Answer:

49

Step-by-step explanation:

By the definition of slope, as vertical change over horizontal change, we get

[tex]-4=m = \frac{\Delta y }{\Delta x} = \frac{r-1}{-6-6} = -\frac{r-1}{12}[/tex]

By checking the first and the last step of that chain

[tex]-4=-\frac {r-1}{12} \rightarrow r-1=48\rightarrow r= 49[/tex]

Answer:

[tex]\displaystyle 7x + 9y = 45[/tex]

Step-by-step explanation:

y = –⁷⁄₉x + 5

+ ⁷⁄₉x + ⁷⁄₉x

___________

⁷⁄₉x + y = 5 [We CANNOT leave the equation like this, so multiply by 9 to eradicate the fraction.]

9[⁷⁄₉x + y = 5]

Answer:

10% to decimal is equal to 0.1.

Therefore 20 x 0.1 = 2

Step-by-step explanation:

Each window is independently probable for having minor defects. The expected number of window frames having minor defects = 2.

Other figures are:

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as

[tex]X \sim B(n,p)[/tex]

The probability that out of n trials, there'd be x successes is given by

[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]

The expected value and variance of X are:

For the considered case, we can assume that each window is independent of each other for having defects or being perfect.

Each window can be having defects (call it success) or no defects(call it failure).

Then, we can take:

X =  number of windows out of 20 windows being perfect (no defect).

Then we get:

Evaluating each sub parts one by one:

Expect number of defective windows = E(X) = np = 20 × 0.1 = 2

Standard deviation is the positive root of variance.

Standard deviation of number of windows (out of 20 windows of sample) having defects = [tex]\sqrt{Var(X)} = \sqrt{np(1-p)} = \sqrt{2(0.9)} \approx 1.34[/tex]

P(X = 2) = [tex]^{20}C_2(0.1)^2(0.9)^{18} \approx 0.285[/tex]

P(X > 3) = 1 - P(X ≤ 3)

[tex]P(X > 3) = 1 -[ P(X = 0) + P(X = 1) +P(X= 2)+ P(X = 3)]\\\\P(X > 3) = 1- [^{20}C_0(0.1)^0(0.9)^{20} +^{20}C_1(0.1)^1(0.9)^{19} +\\\: \:\: ^{20}C_2(0.1)^2(0.9)^{18} +^{20}C_3(0.1)^3(0.9)^{17} ]\\\\P(X > 3) \approx 1-[ 0.1216 + 0.2702 + 0.2852 + 0.1901]=1-0.8671=0.1329 \\\\P(X > 3) \approx 0.1329[/tex]

Answer:

Step-by-step explanation:

Slope intercept form is y = mx + b where m is the slope and b is the y intercept.

We are given m = 1/2

Plug the point (-4,-5) in for x and y and the given slope in for m.

y = mx + b

-5 = 1/2(-4) + b

Now solve for b.

-5 = -2 + b

b = -3

Now plug m and b back in to get your slope intercept form.

y = 1/2x -3

Answer:

[tex]y=6(x-8)-2\qquad\text{point-slope form}[/tex]

[tex]y=6x-50\qquad\text{slope-intercept form}[/tex]

Step-by-step explanation:

The equation of a line can be written in several forms. Two of the most-used forms are the point-slope and the slope-intercept forms.

The point-slope form requires to have one point (xo, yo) through which the line passes and the slope m. The equation expressed in this form is:

[tex]y=m(x-xo)+yo[/tex]

The slope-intercept form requires to have the slope m and the y-intercept b, or the y-coordinate of the point where the line crosses the y-axis. The equation is:

[tex]y=mx+b[/tex]

The line considered in the question has a slope m=6 and passes through the point (8,-2). These data is enough to find the point-slope form of the line:

[tex]\boxed{y=6(x-8)-2\qquad\text{point-slope form}}[/tex]

To find the slope-intercept form, we operate the above equation:

[tex]y=6x-48-2[/tex]

[tex]\boxed{y=6x-50\qquad\text{slope-intercept form}}[/tex]

Answer:

20 cm³

Step-by-step explanation:

Since the volume of a cylinder is 60 cm³, which we can express it as:

[tex]\displaystyle \large{\pi r^2 h=60}[/tex]

Keep in mind that [tex]\displaystyle \large{\pi r^2 h}[/tex] is the cylinder’s volume formula, and we want to find the volume of a cone with same radius and height. When they say same radius and height, they mean that the radius and height are the same as cylinders’.

