Subtract from the dividend an easy multiple of the divisor

Record the partial quotient in a column to the right of the problem.

Repeat until the dividend has been reduced to zero or the remainder is less than the divisor.

Add the partial quotients to find the quotient.

Which system is represented by the graph

alexandr1967 [171]

Answer:

option A. 3x - y = 2 and 3x - y = 1

Step-by-step explanation:

Using the rule of y-intercept which is the value of y when x equals 0

Option A: 3x-y=2 and 3x-y=1

y-intercepts will be ⇒ -2 and -1

Option B: 3x+y=2 and 3x-y=1

y-intercepts will be ⇒ 2 and -1

Option C: 3x-y=2 and 3x+y=1

y-intercepts will be ⇒ -2 and 1

Option D: 3x+y=2 and 3x+y=1

y-intercepts will be ⇒ 2 and 1

Comparing the results with the y-intercepts from the graph

From the graph the system of equation intersects with y-axis, (which mean x=0), at y = -2 , -1

So, the system which is represented by the graph is option A

A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greate

suter [353]

Answer:

x ≥ 36 miles per hour

Step-by-step explanation:

The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.

Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:

x ≥ 110 miles per hour - 74 miles per hour

x ≥ 36 miles per hour

This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.

Find x, if 1/4 of x is 15

Yuliya22 [10]

Answer:

x = 60

Step-by-step explanation:

Given

$\frac{1}{4}$ x = 15

Multiply both sides by 4 to clear the fraction

x = 4 × 15 = 60

Aleks [24]

Answer:

CI for 90% = ( 16.34, 18.66)

Therefore at 90% confidence interval (a,b) = ( 16.34, 18.66)

And,

CI for 95% = ( 16.11, 18.89)

Therefore at 95% confidence interval (a,b) = ( 16.11, 18.89)

Step-by-step explanation:

Answer: = ( 2.64, 3.14)

Therefore at 95% confidence interval (a,b) = ( 2.64, 3.14)

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

Given that;

Mean x = 17.5

Standard deviation r = 5.7

Number of samples n = 65

Confidence interval = 90% and 95%

z(at 90% confidence) = 1.645

z(at 95% confidence) = 1.96

Substituting the values we have; for 90%

17.5+/-1.645(5.7/√65)

17.5+/-1.645(0.707)

17.5 +/- 1.16

= ( 16.34, 18.66)

Therefore at 90% confidence interval (a,b) = ( 16.34, 18.66)

Substituting the values we have; for 95%

17.5+/-1.96(5.7/√65)

17.5+/-1.96(0.707)

17.5 +/- 1.39

= ( 16.11, 18.89)

Therefore at 95% confidence interval (a,b) = ( 16.11, 18.89)
