Lin won't be charged $5.95 per day because her account balance is quite above zero(0), except her account balance falls down to zero, then she would be charged for subsequent deposits made into the account daily.

Answer:

Step-by-step explanation:

Subtract 7 from both sides.

We have:

-3z-4z=21

So:

-7z=21

21/-7 = -3

The answer is C.

Answer:

Base = 3√5

Step-by-step explanation:

Given:

Hypotenuse = 9

Perpendicular = 6

Find:

Base(x)

Computation:

Using Pythagorean theorem

Base = √Hypotenuse² - Perpendicular²

Base = √9² - 6²

Base = √81 - 36

Base = √45

Base = 3√5

Answer:

Answer:

The sum of two side lengths of a triangle must be greater than the length of the third.

So, if two side lengths are 3 and 7, the length of the third side must be less than 10 units.

However, it cannot be shorter than 4 units, as 3 + 4 = 7.

So your answer is: The third side of this triangle must not be shorter than 4 or longer than 10

Answer:

[tex] {2b}^{2} + 32b + 128[/tex]

Factor and get

[tex]x = - 8[/tex]

Answer:

Fraction form: -1/2

Decimal form: -0.5

Step-by-step explanation:

1: Subtract 7 from both sides

7 - 6x = 9 - 2x

7 - 7 - 6x = 9 - 7 - 2x

6x = 2 - 2x

2: Add 2x on both sides

6x + 2x = 2 - 2x + 2x

-4x = 2

3: Divide both sides by -4 to get x by itself

-4x/-4 = 2/-4

x = -1/2

(Which can also be written as -0.5 in decimal form )

Answer:

Yes by SAS

Step-by-step explanation:

if you do 42 / 18 you see that the relationship between the sides is 2.3333... so that is one proportional side

Then, you see that there is one angle in both triangles that is 76 degrees, so that is one equal angle

then, you can do 21 / 9 = 2.33333... which is the same as the first proportion which means that is another proportional side.

then you have a side, angle, and a side, so it's SAS

Answer:

238 miles

Step-by-step explanation:

340 miles = 5 hours

So get 1 hour by dividing by 5 on both sides

5/5 = 1 hr

340/5 = 68

So in 1 hour they travel 68 miles

You want to find 3 1/2 hours

Do 68 x 3 to get 3 hours

So it would be 68 x 3 =204

Plus the half an hour - which you get by doing 68/2 = 34

68 = 1 hour, so half of that must be half an hour

So to get the final distance you do 204 (3 hours) +34 (half an hour)

204 + 34 =238

Answer + Explanation:

let x be the measure of angle x

let y be the measure of angle y

[tex]\left \{ {{x + y = 180} \atop {x=24+y}} \right.[/tex]

Now, solve:

plug x = 24 + y into x + y = 180

24 + y + y = 180

24 + 2y = 180

2y = 156

y = 78

Now, plug this back into the equation x = 24 + 78

x = 102

Answer:

x= 102

y= 78

Step-by-step explanation:

x+y=180

x= y + 24

2x-24 = 180

Answer: 99%?

Step-by-step explanation:

She was at 40 feet below, she swam up getting so she was then at 40-10 = 30 feet below sea level.

She the swan 4 feet down so she ended up at 30 + 4 = 34 feet below sea level.

The answer is 34 feet below sea level (-34)

Answer:

Domain: 7,2

Range: 9,7

Slope is 2/5

Step-by-step explanation:

Domain is basically the x coordinates, which are 7 and 2 in this case. Range is the y coordinates: 9 and 7.

The slope is basically the line that connects these two dots.

Slope formula is (y2-y1)/(x2-x1)

But the points of the grid would be listed as (x1,y1) (x2,y2)

I don't know if I'm explaining this well enough, but if you follow that formula you get (7-9)/(2-7).

That equals to 2/5.

I hope this helped

Answer:

139

Step-by-step explanation:

Cause it is

The smallest sample size that will produce the desired interval is 139.

Option C is the correct answer.

The margin of error is the amount of error or uncertainty in a statistical estimate, usually an estimate of a population parameter based on a sample.

We have,

The formula for calculating the margin of error for a confidence interval is:

Margin of error =  z x (√(p x (1-p))/√(n))

where:

z =  the z-score corresponding to the desired confidence level

p =  the estimated proportion of the population that exhibits the behavior of interest (in this case, using a certain brand of a mobile phone)

n =  sample size

We want the margin of error to be at most 0.07, which means we need to solve for the smallest possible value of n that satisfies this condition.

We also want a 90% confidence interval, which corresponds to a z-score of 1.645.

Therefore,

we have:

0.07 = 1.645 x (√(p*(1-p))/√(n))

Squaring both sides and solving for n, we get:

n = ((1.645)² x p x (1-p)) / (0.07)²

We don't know the value of p, so we need to use the worst-case scenario, which is when p = 0.5 (which gives the largest possible value of n for any given margin of error).

Plugging this into the formula, we get:

n = ((1.645)² x  0.5 x (1-0.5)) / (0.07)²

n = 138.55

Since n must be a whole number, the smallest sample size that will produce the desired interval is 139.

Therefore,

The smallest sample size that will produce the desired interval is 139.
