I need help. Can you help me please.

Answer:

45 minutes or can be also 0.75 hours

Step-by-step explanation:

per hours refers to 1 hours.

40 km ---> 1 hours

1 km ---> 1/40 hours

30 km ---> { ( [tex]\frac{1}{40}[/tex] ) * 30} hours

          --> 0.75 hours

Conversion: 0.75 * 60 minutes

                   : 45 minutes

For x-intercepts, y is zero y = x² - 12x + 32 then x-intercept is (8,0) and (4,0)

For x-intercepts, y is zero y = x² - 10x + 24 then x-intercept is (6,0) and (4,0)

For x-intercepts, y is zero y = x² + 10x + 16 then x-intercept is (-2,0) and (-8,0)

For x-intercepts, y is zero y = x² - 25 then x-intercept is (5,0) and (-5,0)

For x-intercepts, y is zero y = x² + 8x + 12 then x-intercept is (-2,0) and (2,0)

X- intercepts is "x coordinates of a point where a line, a curve or surface intersects at x- axis".

According to the question,

a) y = x² - 12x + 32 (Put y=0)

x² - 12x + 32 = 0

(x-8) (x-4) = 0

x - 8 =0: x - 4 = 0

x = 8 and 4

x - intercept is (8,0) and (4,0)

b) y = x² - 10x + 24 (Put y=0)

x² - 10x + 24= 0

(x-6) (x-4) = 0

x - 6 = 0: x - 4 = 0

x = 6 and 4

x - intercept is (6,0) and (4,0)

c) y = x² + 10x + 16 (Put y=0)

x² + 10x + 16 = 0

(x+2) (x+8) = 0

x + 2=0: x + 8 = 0

x = -2 and -8

x - intercept is (-2,0) and (-8,0)

d) y = x² - 25 (Put y=0)

x² - 25 = 0

x² = 25

x = ± 5

x - intercept is (+5,0) and (-5,0)

e) y = x² + 8x + 12 (Put y=0)

x² + 8x + 12 = 0

(x+2) (x+6) = 0

x + 2=0: x + 6 = 0

x = 2,6

x - intercept is (2,0) and (6,0)

One-Sample Z-Interval Information

Problem 1

As stated previously, Anas should use the critical value [tex]z^*=1.4395[/tex] to construct the 85% confidence interval

Problem 2

Given our formula for the margin of error (MOE), the value is [tex]MOE=\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}=\sqrt{\frac{0.216(1-0.216)}{250}}\approx0.026[/tex]

Problem 3

The 85% confidence interval would be [tex]CI=\hat{p}\pm z^*\biggr(\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\biggr)=CI=0.216\pm 1.4395(0.026)\appro=\{0.1786,0.2534\}[/tex], which means that we are 85% confident that the true proportion of people that clicked on the advertisement is between 0.1786 (~45 people) and 0.2534 (~63 people)

Problem 4

Increasing the sample size to [tex]n=500[/tex] is going to decrease the margin of error because it is a closer representation of the population, but, alas, requires more time, energy, and resources to observe.

-Chetan K

Answer:

m = -3/4; b = -2

Step-by-step explanation:

y = mx + b

First, we use the coordinates of the points to find the slope, m.

m = (y2 - y1)/(x2 - x1) = (-2 - (-5))/(0 - 4) = (-2 + 5)/(-4) = -3/4

The slope, m = -3/4.

Now we use the slope and the coordinates of one point in the equation y = mx + b to find b.

y = mx + b

y = (-3/4)x + b

Let's use point (0, -2).

-2 = (-3/4)(0) + b

b = -2

Answer: m = -3/4; b = -2

Answer:

x = -2.25

Step-by-step explanation:

Answer:

x = -2.25

Step-by-step explanation:

Add 15 to both sides of the equation

-6x - 15 = -1.5

-6x-15+15=-1.5+15

Simplify

-6x = 13.5

Divide both sides of the equation by the same term

-6x/6 = 13.5/6

Simplify

x = -2.25

Answer:

?=4

Step-by-step explanation:

First, we have to tell how we got from 9700 to 0.97. so we know that it is divided by 10^?. When you divide by 10, it is the same as moving the decimal point one space to the left. SO all you have to do is count how many times the decimal point got moved to get from 9700 to 0.97. This number is 4 so the question mark is 4 because 9700/10^4 will move the decimal place 4 to the right and give you 0.97.
