Answer:

5√2

Step-by-step explanation:

With reference angle 45°

perpendicular (p) = 5

hypotenuse (h) = x

sin 45 ° = p / h

1/√2 = 5 / x

x = 5√2

Answer:  To establish the strength of a linear association, first compute the correlation coefficient between the variables involved. The, examine the absolute value of the coefficient. A strong relationship has an absolute value of close to 1 (or approaching 1) while a weak relationship has an absolute value close to 0 (or approaching zero).

The data points will be clustered more tightly around the trend line if there is a weak linear association and less tightly if there is a strong one.

Answer:

a) 0.5 = 50% probability that an NPN transistor will be selected.

b) 0.3333 = 33.33% probability that it came from the cabinet that contains both types

c) 66.67% probability that it comes from the cabinet that contains only NPN transistors

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

a) What is the probability that an NPN transistor will be selected?

1/3 probability that the first cabinet is chosen. This cabinet has two transistors, both of which are NPN, so 100% probability of selecting a NPN transistor.

1/3 probability that the second cabinet is chosen. This cabinet has two transistors, both of which are PNP, so 0% probability of selecting a NPN transistor.

1/3 probability that the second cabinet is chosen. This cabinet has two transistors, one of which is NPN, so 50% probability of selecting a NPN transistor.

So

[tex]p = \frac{1}{3}*1 + \frac{1}{3}*0 + \frac{1}{3}*0.5 = \frac{1}{3} + \frac{1}{6} = \frac{2}{6} + \frac{1}{6} = \frac{3}{6} = 0.5[/tex]

0.5 = 50% probability that an NPN transistor will be selected.

b) Given that the hobbyist selects an NPN transistor, what is the probability that it came from the cabinet that contains both types?

Here we use the conditional probability formula.

Event A: NPN transistor

Event B: From the third cabinet.

50% probability that an NPN transistor will be selected, so [tex]P(A) = 0.5[/tex].

1/6 probability that it is from the third cabinet and NPN, so [tex]P(A \cap B) = \frac{1}{6}[/tex]

The desired probability is:

[tex]P(B|A) = \frac{\frac{1}{6}}{0.5} = 0.3333[/tex]

0.3333 = 33.33% probability that it came from the cabinet that contains both types.

c) Given that an NPN transistor is selected what is the probability that it comes from the cabinet that contains only NPN transistors?

Either it comes from the cabinet with only NPN transistors, or it comes from the cabinet with both types of transistors. The sum of the probabilities of these outcomes is 100%. So

x + 33.33 = 100

x = 66.67

66.67% probability that it comes from the cabinet that contains only NPN transistors

Answer: 32 degrees

Step-by-step explanation:

small angle : x

middle angle: x + 20

large angle: 3x

Form an equation: 5x + 20 = 180

5x = 180 - 20

5x = 160

x = 160/5

x = 32

the answer is letter B

[tex]\frac{1}{5}[/tex] — 6[tex]\frac{2}{5}[/tex] = [tex]\frac{31}{5}[/tex] or [tex]\frac{4}{5}[/tex]

The amount of money paid for the 9-day rental will be $1000.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Mr White is renting a small truck for one week and a few additional days d. He does not have to pay a per-mile fee. The expression is 280+80d.

The amount of money for a 9-day rental will be calculated as,

A = 280+80d

A = 280+(80 x 9)

A = $1000

Therefore, the amount of money paid for the 9-day rental will be $1000.

Answer:

the value of 3b ÷ a is 3 ÷ 70

Step-by-step explanation:

The computation is shown below:

Given that

a × b = 70

So it could be write as

a = 70 ÷ b

And, the value of 3b ÷ a is

= 3b ÷ 70 ÷ b ÷ 1

= 3b ÷ 70b

= 3 ÷ 70

Hence, the value of 3b ÷ a is 3 ÷ 70

The value of the variable 'x' will be 25. Then the correct option is B.

If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral. And the sum of opposite angles of the quadrilateral is 180 degrees.

Quadrilateral EFGH is inscribed in a circle as shown. ∠F = (4x + 10)°, ∠G = (2x - 5)º, and ∠H = (3x - 5)°.

Angles ∠F and ∠H will be supplementary angles. Then the equation is given as,

∠F + ∠H = 180

4x + 10 + 3x - 5 = 180

7x = 175

x = 25

The value of the variable 'x' will be 25. Then the correct option is B.

Answer:

[tex]Opposite =- \frac{4}{5}[/tex]

Step-by-step explanation:

Given

[tex]Number = \frac{4}{5}[/tex]

Required

Determine its opposite

To get the opposite of a number, we simply subtract it from 0.

So, we have:

[tex]Opposite =0 - \frac{4}{5}[/tex]

[tex]Opposite =- \frac{4}{5}[/tex]

Hence, the opposite is -4/5

Hey in this type of questions there's no formula, you need to use your logic.

#Note that the full degree or a triangle is 180°

#The L in triangle is 90°

I see that you want to try to do it by yourself, i will give you the tips. to get the <BAD

#since <DAC is 90°, The ADB is 90° (180°-90°)

<BAD = 180° - 90° - 25° = 65°

Now, try to find <BCA yourself.

Tell me if you give up, i will tell you lol.
