Which is a parallelogram? For points A B C D

Answer:

x=-1

Step-by-step explanation:

Using the normal approximation to the binomial, the probabilities are given by:

a) 0.8485 = 84.85%.

b) 0.0244 = 2.44%.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we have that:

The mean and the standard deviation of the approximation are given, respectively, by:

[tex]\mu = np = 600(0.05) = 30[/tex]

[tex]\sigma = \sqrt{np(1-p)} = \sqrt{600(0.05)(0.95)} = 5.3385[/tex]

Item a:

Using continuity correction, the probability is P(X > 24.5), which is one subtracted by the p-value of Z when X = 24.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{24.5 - 30}{5.3385}[/tex]

[tex]Z = -1.03[/tex]

[tex]Z = -1.03[/tex] has a p-value of 0.1515.

1 - 0.1515 = 0.8485.

0.8485 = 84.85% probability.

Item b:

This probability is P(X < 19.5), which is the p-value of Z when X = 19.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{19.5 - 30}{5.3385}[/tex]

[tex]Z = -1.97[/tex]

[tex]Z = -1.97[/tex] has a p-value of 0.0244.

The probability is of 0.0244 = 2.44%.

Hey there!

To find the number that's one-fourth of 360, we should just divide 360 by 4 and get 90.

There's also another way - multiplying fractions.

[tex]\bold{\displaystyle\frac{1}{4} *\frac{360}{1}}[/tex]

In order to multiply fractions, we just multiply the numerator of one fraction times the numerator of the other one; same with the denominator.

Look what happens when I multiply:

[tex]\bold{\displaystyle\frac{360}{4}}[/tex]

We can use mental maths to solve it.

Hence, the answer's 90.

Hope everything is clear.

Let me know if you have any questions!

Answer:

The probability is [tex]P(X \le 0.60) = 0.000 [/tex]

Step-by-step explanation:

From the question we are told that

   The overall pass rate is  [tex]R  =  76\% =  0.76[/tex]

   The sample size is  n  =  400

   The percentage that passed is  [tex]k =  60\%  =  0.60[/tex]

Generally the standard error is mathematically represented as

     [tex]\sigma _{\= x } =  \sqrt{\frac{R (1 -R)}{n} }[/tex]    

  =>    [tex]\sigma _{\= x } =  \sqrt{\frac{0.76 (1 -0.76)}{400} }[/tex]

  =>    [tex]\sigma _{\= x } = 0.0214 [/tex]  

Generally the probability of a simple random sample of 400 having a pass rate of 60% or less is mathematically represented as

      [tex]P(X \le 0.60) = P(\frac{X - R}{ \sigma_{\= x}}  \le \frac{0.60 - 0.76}{0.0214} )[/tex]

=>   [tex]P(X \le 0.60) = P(Z \le -7.48 )[/tex]

Generally from the z-table  

      [tex]P(Z \le -7.48 ) =  0.000[/tex]

So

  [tex]P(X \le 0.60) = 0.000 [/tex]

Answer:

5

Step-by-step explanation:

The square root of 29.16 is approximately 5.4. Therefore, the square root of √ 3⁶/²⁵ is approximately 5.4.

The square root of a number is a value that, when multiplied by itself, gives the original number.

To find the square root of √ 3⁶/²⁵, we can break it down into simpler steps.

Step 1: Simplify the expression inside the square root. √ 3⁶/²⁵ can be simplified as follows: √(3⁶ / 5²)

Step 2: Simplify the numerator and the denominator separately.

The numerator is 3 raised to the power of 6, which means multiplying 3 by itself six times:

[tex]3^6[/tex] = 3 × 3 × 3 × 3 × 3 × 3 = 729

The denominator is 5 raised to the power of 2, which means multiplying 5 by itself two times: [tex]5^2[/tex] = 5 × 5 = 25

So, the expression becomes: √(729 / 25)

Step 3: Simplify the expression inside the square root.

√(729 / 25) = √(29.16)

Step 4: Find the square root.

The square root of 29.16 is approximately 5.4. Therefore, the square root of √ 3⁶/²⁵ is approximately 5.4.

Answer:

11/6

Step-by-step explanation:

2x/3 = 1/2

Cross multiply, get 4x = 3, x = 3/4

3y/4 = 3/2

Cross multiply, get 6y = 12, y = 2

x + y = 3/4 + 2 = 11/4

xy = 3/4 * 2 = 3/2

(x + y)/(xy) = (11/4)/(3/2) = 11/4 * 2/3 = 22/12 = 11/6

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The term range is used when looking for y.

This automatically eliminates the possibility of B and D.

Since y applies only to the vertical aspect of the graph, we can ignore all of the horizontal information (time minutes)

Looking at distance, the bug's lowest point was at 100cm and at its highest point at 400cm

This means the minimum is 100 and maximum is 400

In other words:

100 <= y <= 400

Answer:

C) 100 ≤ y ≤ 400

When we are talking about range, we are talking about y values, so B is disqualified.

When determining range you want the lowest & highest y values.

On this graph the lowest value of y is 100 (seen between 5 and 6 seconds).

The highest value of y is 400 (seen at 8 seconds).

Therefore, 100 ≤ y ≤ 400.

Answer:

x = 67; y = 121; z = 65

Step-by-step explanation:

x + 1 + 112 = 180

x + 113 = 180

x = 67

y - 9 = 112

y = 121

z + 3 + 112 = 180

z + 115 = 180

z = 65

I agree with cristafers work

Step-by-step explanation:

The new coordinates of S' will be located at (1, 8)  after translating 4 units right and 2 units down.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.

For example, If shift up by 1 unit,  add 1 to the function

If shift down by 4 units, subtract 4 from the function

Given that Δ RTS has a vertices R (10,0) S (3,4) And T(4,2)

The original coordinate of S is (3,4).

To determine the image of S' after a vertical transition two units down and a horizontal transition of four units to the right

The y-coordinate will increase by 4 if we move it to the right.

This will then become 4+4 =8.

If we shift it downward, it will become negative and read as -2.

This will then become 3-2 = 1.

So, the coordinate of S' will be located at (1, 8)

Hence, the new coordinates of S' will be located at (1, 8)  after translating 4 units right and 2 units down.

Hi!

These can be set up as systems of equations.

Let b = the number of birds, and let d = the number of dogs.

b + d = 21

2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)

You can solve this using either elimination or substitution.