But since no values of radius and height are given, we know that the volume of a cone is:

[tex]\displaystyle \large{\frac{1}{3}\pi r^2 h}[/tex]

Compare both formulas:

[tex]\displaystyle \large{\pi r^2h}[/tex] — cylinder’s volume

[tex]\displaystyle \large{\frac{1}{3}\pi r^2h}[/tex] — cone’s volume

See how they are quite similar except that cone’s volume has 1/3. That means cone’s volume is 1/3 of cylinder’s volume

Finding cone’s volume, multiply both sides by 1/3:

[tex]\displaystyle \large{\pi r^2h=60}\\\displaystyle \large{\frac{1}{3}\pi r^2h=\frac{1}{3}\cdot 60}\\\displaystyle \large{\frac{1}{3}\pi r^2h=20}[/tex]

Therefore, the volume of a cone with same radius and height from cylinder is 20 cm³.

__________________________________________________________

Summary

Volume (Cone) (1/3 of cylinder’s volume):

[tex]\displaystyle \large{V=\frac{1}{3}\pi r^2 h}[/tex]

Volume (Cylinder):

[tex]\displaystyle \large{V=\pi r^2h}[/tex]

They are quite related!

Answer:

What is the question??

Step-by-step explanation:

Hey there!

Let's find the slope & y-intercept of each equation.

The first one is y=4x-5.

Please remember that

In other words, in slope-intercept form (y=mx+b), m is always the slope and b is the y-intercept.

Therefore,  the slope of the first linear equation is 4, and the y-intercept is -5.

or

m=4, b=-5 (option A)

Same with the other equation:

m=-1, b=2/3 (option C is the right option)

Hope everything is clear.

Quizlet fortunately had the same question with this answer, so here you go! :)

Answer:

CD = EC ⇒ proved down

Step-by-step explanation:

If a point lies on a segment, then it divides the segment into two parts, the sum of their length equals the length of the segment

Example:

If point Z lies on the segment XY, then Z divides XY into segments XZ and ZY, where XY = XZ + ZY

Let us use this fact to solve the question

∵ BD and EF intersected at point C

∴ C divides BD into two segments BC and CD

∴ C divides EF into two segments EC and CF

→ By using the fact above

∴ BD = BC + CD

∴ EF = EC + CF

∵ BD = EF ⇒ given

→ Equate their right sides

∴ BC + CD = EC + CF

∵ BC = CF ⇒ given

→ That means their adding segments are equal

∴ CD = EC ⇒ proved

The approximate APR generated when you borrow $1,000 for 5 years at an add-on interest rate of 6%, = $300

Annual percentage rate is defined as the yearly interest generated by a sum that's charged to borrowers.

The formula for APR = p×t×r/100

The principal amount deposited (p)= $1000

Time (t) = 5 years

At the rate (r) = 6%

Therefore APR=

[tex] \frac{p \times t \times r}{100} [/tex]

[tex] \frac{1000 \times 5 \times 6}{100} [/tex]

[tex] \frac{30000}{100} [/tex]

APR = $300

Therefore, the approximate APR = $300

Mr. Fitzgerald = 2b - 15

Mr. Lloyd = 1/2b + 30

Find b:

176 = b + b + 8 + 2b - 15 + 1/2b + 30

176 = 9/2b + 23

153 = 9/2b

b=34
