Find an equation of a plane through the point (3, 0, 2) which is orthogonal to the linex=?2+3t,y=2+4t,z=?1?3tin which the coefficient of x is 3.

Answers

Answer 1

Answer: 3x + 4y - 3z - 3 = 0

Step-by-step explanation:

with the given point (3, 0, 2), the plane is orthogonal to this line so it

has directional ratios (3, 4, -3)

therefore the given equation can be written as;

(x+2)/3 = (y-2)/4 = (z+1)/-3

so equation of the plane passing through point x1, y1 and z1 in the one point form is given as;

a(x-x1) + b(y - y1) + c(z -z1) = 0

abc represent the direction ratio

so we substitute

3(x-3) + 4(y-0) + (-3(z-2)) = 0

3x - 9 + 4y - 0 - 3z + 6 = 0

3x + 4y - 3z - 3 = 0

therefore the equation of the plane through the point is  3x + 4y - 3z - 3 = 0

A tree is 4 1/2 feet tall. It is expected to grow 1 3/4 feet per year. At this growth rate, how many years will it take for the tree to have a height greater then 40 feet?

Answers

Answer:

21 years

Step-by-step explanation:

Given

[tex]Initial\ Height = 4\frac{1}{2}[/tex]

[tex]Final\ Height = 40[/tex]

[tex]Difference = 1\frac{3}{4}[/tex]

Required

Determine the years it'll take to grow to the final height

This question depicts arithmetic progression and will be solved using

[tex]T_n = a + (n - 1)d[/tex]

Where

[tex]T_n = 40[/tex]

[tex]a = 4\frac{1}{2}[/tex]

[tex]d = 1\frac{3}{4}[/tex]

Substitute these values in the given formula;

[tex]40 = 4\frac{1}{2} + (n - 1)1\frac{3}{4}[/tex]

Convert all fractions to decimal

[tex]40 = 4.5 + (n - 1) * 1.75[/tex]

Open Brackets

[tex]40 = 4.5 + 1.75n - 1.75[/tex]

Collect Like Terms

[tex]1.75n = 40 - 4.5 + 1.75[/tex]

[tex]1.75n = 37.25[/tex]

Divide both sides by 1.75

[tex]n = \frac{37.25}{1.75}[/tex]

[tex]n = 21.2857142857[/tex]

[tex]n = 21[/tex] (Approximated)

The number of years it will take for the tree to have a height greater than 40 feet is 23 years

Given:

Height of the tree = 4 1/2 feet

Growth rate per year = 1 3/4 feet

Expected growth rate = 40 feet

Expected Number of years = y

The inequality:

4 1/2 + 1 3/4y > 40

Subtract 4 1/2 from both sides

1 3/4y > 40 - 4 1/2

7/4y > 40 - 9/2

7/4y > (80-9)/ 2

7/4y > 79/2

divide both sides by 7/4

y > 79/2 ÷ 7/4

y > 79/2 × 4/7

y > (79×4) ) (2×7)

y > (316) / 14

y > 22.57142857142857

Approximately,

y > 23 years

Therefore, number of years it will take for the tree to have a height greater than 40 feet is 23 years

What is subtraction on number line?

Subtraction on a number line helps to subtract smaller numbers very easily. While subtracting numbers on a number line, we need to jump (move) towards the left-hand side of a number line. We always start with the minuend and move towards the left according to the number given as the subtrahend. 'Minuend' is the number from which we subtract and 'subtrahend' is the number which is subtracted.

According to the given question.

We have an expression -8 -3

For evaluating the given expression on number line Michael have to follow some following steps:

Step1: Michael have to locate -8 on the number line.

Step2: Michael have to move towards the left hand side of the number line according to the number given in the subtrahend. In the given expression the subtrahend is 3, so we will move 3 units left. And at -11 he have to stop.

So, -11 will be the answer of the even expression.

Hence, the step which complete evaluate Michael expression is "Michael could rewrite the expression as negative 8 + negative 3 and move 3 spaces to the left".

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p: n = 195, x = 162; 95% confidence.a. 0.788 < p < 0.873.
b. 0.789 < p < 0.873.
c. 0.778 < p < 0.883.
d. 0.777 < p < 0.884.

Answers

Answer:

c. 0.778 < p < 0.883.

