Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\for\ a \ sample(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\where\ x=raw\ score,\mu=mean, \sigma=standard deviation[/tex]

Given that n = 49, μ = 260 mg/dL, σ = 35 mg/dL

a) For x < 210:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{210-260}{35/\sqrt{49} } =-10[/tex]

From the normal distribution table, P(x < 210) = P(z < -10) = 0.0001

b) For x > 205:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{205-260}{35/\sqrt{49} } =-11[/tex]

For x < 215:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{215-260}{35/\sqrt{49} } =-9[/tex]

P(205 < x < 215) = P(-11 < z < -9) = P(z < -9) - P(z < -11) = 0.0001 - 0.00001 = 0.00009

c) For x < 200:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{200-260}{35/\sqrt{49} } =-12[/tex]

From the normal distribution table, P(x < 200) = P(z < -12) = 0.00001

d) For x > 222:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{222-260}{35/\sqrt{49} } =-7.6[/tex]

From the normal distribution table, P(x > 200) = 1 - P(z < -12) = 1 - 0.0001 = 0.9999

Answer:

t = 30

Step-by-step explanation:

Step 1: Solve

Use reverse operations to solve

[tex]6=\frac{t}{5}\\6(5)=\frac{t}{5}(5) \\t=30[/tex]

Step 2: Therefore statement

Therefore t is equal to 30

Answer: 2/12 --> 1/6

3/2 --> 1 1/2

Step-by-step explanation:

2/12 can be simplified by dividing the top by 2 and the bottom by two. 2 is the GCF (greatest common factor) of both 2 and 12.

3/2 is a improper fraction so you have to make it a proper fraction. To do that you get 1 and 1/2.  <-- this is for simplest form.

Answer:

2(2−1)

Step-by-step explanation:

4−2

Grouping

Common factor

4−2

2(2−1)

Solution

2(2−1)

To factor, you do the opposite of what you would in distributive property. You have to find the greatest common factor, or GCF, of 4 and -2.

  4                   2

------              -------

1  |  4              1 | 2

2 |  2

So the GCF is 2. Now we factor the expression.

4x-2

2(2x-1)

Answer:

70%

Step-by-step explanation:

Each blue line represents 10%.  Since there are 7 blue lines, we just multiply 10% by 7 and we get 70%

Answer:

70%

Step-by-step explanation:

7 out of 10 rectangles were filled so that's 7/10. 7/10 also equals 70/100. Therefore it's 70 out of 100 or 70%.

Answer:    72

Step-by-step explanation:

[tex] \boxed{ \tt{the \: dimensions \: are : }}\\ \boxed{ \tt{b = 9 \: meters} }\\ \boxed{ \tt{l = 20 \: meters}}[/tex]

[tex]5 {s}^{2} = (3 + s) \times (14 + s) \\ 5 {s}^{2} = {s}^{2} + 17s + 42 \\ {4s}^{2} - 17s - 42 = 0 \\ s = \frac{ - ( - 17) + \sqrt{ {( - 17)}^{2} - 4(4)(42)} }{2(4)} \\ s = \frac{17 + 31}{8} \\ s = 6 \\ hence \to \:the \: dimensions \: are : \\ b = s + 3 = 6 + 3 = 9 \: meters \\ l = s + 14 = 6 + 14 = 20 \: meters[/tex]

The new dimensions of the pool are; Width = 9 and Length = 20.

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

It is given that the square pool was turned into a rectangular one and it's area was enlarged by a factor of 5 by enlarging one side of the pool by 3 meters and the other side by 14.

[tex]5s^2 = (3+s)(14 +s)\\\\5s^2 =s^2+ 17s + 42\\\\4s^2 - 17s - 42 = 0\\\\[/tex]

The root of the expression;

[tex]s = \dfrac{-(-17) + \sqrt{-17^2 - 4(4)(42)} }{2(4)} \\\\s = 6[/tex]

The dimensions are;

Width = 3 + s = 9

Length = 14 + s = 20

If theres no information other than that, then its kinda hard to compute to standard form. However, the website "desmos" and its graphing calculator might help, but im sorry I have to bring you to a link for guidance im in the same unit and just as confused.

Answer:

Hey the answer is 20%.

Step-by-step explanation:

You multiply the $90 with 20%,

but in order to figure that out you need to:

Calculate the savings: 20% of $90 = $18.

Subtract the savings from the original price to get the sale price: $90 - $18 = $72. You're all set!

Answer:

thus the father is 64 years and son is 37years

Step-by-step explanation:

Let father be X and son be y

X=27+Y...........(I)

X-10=2(Y-10)

putting the value of X from eqn(I)

27+Y-10=2Y-20

Y+17=2Y-20

17+20=2Y-Y

37=y

X=27+Y

X=64

We are given the following information:

each person uses 3/8 a box

there are 6 boxes

Because each box is , and there are 6 boxes, we know that 1 person is , or .

In order to find how many people can use the 6 boxes, we can divide it by 3 (for each use):

48 / 3 = 16

Therefore, 16 people can share the worms.

Answer:

[tex]A= 53[/tex]

Step-by-step explanation:

Given

[tex]BC = 9,6[/tex]

[tex]AC = 7.2[/tex]

Required: Angle A

This is calculated using:

[tex]tan\ A = \frac{Opposite}{Hypotenuse}[/tex]

From the attachment;

[tex]Opposite = 9.6[/tex]

[tex]Adjacent = 7.2[/tex]

So:

[tex]tan A =\frac{9.6}{7.2}[/tex]

[tex]tan A =1.333[/tex]

Take arctan of both sides

[tex]A= tan^{-1}(1.333[/tex]

[tex]A= 53[/tex]----- approximated
