Find the sum 78/100+1/10

Answer:

m = - 2 , c = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (3, 0 )

m = [tex]\frac{0-8}{3-(-1)}[/tex] = [tex]\frac{-8}{3+1}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (3, 0 )

0 = - 6 + c ⇒ c = 0 + 6 = 6

Answer:

See each problem below.

Step-by-step explanation:

1. The 3 streets, North, Center, and South are parallel.

Avenue A is perpendicular to North Street.

That means the angles formed by North Street and Avenue A are right angles. Because of corresponding angles and parallel lines, the angles formed by Avenue A with Center Street and also the angles formed by Avenue A and South Street are also all right angles. That makes those corresponding angles congruent. That makes Avenue A and South Street perpendicular.

2. One angle is corresponding to the 70° angle and also measures 70°. The adjacent angle to the 70° angle is supplementary to it and measures 110°.

70°, 100°

3. Angles ACB and ACD form a linear pair and are supplementary. That means that the sum of their measures is 180°.

m<ACB + m<ACD = 180°

5x + m<ACD = 180

m<ACD = 180 - 5x

4. Angles BCF and CFE are same side interior angles of parallel lines cut by a transversal, so they are supplementary.

m<BCF + m<CFE = 180°

4x + 11x = 180

15x = 180

x = 12

m<BCF = 4x = 4(12) = 48

m<CFE = 11x = 11(12) = 132

m<BCF = 48°

m<CFE = 132°

5.

Angles CFG and DCF are same side interior angles of parallel lines cut by a transversal, so they are supplementary.

m<BCF + m<CFE = 180°

(3x) + (7x + 40) = 180

10x = 140

x = 14

m<CFG = 3x = 3(14) = 42

m<DCF = 7x + 40 = 7(14) + 40 = 138

m<CFG = 42°

m<DCF = 138°

6. See picture below.

7. <AGE, <BEG, <CHG, <DHF

8. If m<AGE = 85°, what is m<CHG?

Answer: Angles AGE and CHG are corresponding angles, so they are congruent.

m<CHG = 85°

The point on the circle that corresponds to the angle will be:

From the complete question, the point on the circle that best corresponds to the angle is illustrated above.

Also, the least positive angle that is coterminal with 747° will be:

= 747 - 720

= 27°

The least positive angle that is coterminal with 1074° will be:

= 1074 - 720

= 354°

Step-by-step explanation:

[tex]\cos(\frac{3 \pi}{2}-\theta)=\cos(\frac{3 \pi}{2})\cos(\theta)+\sin(\frac{3 \pi}{2})\sin(\theta)[/tex]

[tex]\textsf{As }\cos(\frac{3 \pi}{2})=0\textsf{ and }\sin(\frac{3 \pi}{2})=-1[/tex]

Answer:

1) x = y + 4

2) x + 6 = y

3) x = 2y

Answer:

1.  y = x - 4

2. y = x + 6

3. y = (1/2)x

4. c = 1.55n

5. e = 7.75h

 25 hours

Step-by-step explanation:

1.  y = x - 4

2. y = x + 6

3. slope m = change in y ÷ change in x

⇒ m = (7 - 6) ÷ (14 - 12) = 1/2

⇒ y - 6 = 1/2(x - 12)

⇒ y = (1/2)x

4. let c = cost

   let n = number of songs

Ordered pairs:  (1, 1.55) (2, 3.10) (5, 7.75)

⇒ c = 1.55n

5. let h = hours worked

  let e = total earnings

earns $7.75 per hours

⇒ e = 7.75h

video game system = $193.75

⇒ 193.75 = 7.75h

⇒ h = 25

Answer:

1963.2 pounds (lbs.)

Step-by-step explanation:

Things to understand before solving:

The Z-score reflects how far the measure deviates from the mean. After determining the Z-score, we examine the z-score table to determine the p-value associated with this z-score. This p-value represents the likelihood that the measure's value is less than X, or the percentile of X. Subtracting 1 from the p-value yields the likelihood that the measure's value is larger than X.

As long as n is more than 30, the Central Limit Theorem may be applied to a skewed variable. A specific kind of steel cable has an average breaking strength of 2000 pounds, with a standard variation of 100 pounds.

This means, ц  = 2000 and б = 100.

A random sample of 20 cables is chosen and tested.

This means that n = 20, [tex]s=\frac{100}{\sqrt{120} } =22.361[/tex]

Determine the sample mean that will exclude the top 95 percent of all size 20 samples drawn from the population.

This is the 100-95th percentile, or X when Z has a p-value of 0.05, or X when Z = -1.645. So [tex]Z=\frac{X-u}{a}[/tex]

[tex]Z=\frac{X-u}{a} \\-1.645=\frac{X-2000}{22.361} \\X-2000=-1.645*22.361[/tex]

[tex]X =1963.2[/tex]

The sample mean that will cut off the top 95% of all size 20 samples obtained from the population is 1963.2 pounds.

for year 2 we got 12 sales

Step-by-step explanation:

since the first year Mr.Jackson sold 3 computer monitors then in the second year he must've multiplied the times he had sold it which means 4 x 3 which equals 12

as well as the third year, on the third year he sold 6 times the first year so it means 6 x 3 which equals 18

The ratio after simplify the provided ratio R, 75:25 cents, which is equivalent ratio of this ratio is 3:1.

The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.

When we simplify and write ratio of two number, we get the equivalent ratio of the original ratio.

The equivalent ratio is the ratio which is same in the value as the original ratio, but the numerator and denominator is different for both the ratios.

Here, the given ratio in the problem is 75:25 cents​. It can be written as,

[tex]R_5=\dfrac{75}{25}\\[/tex]

As, the number 25 can divide the number 75 in three times. Thus, the ratio will become after simplifying the given ratio as,

Using the normal distribution and the central limit theorem, it is found that there is a 0.2033 = 20.33% probability that Becky’s proportion of poses held for over a minute is greater than Carla’s.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

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

For each sample, we have that:

[tex]p_B = 0.29, s_B = \sqrt{\frac{0.29(0.71)}{50}} = 0.046[/tex]

[tex]p_C = 0.35, s_C = \sqrt{\frac{0.35(0.65)}{50}} = 0.057[/tex]

For the distribution of the difference of the proportions of Becky and Carla, we have that:

[tex]\mu = p_B - p_C = 0.29 - 0.35 = 0.06[/tex]

[tex]s = \sqrt{s_B^2 + s_C^2} = \sqrt{0.046^2 + 0.057^2} = 0.073[/tex]

The probability that Becky’s proportion of poses held for over a minute is greater than Carla’s is the probability that the subtraction is above 0, that is, 1 subtracted by the p-value of Z when X = 0, hence:

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

By the Central Limit Theorem

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

[tex]Z = \frac{0 + 0.06}{0.073}[/tex]

[tex]Z = 0.82[/tex]

[tex]Z = 0.82[/tex] has a p-value of 0.7967.

1 - 0.7967 = 0.2033.

0.2033 = 20.33% probability that Becky’s proportion of poses held for over a minute is greater than Carla’s.
