Answer:

a = 3

Step-by-step explanation:

AB/AC = 7/8 = 14a/48

7/8 = 14a/48

Multiply both sides by 8.

7 = 14a/6

Multiply both sides by 6 and switch sides.

14a = 42

a = 3

Answer: =1.34

Step-by-step explanation:

In standard density curve

P(Z<z) = Area left of z, P(Z>z) = area right of z.

P(Z<z) +P(Z>z) =1

Given:  z is a standard normal random variable.

To find : value of z if rea to the right of z is 0.01.

i.e. P(Z>z) =0.01

P(Z<z) =1-0.01 = 0.09

from z-score table, z value for this is 1.34.

Hence, z= 1.34

Add the colors together to get total pieces:

2 + 2 + 3 + 5 = 12 total pieces.

Blue and green = 2 + 2 = 4 pieces.

Picking blue of green would be 4/12 which reduces to 1/3

The answer is A. 1/3

Answer:

1) y = -1

2) y = 3

3) y = 5

4) y = 9

Step-by-step explanation:

1) when x = -2

y = 2x + 3

y = 2(-2) +3

y = -1

2) when x = 0

y = 2x + 3

y = 2(0) +3

y = 3

3) when x = 1

y = 2x + 3

y = 2(1) +3

y = 5

4) when x = 3

y = 2x + 3

y = 2(3) +3

y = 9

=(8)2+(0)2‾‾‾‾‾‾‾‾‾‾√

=64+0‾‾‾‾‾‾√

=6‾√4

=8

Answer:

See below.

Step-by-step explanation:

The unit rate is the cost per thing. You just divide the cost by the amount:

$7.38/18 ounces = $0.41/1 ounce

$15.39/27 ounces = $0.57/1 ounce

Therefore, $7.38 for 18 ounces is the better option.

Answer:

3500 ÷ 50 = 70

The linear functions are 1/3x=y-3 and y=2/3x. Therefore, options A and D are the correct answer.

A linear function is a function that represents a straight line on the coordinate plane. The highest power of the variable is one.

Given are some equation, from the options, we need to identify which is a linear function.

1/3x=y-3 is the linear function in two variables.

y=x³ is the cubic function.

y=6x² is the quadratic function.

y=2/3x is the linear function in one variable.

Therefore, the linear functions are 1/3x=y-3 and y=2/3x.

Answer:

  C.  41.0, θ = 77.3°

Step-by-step explanation:

The sum is ...

  5(8, 4) -3(-3, -4) +8(-5, 1) = (5·8-3(-3)+8(-5), 5·4-3(-4)+8·1)

  = (40+9-40, 20+12+8) = (9, 40)

The magnitude is ...

  √(9² +40²) = √1681 = 41

The angle is ...

  arctan(40/9) ≈ 77.3°

The resultant magnitude and direction is 41∠77.3°.

Answer:

41.0, θ = 77.3°

Answer:

300,000

Step-by-step explanation:

3 ten thousands = 30,000

30,000 * 10 = 300,000

Hope this helps :)

10 times as much as 3 ten thousand is equal to 300,000.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the number is 10 times as much as 3 ten thousand. The number will be calculated as below:-

3 ten thousands = 30,000

30,000 x  10 = 300,000

Therefore, 10 times as much as 3 ten thousand is equal to 300,000.

Answer and Step-by-step explanation:

(a) Since the student have to stop when he gets to w softcover book, then the sample space should always stop at either 3 or 4 or 5. If the students examines the books randomly and stops at a softcover book, here are the possible ways he could carry this out,

S = {3, 4, 5, 13, 14, 15, 23, 24, 25, 123, 124, 125, 213, 214, 215}

2. Since only one book is to be examined then the student must check only one softcover book and end the examining. To do this, either he examines just 3 or 4 or 5. Therefore,

A = {3, 4, 5}

3. We need to pick the possibilities from the sample space that shows that the examining ended at book 5. Therefore,

B = {5, 15, 25, 125, 215}

4. We need to pick possibilities from the sample space that shows that book 1 was not examined. Therefore,

C = {3, 4, 5, 23, 24, 25}
