Answer:

the z-score for the sat score of 380 is 2

Step-by-step explanation:

the way i got this is you got to take the standard deviation value and subtract it from the mean since the value 380 is less than 500.

500-60=440-60=380

so the answer would be a z-score of 2

Answer:

[tex]x^{5/6 } + 2\cdot x^{7/3}[/tex]

Step-by-step explanation:

Let be [tex]x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2})[/tex], which can be simplified solely by algebraic means. We proceed to describe all the steps needed for simplification:

1) [tex]x^{1/3}\cdot (x^{1/2} + 2\cdot x^{2})[/tex]  Given.

2) [tex]x^{1/3}\cdot x^{1/2} + 2\cdot (x^{1/3}\cdot x^{2})[/tex] Distributive and associative properties.

3) [tex]x^{5/6 } + 2\cdot x^{7/3}[/tex] [tex]a^{m}\cdot a^{n} = a^{m+n}[/tex]/Result

Answer:

55 tickets for adults

Step-by-step explanation:

Start by setting up two equations. One equation will be the total amount of money spent and the other is the total amount of tickets sold. a is the # of adult tickets and c is the # of children tickets sold.

7a+4c=469

a+c=76

Now solve for c in the second equation. Then use that to substitute for c in the first equation.

c=76-a

7a+4(76-a)=469

7a+ 304-4a =469

7a+4a=165

3a=165

a=165/3

a=55

Answer:

9. 3 ÷ 4, 9.5, 9. 3 ÷ 8, 9.125

Step-by-step explanation:

Given that

The weight of four puppies are 9.5 9 3 ÷ 8 9.125 9 3 ÷ 4

We need to find out the weight from high to low

So,

First we place the number in decimals

After this, we line all up

Now place the numbers from high to low

The above shows the correct order

Therefore the same would be considered and relevant

Slope = change in y over change in x

Slope = (-20 -20)/ (11-25)

Slope = -40/ -14

Slope = 20/7

Answer: I belive b, I could be wrong  tho.

Step-by-step explanation:

Answer:

I think that the answer is B

3x²+x-5=0

a = 3, b = 1, c= -5

-> ∆ ( delta ) = b²-4ac = 61 > 0

-> x1 =( -b+√∆ )÷ 2a =...

x2 = (-b-√∆)÷2a =...

p/s: do your teachers teach you how to use ∆ ( delta ) in maths calculation ? i live in europe and our teachers teach us that way. however, it is a rịght and fast way. you should learn it.

Answer:

Mixed Number: 7 And 1/10

Improper Fraction: 71/10

Please give me Brainliest if I'm right ! :)

Answer:

Mixed Number: 7 1/10

Improper Fraction: 71/10

Step-by-step explanation:

A Mixed Number is a Number with a fraction as part of it so 7 is a whole number, so this is the "number" part. .1 isnt a whole number, so you find out what the simplified form of .1 is, and you get 1/10. Put them together and you get 7 1/10. An improper fraction is where the number becomes only a fraction, no whole numbers allowed! you can find out 1 = 10/10 so this means 7 = 70/10. Add the .1 (1/10) to this and you get 71/10.

Answer:

2x+h

Step-by-step explanation:

f(x+h) means that wherever there's an x in the function f(x) we plug in a x+h

we have

(x+h)²+9

Let's start with the numerator

(x+h)²+9-(x²+9)

Distribute the exponent

x²+2xh+h²+9-x²-9

Which gives us

2xh+h²

Divide the whole thing by h to give us

2x+h

Answer:

45/2

Step-by-step explanation:

ashjasdhkjasdha hello there

There are two people and there are 45 minutes to shoot the ball. As both people shoot for the exact same time, you have to divide 45 by 2 to split the time into two equal halves. Thus, the answer is 45 divided by 2, or just 45/2.

Answer:

offer an entertaining and enjoyable shopping experience.

Step-by-step explanation:

Hedonistic is a word in English language used to describe the pursuit of pleasure by an individual or group of people as the main activity of life. A hedonistic individual is typically devoted to seeking and having fun and pleasurable times in life.

Hence, a store that provides hedonic benefits will offer an entertaining and enjoyable shopping experience such as playing video games, swimming, viewing centers, playing music or karaoke, etc. The main purpose of hedonic benefits is to induce or enhance customer impulsiveness, as well as influencing their decision to stay longer in the shopping environment or store.

Answer:

[tex](x+1)^2+(y-2)^2=49[/tex]

Step-by-step explanation:

The standard form for the equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where  r  is the radius, and the center is (h, k).

(h, k) = (-1, 2),  r = 7

[tex](x-(-1))^2+(y-2)^2=7^2\\\\(x+1)^2+(y-2)^2=49[/tex]

Answer: 384 fluid ounces

Step-by-step explanation:

First and foremost, when converting gallons to ounces, the conversion rate is:

1 gallon = 128 ounces

Therefore, since Trevor's mom bought 3 gallons of fruit juice, to convert it to to ounces, we have to multiply by 128. This will then be:

1 gallon = 128 ounces

3 gallons = 128 ounces × 3

= 384 fluid ounces of fruit juice.

Answer:

$500 will give the company the maximum revenue

Step-by-step explanation:

Given

[tex]r(x) = x (1000 - 2x)[/tex]

Required

Price to generate maximum revenue

We have:

[tex]r(x) = x (1000 - 2x)[/tex]

Open bracket

[tex]r(x) = 1000x - 2x^2[/tex]

Rewrite as:

[tex]r(x) = - 2x^2 + 1000x[/tex]

The maximum value of x is calculated using:

[tex]x = -\frac{b}{2a}[/tex]

Where:

[tex]f(x) = ax^2 + bx + c[/tex]

So:

[tex]a \to -2[/tex]

[tex]b = 1000[/tex]

[tex]c = 0[/tex]

[tex]x = -\frac{b}{2a}[/tex]

[tex]x = -\frac{1000}{-2}[/tex]

[tex]x = \frac{1000}{2}[/tex]

[tex]x = 500[/tex]

Answer:

The third one counting from the top.

Step-by-step explanation:

We have the inequality:

(-1/3)*(2x + 1) < 3

The first thing we need to do is isolate x on one side of the inequality.

First we can by -3 in both sides of the inequality, and remember, because we are multiplying by a negative number, the inequality sign changes its direction:

(-3)*(-1/3)*(2x + 1) > 3*(-3)

(2x + 1) > -9

Now we can subtract 1 in both sides:

2*x + 1 - 1 > -9 - 1

2*x > -10

Now we can divide by 2 in both sides:

2*x/2 > -10/2

x > -5

Then we should see a number line such that all the points at the right of -5 are colored.

The correct option is the third one, counting from the top.
