Answer:

4 lbs left after 5 days

Step-by-step explanation:

First, you need to step up an equation!

You know that Soomin has a total of 20 pounds and that she's using it, so you are going to use subtraction.

She uses 3 1/5 pounds per day so you write:

20 - 3 1/5x

and you know that she wants to know how much she has left after 5 days so you replace the x with 5:

20 - (3 1/5) * 5

Multiply first:

20 - 16

After Subtracting you get the answer:

4 lbs left

x^2+1/2x+1/16=4/9 Factor the perfect-square trinomial on the left side of the equation. (x + )² = 4/9
Nezavi [6.7K]
The missing number is the square-root of the constant term on the left-hand-side, which equals sqrt(1/16)=1/sqrt(16)=1/4.
Check:
(x+1/4)^2=x^2+2*(1/4)x+(1/4)^2=x^2+x/2+1/16.   ok

Answer: x= 1/4

Among 400 randomly selected drivers in the 16 minus 18 age​ bracket, 293 were in a car crash in the last year. If a driver in th
professor190 [17]

Answer:

The approximate probability is 0.7325.

Is not unlikely that a driver in that age bracket is involved in a car crash during a​ year, so there are reasons to be concerned.

Step-by-step explanation:

The approximate probability can be estimated using the sample proportion:

p=\dfrac{X}{n}=\dfrac{293}{400}=0.7325

A probability of 0.7325 is high, so it is not unlikely that a driver in that age bracket is involved in a car crash during a​ year.

As this value is high, there is reasons to be concerned about it.

KATRIN_1 [288]

Answer:

250 cookies

Step-by-step explanation:

The employee burns 55 chocolate chip cookies

if this represented 22% of the days production

Let x = the total production of cookies for the day

how many cookies did you plan on producing that day?

22% of x = 55

22 / 100 * x = 55

0.22x = 55

Divide both sides by 0.22

x = 55 / 0.22

= 250

x = 250 cookies

Therefore, the total production of cookies for the day is 250

The correct answer is

c) Neither person is correct because light does not change frequency when it travels through different media

we have given that The column on the right is labeled speed of light in meters per second and are all times 10 Superscript 8 Baseline with entries 2. 25, 2. 99, 1. 97, 1. 24.

<h3>What happened when light travels through the different media?</h3>

light changes both wavelength and speed when it travels through different media, but the frequency remains the same

light changes both wavelength and speed when it travels through different media, but the frequency remains the same.

Therefore the option c is correct that

Neither person is correct because light does not change frequency when it travels through different media
