Actually Welcome to the Concept of the straight lines.

y-y1 = m(x-x1) + C

====> y - 1 = 3(x - 2)

====> y-1 = 3x -6

====> y = 3x - 5

hence the equation is y = 3x - 5

Answer:

m∡A = 100°

m∡B = 50°

m∡C = 30°

Step-by-step explanation:

let 'x' = m∡B;  50°

let '2x' = m∡A;   100°

let 'x-20' = m∡C;   30°

x + 2x + x - 20 = 180

4x - 20 = 180

4x = 200

x = 50

Step-by-step explanation:

Given:

A plane is normal to the vector = -2i+5j+k

It contains the point (-10,7,5).​

To find:

The component equation of the plane.

Solution:

The equation of plane is

[tex]a(x-x_0)+b(y-y_0)+c(z-z_0)=0[/tex]

Where, [tex](x_0,y_0,z_0)[/tex] is the point on the plane and [tex]\left< a,b,c\right>[/tex] is normal vector.

Normal vector is -2i+5j+k and plane passes through (-10,7,5). So, the equation of the plane is

[tex]-2(x-(-10))+5(y-7)+1(z-5)=0[/tex]

[tex]-2(x+10)+5y-35+z-5=0[/tex]

[tex]-2x-20+5y-35+z-5=0[/tex]

[tex]-2x+5y+z-60=0[/tex]

[tex]-2x+5y+z=60[/tex]

Therefore, the equation of the plane is [tex]-2x+5y+z=60[/tex].

Answer:

1/36 = 0.0278 = 2.78% probability that you guess the summer's top two must see movies if you randomly guess

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the movies are chosen is not important, which means that we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Desired outcomes:

Top two movies, so only one outcome, which means that [tex]D = 1[/tex]

Total outcomes:

Two movies from a set of 1. So

[tex]T = C_{9,2} = \frac{9!}{2!(9-2)!} = 36[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{1}{36} = 0.0278[/tex]

1/36 = 0.0278 = 2.78% probability that you guess the summer's top two must see movies if you randomly guess

Answer:

1.39%

Step-by-step explanation:

This is a permutation problem because order matters.

There are 9! ways to rank the summer's must-see movies.

There are (9−2)!=7! ways to choose two movies as the top two must-see movies.

P = 7!/9! = 1/72 = 0.0139

To express our answer as a percent, we multiply by 100:

0.0139 x 100 = 1.39%

Answer:

1) x<2.5 2) x<2.5 (both are smaller numbers than 2.5)

Step-by-step explanation:

I'm sure there is a easier way to figure this question out but how I did is by simply imputing numbers smaller or bigger into where the x is. For example, I imputed 3 into -4x+5>-5. So, -4(3)+5>5, = -7>5, this is false, so x must be smaller than 2.5 in order for this to be true.

Answer:

y = 5x + (anything except negative 10)

For example:

y = 5x + 5

Step-by-step explanation:

A parallel equation is any equation with the same slope, but a different y intercept. As long as your y intercept isn't - 10, your answer will be parallel.

Step-by-step explanation:

A (-3 , 4) and C ( 2 , -6 ) and ratio of AB : AC is 4:5

now , let AB be 4x and AC be 5x such that

AC = AB + BC

AC - AB = BC

5x - 4x = BC

x = BC

ratio of AB : BC = 4:1

by using section formula

( mx2 + nx1 / m+n , my2 + ny1 / m+n )

where m = 4 and n = 1

B = ( 4×2 + 1×-3 / 4+1. ,. 4× -6. + 1× 4 / 4+1 )

B = ( 8 -3 / 5. ,. -24 + 4 / 5)

B = ( 5/5. ,. -20/5 )

B = ( 1. , -4 )

Answer: -3

Step-by-step explanation:

-8x - 5y = -1

Answer:

a/..the first is 3/8

b/ 84/280

Answer:

a) 3/8

b) 3/10

Step-by-step explanation:

multiply the numerators and the denominators and then simplify.

a) is just 3*1 divided by 4*2, no simplification possible

b) is 4*21 divided by 7*40 is 84/280 and simplifies to 3/10 (divide by 28)

Answer:

D

Step-by-step explanation:

Because, the biologist wants to find the difference between the population of trouts from two watershed,

A biologist wants to compare the proportions of rainbow trout infected with whirling disease (an illness of trout and salmon caused by a microscopic parasite) coming from two separate watersheds.

The biologist will collect a random sample of trout and record the proportion infected in the sample The biologist intends to estimate the difference for all trout in the two watersheds

According to the given question, the most appropriate method for the biologist will be -A two-sample z-interval for a difference in population proportions

Because,Biologist wants to compare the proportions of rainbow trout infected with whirling disease and find the difference between the population of the trouts from two watershed .

Therefore , Statement D is the Correct

Answer:

P(9,7) =  181440

Step-by-step explanation:

The roles are distinct so order matters. So we must use the permutation formula.

P(n,r)=n!/(n−r)!

P(9,7) = 9! / 2! = 9*8*7*6*5*4*3 = 181440

Answer:

P = 150 - 25w

Step-by-step explanation:

Amount borrowed = $150

Repayment amount = $25 each week

P = amount Nancy owes

w = number of weeks

Amount Nancy owes = amount borrowed - repayment plan per week

P = 150 - 25w

During the first week of repayment: when w = 1

P = 150 - 25w

P = 150 - 25(1)

= 150 - 25

= 125

P = $125

Step-by-step explanation:

Credit card interest is what are you are charged when you don't pay your credit card bill in full each month. It works as a daily rate calculated by dividing your annual percentage rate by 365, and then multiplying your current balance by the daily rate. That amount is then added to your bill.

The surface area of a cube is calculated using the following formula

[tex]S=6a^2[/tex]

If the surface area is given then the side length can be found and vice versa.

We have thus

Answer:

137.67

Step-by-step explanation:

hello !

first, we find the midpoint of each interval in the score column (you can look for it by adding the two numbers and then dividing it by 2). then, we multiply the midpoint to the frequency:

1 - 7 is 4 = 4 * 17 = 68

8 - 10 is 9 = 9 * 15 = 135

11 - 15 is 13 = 13 * 13 = 169

16 - 20 is 18 = 18 * 6 = 108

23 - 35 is 29 = 29 * 6 = 174

36 - 50 is 43 = 43 * 4 = 172

now, we look for the mean, which we get by adding the sums and dividing the total with 6.

[tex]\frac{68+135+169+108+174+172}{6} = 137.6666667[/tex] or, when rounded to two decimal places, is equal to 137.67.

Answer:

20%

Step-by-step explanation:

Not sure if this is exactly correct, but let's say we start with 1 unit. If it increased by 25%, we get:

1 × 1.25 = 1.25 units.

Now, to get back to 1 unit, we need to find:

1.25 × ?  = 1

? = [tex]\frac{1}{1.25}[/tex] = 0.80

So, 100% - 80 % = 20%

A 20% decrease.

Not completely sure though.
