Answer:

The probability is 0.16602

Step-by-step explanation:

We start by calculating the z-score

We have this mathematically as;

z-score = (x-mean)/SD/√n

From the question,

we have x = 6.15

mean = 6.06 hours

standard deviation = 0.55 hours

n = 35

Substituting these values, we have

z-score = (6.15-6.06)/0.55/√35

z-score = 0.09/0.55/5.92

z-score = 0.97

So the probability we want to calculate is:

P ( z > 0.97)

we make use of the standard normal distribution table here

The value is; 0.16602

Answer:

D the amount of money he pays for each lunch

Step-by-step explanation:

In each lunch Devante has, he pays 2,50 $ according to:

Money in t = t₀     he has  35,50 $      paid 3 lunches and spent

35,50 - 28  =  7,5

Then the cost of each lunch is    7,5 / 3   =  2,5 $

After that

bought    5 lunches and spent   28  - 15,5  = 12,50

Again    12,5 / 5   =  2,5 $

Now the model for the situation is a straight line with a slope 2,5

In an  x , y cartesian system in which  y is money in the account  and x is the number of lunches, such a straight line will be

y  =  b  -  m*x      ( b the intercept on y  and  m the negative slope)

y  =  35,50 - 2,5*x

So  answering the question is lyrics  D  the amount of money he pays for each lunch

Answer:

y =x +5

Step-by-step explanation:

Slope-intercept form : y = mx + b

y - 1 = x + 4

    y = x + 4 + 1

  y = x + 5

Answer:

C. 4k-3

Step-by-step explanation:

Step 1: Remove parentheses.

7-3k-4+5k-6+2k

7−3k−4+5k−6+2k

Step 2: Combine like terms.

(7-4-6)+(-3k+5k+2k)

(7−4−6)+(−3k+5k+2k)

Step 3: Simplify.

-3+4k

Step 4: Regroup terms.

4k-3

I hope this helps!

A brainliest will be appreciated.

Answer:

C. 4k - 3.

Step-by-step explanation:

(7 - 3k) - (4 - 5k) - (6 - 2k)

Distributing the negative over the last 2 parentheses:

= 7 - 3k - 4 + 5k - 6 + 2k

=  -3k + 5k + 2k + 7 - 4 - 6

= 4k -3.

Answer:

Positive

Step-by-step explanation:

Both of the numbers are positive and the first number is bigger than the second, so it has to be positive.

I hope this helps, and have a great day! :)

Answer:

In many instances, the lyrics to folk songs came from existing nursery rhymes or poems, and some of the nursery rhymes had variations, depending on region or time. Thus, these folk songs may have lyrics that are slightly different from those you are familiar with.

Therefore, in my opinion, I think that Nursery songs can be considered folk music.

Answer:

C = 0.475

Step-by-step explanation:

you divide 5.70 by 12 and get that one bagel costs 0.475 cents. hope this helps!

c=40 is the answer

6x55=330 cents

$570-570 cents (570-330)÷(12-)

=240÷6 (division)

=40 cents

Thus, c=40

The unitary method is a method for solving a problem by first finding the value of a single unit and then multiplying the value of a single unit to find the required value.

The unitary method is a procedure that calculates the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Simply put, the unitary method is used to find the value of a single unit from a given plural. For example, if the price of 40 pens is 400 rupees, the price of one pen would be: This can be done using a uniform method

Answer:

221.0 m

Step-by-step explanation:

First, find x using trigonometric ratio formula:

Reference angle = angle of depression = angle of elevation = 64°

Opposite side length = 142 m

Adjacent side length = x

Thus:

tan(64) = 142/x

x*tan(64) = 142

x = 142/tan(64)

x = 69.3 (nearest tenth)

Next, find distance from top of the hill to the buoy using Pythagorean Theorem.

Let the distance be y.

We would have:

y² = 142² + (69.3 + 100)²

y² = 20,164 + 28,662.49

y² = 48,826.49

y = √48,826.49

y = 221.0 m (nearest tenth)

Given :

Heather spend 2/7 of her money buying presents.

She then had €48.65 left.

To Find :

The initial amount of money she had.

Solution :

Let, initial amount she had is €x.

So,

[tex]x - \dfrac{2x}{7} = 48.65\\\\\dfrac{5x}{7} = 48.65 \\\\x = \dfrac{48.65\times 7}{5}[/tex]

x = €68.11

Therefore, initially he had €68.11 .

Answer:

$39

Step-by-step explanation:

First, let's get the values of each number by rounding them off to the nearest dollar before adding them.

1. $2.69 = $3

2. $14.45 = $14

3. $8.05 = $8

4. $13.95 = $14

Now that you have the rounded off numbers, you may add them.

Let's solve.

The estimated total is $39.

Answer:

7.12

Step-by-step explanation:

Standard form is writing a number with numbers instead of letters. Word form example: three. Standard form example: 3. Because the word "hundredths" has the "ths" at the end of it, on the right side of the decimal.

Total probability equals 1.

Subtract the probability of blue from 1:

1-0.4 = 0.6

Red and yellow total is 0.6

Since they have the same number of cubes, the probability of both would be the same so divide the remainder by 2:

0.6 /2 = 0.3

The probability of red is 0.3

The probability of yellow is 0.3

30 blue cubes with a probability of 0.4.

Let total cubes = x

30 blue/ x = 0.4

Multiply both sides by x:

30 = 0.4x

Divide both sides by 0.4

X = 30/0.4

X = 75

Total cubes is 75

This doesn’t make sense though because red and yellow are supposed to be the same and if you subtract blue from total it’s an odd number so red and yellow aren’t the same:

75-30 = 45

45/2 = 22.5
