Find YZ.


Geometry, circles.​

Answers

Answer:

YZ = 44

Step-by-step explanation:

(2x - 6) × 21 = (x + 1) × 30 => intersecting chords theorem

42x - 126 = 30x + 30

Collect like terms

42x - 30x = 126 + 30

12x = 156

12x/12 = 156/12

x = 13

✔️Find YZ:

YZ = 30 + x + 1

Plug in the value of x

YZ = 30 + 13 + 1

YZ = 44

The dimensions of an iPhone are x – 2 and x + 3. If the area of an iPhone is 14 square inches, find the dimensions of the iPhone

Answers

Answer:

The dimensions of the iphone are 2 inches by 7 inches.

Step-by-step explanation:

Given that,

The dimensions of an iPhone are x – 2 and x + 3.

The area of an iphone is 14 sq inches

We need to find the dimensions of the iPhone. It is in the shape of a rectangle. Its area is given by :

[tex]A=l\times b\\\\(x-2)(x+3)=14\\\\x^2-2x+3x-6=14\\\\x^2+x-6-14=0\\\\x^2+x-20=0\\\\x^2+5x-4x-20=0\\\\x(x+5)-4(x+5)=0\\\\(x-4)(x+5)=0\\\\x=4\ and\ x=-5[/tex]

Neglecting negative value

First dimension = (x-2) = (4-2) = 2 inches

Other dimension = (x+3) = (4+3) = 7 inches

Hence, the dimensions of the iphone are 2 inches by 7 inches.

Past experience indicates that the time required for high school seniors to complete a standardized test is a normal random variable with a standard deviation of minutes. Test the hypothesis that against the alternative that if a random sample of the test times of high school seniors has a standard deviation . Use a level of significance.

Answers

Complete question :

Past experience indicates that the time required for high school seniors to complete a standardized test is a normal random variable with a mean of 35 minutes. If a random sample of 20 high school seniors took an average of 33.1 minutes to complete this test with a standard deviation of 4.3 minutes, test the hypothesis, at the 0.05 level of significance.

Answer:

We conclude they there is significant evidence to support the claim That time required for high school seniors to complete test is less than 35 minutes.

Step-by-step explanation:

H0 : μ = 35

H1 : μ < 35

Sample size, n = 20

Standard deviation, s = 4.3

xbar = 33.1

Test statistic :

T = (xbar - μ) ÷ (s /√n)

T = (33.1 - 35) ÷ (4.3 /√20)

T = - 1.9 ÷ 0.9615092

T = - 1.976

The Pvalue can be obtained from the test statistic using a Pvalue calculator :

Pvalue at 0.05 ; df = 19 is 0.0314

Since, Pvalue < α ; We reject the Null and conclude that time required for high school candidate to complete test is less than 35 minutes

A red line and a blue line bus both left the stadium at 4:00 p.m.

Red line buses were scheduled to leave the stadium every 6 minutes.

Blue line buses were scheduled to leave the stadium every 8 minutes.

if the buses run on schedule, when is the next time a red line and a Blue line bus will leave together?

Answers

Answer:

4:24pm

Step-by-step explanation:

To answer this question, we need to find the LCM (Lowest common multiple) of 6 and 8 to find out when they will leave at the same time again.

To do this we can either list all the prime factors of each one and multiply the non-common ones:

6 = 2x3

8 = 2x2x2

2x2x3 = 24

OR we can list the multiples and find the lowest matching ones:

6 => 6, 12, 18, 24, 30

8 => 8, 16, 24, 32, 40

We can see that 24 is the least common factor.

This means that both busses will leave at the same time 24 minutes after 4pm.

Therefore the next time a red line and blue line bus will leave together is 4:24pm.

Answers

Answer:

<D = 147 degrees

AB = 14

BC = 12

Step-by-step explanation:

From the given parallelogram;

<A and <D are supplementary, hence;

<A + <D = 180

33 + <D = 180

<D = 180 - 33

<D = 147 degrees

Since AB = CD

Hence AB = 14

Also since BC = AD, BC = 12

This shows that the opposite side of the parallelogram are parallel

Use Green's Theorem to evaluate the line integral along the given positively oriented curve.

∫ c(y+e√x)dx+(2x+cosy2)dy,

C is the boundary of the region enclosed by the parabolas

y=x^2 and x=y^2

Answers

Answer:

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy = 1/3

Step-by-step explanation: See Annex

Green Theorem establishes:

∫C ( Mdx  +  Ndy )  = ∫∫R ( δN/dx  -  δM/dy ) dA

Then

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy

Here

M = 2x  + cosy²           δM/dy  =  1

N = y + e√x                 δN/dx  =  2

δN/dx  -  δM/dy  =  2  -  1   = 1

∫∫(R) dxdy   ∫∫ dxdy

Now integration limits  ( see Annex)

dy  is from   x  = y²    then     y = √x    to  y = x²   and for dx

dx   is from 0   to  1 then

∫ dy    = y | √x   ;   x²      ∫dy    =  x² - √x

And

∫₀¹ ( x² - √x ) dx    =  x³/3  - 2/3 √x |₀¹    =   1/3 - 0

∫ C ( y + e√x) dx  +  ( 2x + cosy² ) dy = 1/3

Flip a fair coin 6 times. Let X be the number of heads in the rst 4 ips, and Y be the number of heads on the last 4 ips. Find Cov(X; Y ).

Answers

Answer:

Cov ( X, Y ) = 1/2

Step-by-step explanation:

X = Number of heads in the first 4 flips

Y = Number of heads in the last 4 flips

Given that X and Y are binomial variables hence

P( probability ) = 1/2

Find Cov( X; Y )

xi = result of the ith flip ∴ X = x1 + x2 + x3 + x4

yj = result of the  jth flip ∴ Y = y3 + y4 + y5 + y6

covariance of  xi and yi = 1/2 * 1/2 = 1/4   when i = j  and it is = 0 when i ≠ j

hence Cov( X; Y ) can be expressed as

Cov( X; Y ) = ∑[tex]_{i}[/tex]^4 ∑[tex]_{j}[/tex]^6 ∴ Cov( Xi , Yj ) = 2/4 = 1/2  (  given that i = j )
