Answer 1

Answer:

b. Hо : μ ≥ 40.1; Ha : μ > 40.1

Step-by-step explanation:

Note: The complete options to the question is attached as picture below

The alternative hypothesis is focusing on "the recession has led to a reduction in the average work week".

So, it will be less than the past average. i.e, 40.1.. so, we will use a less than (<) sign to write the alternative hypothesis.

The hypotheses are as below:

Hо : μ ≥ 40.1 (Null hypothesis)

Ha : μ > 40.1 (Alternative hypothesis)

Computer Scientist lol I need 20 characters

The correct answer is computer scientists because they know both discrete math and java.

Given that,
"There exists either a computer scientist or a mathematician who knows both discrete math and Java." is to be discussed.

What is java?

Java is a computer programming language, which helps to build software and program on computers.

here,
Mathematicians do have knowledge of discrete math but they do not have known what actually java is, while being a computer scientist one should have knowledge of both discrete math and Java.

Thus, the correct answer is computer scientists because they know both discrete math and java.

Answer:

30 degrees

Step-by-step explanation:

we need to compute angle A and angle B (see figure below)

hence,

[tex]cosA=\frac{20}{40}\\ cosA=\frac{1}{2}[/tex]

this implies that A=60 degrees.

Since interior angles of a triangle add up 180 then,

A+B+90=180

60+B+90=180

B+150=180

B=180-150

B=30 degrees

which is the smallest angle

Answer:

Step-by-step explanation:

firstly you calculate all in brackets

(280+20)÷3

300÷3

100-15

85

now you calculate 10×5=50

2×50=100

85+100=185

so firstly deal with problem inside the brackets, then you got multiplication and division outside their brackets and finally get 85 +100 =185

What is the area of the figure?

A. 36 cm2
B. 26 cm
C. 15 cm
D. 42 cm2

Answers

Answer:

Sorry to break it to ya but the other answer is wrong and the correct answer is A. 36 cm^2

Step-by-step explanation:

1. Divide the figure into 2 figures.

2. Calculate the first figure by multiplying the length (7 cm) and width (4 cm).

3. After that, we get 28. Do the same to the other figure. (4 cm x 2 cm = 8 cm).

4. Combine the 2 areas to get your total area. (28 + 8 = 36 cm^2).

5. NEVER forget the "^2" meaning squared when calculating the area.

What is a rectangle?

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

Example:

The area of the rectangle with a length of 3 cm and wide 5cm is 15 cm².

We have,

A figure.

The figure has two rectangles.

One rectangle:

Length = 4 cm

Wide = 7 cm

Area of the rectangle = 4 x 7 = 28 cm²

Another rectangle:

Length = 2 cm

Wide = 4cm

Area of the rectangle = 2 x 4 = 8 cm²

The area of the figure.

= 28 + 8

= 36 cm²

Thus,

The area of the figure is 36 cm².

Answers

Answer:

y = Ce⁻ᵗ − 7

Step-by-step explanation:

dy/dt = -y − 7

dy/dt = -1 (y + 7)

Separate the variables.

dy / (y + 7) = -1 dt

Integrate both sides.

ln│y + 7│= -t + C

Solve for y.

y + 7 = e⁻ᵗ⁺ᶜ

y + 7 = eᶜ e⁻ᵗ

eᶜ is another arbitrary constant, so:

y + 7 = Ce⁻ᵗ

In a certain country license plates consist of zero or one digit followed by four or five uppercase letters from the Roman alphabet.
(a) How many different license plates can the country produce?
(b) How many license plates have no repeated letter? (c) How many license plates have at least one repeated letter?
(d) What is the probability that a license plate has a repeated letter? (Round your answer to the nearest whole percent.)

Answers

Answer:

Step-by-step explanation:

From the given information:

The number of different license plate the country  can produce is in the form:

=L₁L₂L₃L₄   or  L₁L₂L₃L₄L₅  or  D₁L₁L₂L₃L₄   or    D₁L₁L₂L₃L₄L₅

The Total number of the license plate that can be produced is;

= 26⁴ + 26⁵ + (10 × 26⁴) + (10 × 26⁵)

= 456976 + 11881376 + 4569760 + 118813760

= 135721872

Number of license plate with no repeated letter = P(26,4) + P(26,5) + 10 P(26,4) + 10 P(26,5)

= 11 P(26,4P + 11 P(26,5)

[tex]=11 \times \dfrac{26!}{(26-4)!} + 11 \times \dfrac{26!}{(26-5)!}[/tex]

= 90776400

c) The number of the licensed plate with 1 repeated letter = Total number of the licensed plate - number of the licensed plate with no repeated letter.

= 135721872 - 90776400

= 44945472

d) The probability that a licensed plate has repeated letter is:

[tex]= \dfrac{no(rep \ letter) }{n (total)} \times 100\%[/tex]

[tex]= \dfrac{44945472}{135721872}\times 100\%[/tex]

= 33.12%

A) The country can produce 118,813,760 different licence plates.

B) 78,936,000 license plates have no repeated letter.

C) 39,877,760 license plates have at least one repeated letter.

D) The probability that a license plate has a repeated letter is 33.56%.

Given that in a certain country license plates consist of zero or one digit followed by four or five uppercase letters from the Roman alphabet, to determine (A) how many different license plates can the country produce; (B) how many license plates have no repeated letter; (C) how many license plates have at least one repeated letter; and (D) what is the probability that a license plate has a repeated letter, the following calculations must be performed:

A)

10 x 26 x 26 x 26 x 26 x 26 = X 10 x 11,881,376 = X 118,813,760 = X

B)

10 x 26 x 25 x 24 x 23 x 22 = X 10 x 7,893,600 = X 78,936,000 = X

C)

118,813,760 - 78,936,000 = X 39,877,760 = X

D)

118,813,760 = 100 39,877,760 = X 39,877,760 x 100 / 118,813,760 = X 33.56 = X