Step-by-step explanation:

The formula for confidence interval for proportion =

p ± z score × √p(1 - p)/n

p = x/n

n = 195, x = 162

z score for 95% confidence Interval = 1.96

p = 162/195

p = 0.8307692308

p ≈ approximately equal to = 0.8308

0.8308 ± 1.96 × √0.8308 × (1 - 0.8308)/195

0.8308 ± 1.96 ×√0.8308 × 0.1692/195

0.8308 ± 1.96 × √0.0007208788

0.8308 ± 1.96 × 0.0268491862

0.8308 ± 0.052624405

Confidence Interval

= 0.8308 - 0.052624405

= 0.778175595

Approximately = 0.778

= 0.8308 + 0.052624405

= 0.883424405

Approximately = p

0.883

Therefore, the confidence interval for this proportion = (0.778, 0.883) or option c. 0.778 < p < 0.883

In order to find the zeros of f(x)=x2−8x+12, Jessica needs to first factor the quadratic function. Which of the following is the factored form of the function?

Answers

I’m pretty sure you meant x^2 so I’m going to answer based off that. Change the equation to look like this:

x^2-8x+12=0

Then you factor it. So it would turn into:
(x-6) (x-2) = 0

To solve for zeros, you just put the opposite of the number. In this case, since we have (x-6) the zero here would be positive 6 and for the (x-2), the zero would be positive 2. This is because if you put x-6 = 0 and solved for x, you would add 6 to each side making it a positive 6. The same applies for the (x-2).

                                  ∑ 259                  ∑ 7515

Mean= X`= ∑x/n= 259/10= 25.9

Variance = s²= 1/n-1[∑X²- (∑x)²/n]

= 1/0[7515- (259)²/10]= 1/9[7515- 6708.1]

= 806.9/9=89.655= 89.66

Standard Deviation= √89.655= 9.4687

Hence

The value of t with significance level alpha= 0.05 and 9 degrees of freedom  is t(0.025,9)= 2.262

The 95 % Confidence interval is given by

x`±t(∝,n-1) s/√n

So Putting the values

25.9± 2.262( 9.4687/√10)

= 25.9 ±2.262 (2.9943)

= 25.9 ± 6.7730

= 25.9 +6.7730=32.6730

25.9 -6.7730= 19.1269

= 19.1269, 32.6730

The 95 percent confidence interval for the mean of the population from which the study subjects may be presumed to have been drawn is (19.1269, 32.6730).

If the patient is less than 70 years old, the loading dose is 80 Howell Units2 per kilogram of DM. One Howell Unit is equivalent to 0.0020 mg of pure heparin. 2. Calculate how many mg of pure heparin is in 80 Howell Units. Do not worry about the kilograms of DM yet. 00.1600mg The loading dose, in mg of heparin for a 5-year-old with a total body weight of 40 lbs., with 10% bodyfat (that is, 90% of that 40 lbs. is lean body mass). You may also be interested to know that 1 kg = 2.20 lbs. Think about the steps you need to go through to find the correct dose. Remember, first you need to find the dosing mass....

Answers

Answer:

1) 0.16 mg of pure heparin is in 80 Howell units

2) the loading dose, in mg of heparin for the 5-year-old boy is 2.618 mg

Step-by-step explanation:

Given that;

if a patient is less than 70 years of age then loading dose is 80 Howell units square per Kg of DM,

One Howell unit is equivalent to 0.0020 mg of pure heparin

1)

how many mg of pure heparin is in 80 Howell units.

that will be;

80 × 0.0020 = 0.16 mg

therefore 0.16 mg of pure heparin is in 80 Howell units

2)    

First we find the dosing mass

so dosing mass = body weight of the 5year old boy × 90%

from the question his total body weight of 40 lbs and  1 kg = 2.20 lbs

so

dosing mass = 40lbs × 1kg/2.20lbs × 90/100

dosing mass(kg) = 16.37 kg

Now to calculate the Loading dose we say;

Loading dose = dosing mass × heparin required per kg

Loading dose = 16.36 kg × 0.16 mg heparin per 1kg

loading dose = 2.618 mg heparin

therefore the loading dose, in mg of heparin for the 5-year-old boy is 2.618 mg

A study was conducted on the relationship between speeds of cars and gas mileage. The correlation coefficient was 0.45. Later, the researchers found the speedometers read 5 mph too high. Researchers recomputed the coefficient. The new value will be:

Answers

Answer:

0.45

Step-by-step explanation:

The correlation coefficient is used to measure the relationship between how two variables change. In this question, the two variables are cars speed and gas mileage. Since the speedometers were wrong as they were 5 mph too high in a constant manner, then the correlation between how changes in speed affect gas mileage will not be changed.

For example, if we are measuring how an increase of 15 mph decreased gas mileage, we are looking at the change in speed and it is the same if we start with 75 mph and then increase speed to 90 mph, or if we start with 45 mph and then increase to 60 mph. The change in speed for both cases will remain unchanged at 10 mph.

Now, since we have seen that the change in speed remains unchanged and since correlation coefficient is a measure of the relationship between how two variables change, then the new value of the correlation coefficient will remain the same as 0.45.
