupcakes = percentage of vanila flavored

                                   cupcakes × Total number of cupcakes sold in a day

Total number of cupcakes sold by the bakery = 500

Percentage of the cupcakes having vanilla flavor = 83%

Number of vanila flavored cupcakes = 83% of 500

                                                             = [tex]\frac{83}{100}\times 500[/tex]

                                                             = 415

      Therefore, number of vanila flavored cupcakes sold by the bakery will be 415.

Answer:

0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Manufacturing Ball bearings are manufactured with a mean diameter of 5 millimeters (mm).

This means that [tex]\mu = 5[/tex]

With a standard deviation of 0.02 mm.

This means that [tex]\sigma = 0.02[/tex]

(a) What proportion of ball bearings has a diameter more than 5.03 mm

This is 1 subtracted by the pvalue of Z when X = 5.03. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{5.03 - 5}{0.02}[/tex]

[tex]Z = 1.5[/tex]

[tex]Z = 1.5[/tex] has a pvalue of 0.9332

1 - 0.9332 = 0.0668

0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm

Answer:

49°

Step-by-step explanation:

O=41° and G=90° (because it is a right angle).  The sum of the interior angles of a triangle is 180°.  So, add the known angles, 41°+90°=131°.  Since the sum of all three angles needs to be 180°, subtract the known angles from the total, 180°-131°=49°, to find the unknown angle.  

The angle D in triangle OGD measures 49 degrees.

To find the measure of angle D in triangle OGD, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

Given that angle O is 41 degrees and angle G is 90 degrees, we can substitute these values into the equation:

Angle O + Angle G + Angle D = 180

41 + 90 + Angle D = 180

131 + Angle D = 180

Now, we can solve for angle D by subtracting 131 from both sides:

Angle D = 180 - 131

Angle D = 49

Therefore, angle D in triangle OGD measures 49 degrees.
