Answer:
500.85 to 519.15
Step-by-step explanation:
The computation is shown below;
The z value for the 98% confidence interval is 2.33
Now the margin of error is
= (z × standard deviation) ÷ √n
= (2.33 × 36) ÷ √87
= (83.88 ) ÷ √87
= 83.88 ÷ 9.327379
= 8.99
= 9
Now The confidence interval mean is
= (510 - 9) (510 +9)
= (501) ; (519)

Step 1: Define
3b + 12 > 27 - 2b
Step 2: Solve for b
Add 2b on both sides: 5b + 12 > 27Subtract 12 on both sides: 5b > 15Divide 5 on both sides: b > 3Here we see that any value b greater than 3 would work as a solution to the inequality.

Imagine your playing a game, you are currently level 5 and it takes 55 EXP to level up to level 6, each battle you fight you gain 3 EXP, how many battles would it take to level up? you don't have to show your work :).
Step-by-step explanation:
55 / 3 = 18.333.
Since it is a decimal, we round up to the nearest whole number.
It will take at least 19 battles to level up.
Answer:
Step-by-step explanation:
so divide 55 / 3 = 18.33333333 or 18 1/3 but.. you'll have to battle 19 times to level up

Johnny takes an Uber to a toy store to buy some slime. Each container of slime costs $5 dollars. The Uber charges a total of $10 dollars. Write an expression that represents Johnny's total cost after buying s containers of slime, including the Uber ride. What is Johnny's total cost if he buys 17 containers of slime, including the Uber ride?
Answer:
Total cost will be $45 if he buys 17 containers of slime, including the Uber ride.
Step-by-step explanation:
Cost of one container of slime = $5
Cost of Uber = $10
We need to write an expression that represents Johnny's total cost after buying s containers of slime, including the Uber ride.
Total cost = Cost of slime containers + Cost of Uber
Total Cost = 5s+10
So, the required equation is: [tex]Total\: Cost = 5s+10[/tex]
Now, we need to find What is Johnny's total cost if he buys 17 containers of slime, including the Uber ride?
We have s= 17
So, the cost of buying 17 containers of slime and Uber ride will be:
[tex]Total\: Cost = 5s+10\\Put\:s=17\\Total\: Cost = 5(7)+10\\Total\: Cost = 35+10\\Total\: Cost = 45[/tex]
So, Total cost will be $45 if he buys 17 containers of slime, including the Uber ride.

A ball is thrown straight up in the air at a velocity
of 100 feet per second. The height of the ball at t seconds
is given by the formula: h = 100t – 5t^2 Find the
maximum height of the ball and when it will land. Maximum Height ____ ft. Land after: ___ seconds
Answer:
Maximum height = 500 feet
Land after = 20 seconds
Step-by-step explanation:
Let us follow the movement of the ball as it is thrown upwards. We notice that we get to a point, where the change in the height of the ball with respect to time becomes = 0. This means that the ball is at its maximum position.
Hence, mathematically, at maximum height, [tex]dh/dt = 0[/tex]
Recall,
[tex]h = 100t - 5t^2[/tex]
[tex]dh/dt=100-10t[/tex]
From our problem, we can also deduce that at the maximum height, the velocity of the ball is = 0. i.e [tex]dh/dt = 0[/tex]
hence,
[tex]0 = 100-10t\\t =10 seconds[/tex]
The time the ball takes to reach a maximum height is 10 seconds.
The next step will be to substitute this time value into the equation for the height.
[tex]h = 100(10) -5(10)^2=500 feet[/tex]
The maximum height is 500 feet
The object will land after t X 2 seconds = 10 X 2 = 20 seconds. This is because it will have to go up and come back down. This should take twice the time.

15. If f(x) = -x2 + 2x, find f(3) - 7.
Answer:
-10
Step-by-step explanation:
Find f(x) = - x^2 + 2x first
f(3) = -(3)^2 + 2(3)
f(3) = - 9 + 6
f(3) = - 3
Now do f(3) - 7
f(3) - 7 = - 3 - 7
f(3) - 7 = - 10

Answer:
3y+5 ≤ 17
Step-by-step explanation:
ok so we need she is buying a certain amount of markers but we don't know exactly how many so it would be 3y
we also know that she brought ONE notebook for 5 dollars which is why it would be 3y + 5
because the total amount will soon add up
now the reason it is ≤ 17
is because the symbol "≤" means less than or equal to
she did NOT spend MORE than 17 but we do not know if she spent exactly 17 or less.

For each equation, determine whether it is linear.
(a) y=x-6
(b) y= 4x
(C) y= 3x2-4
(d) y=-x)
Answer:
b
Step-by-step explanation:
solve for rational algebraic equation.
Step-by-step explanation:
Taking the provided equation ,
[tex]\implies \dfrac{3x+4}{5}-\dfrac{2}{x+3} =\dfrac{8}{5} [/tex]
1) Here denominator of two fractions are 5 and x +3 . So their LCM will be 5(x+3)
[tex]\implies \dfrac{(x+3)(3x+4)-(2)(5)}{5(x+3)}=\dfrac{8}{5} [/tex]
2) Transposing 5(x+3) to Right Hand Side . And 5 to Left Hand Side .
[tex]\implies 5(3x^2+4x+9x+12 -10) = 40(x+3)[/tex]
3) Multiplying the expressions.
[tex] \implies 5(3x^2+13x+2) = 40x + 120 [/tex]
4) Opening the brackets .
[tex]\implies 15x^2+ 65x + 10 = 40x + 120 [/tex]
5) Transposing all terms to Left Hand Side .
[tex]\implies 15x^2 + 65x - 40x + 10 - 120 = 0 \\\\\implies 15x^2 +25x - 110 = 0[/tex]
6) Solving the quadratic equation .
[tex]\implies 5(3x^2+5x -22) = 0 \\\\\implies 3x^2+13x-22 = 0 \\\\ \implies x = \dfrac{-b\pm \sqrt{b^2-4ac}}{4ac} \\\\\implies x = \dfrac{-5\pm \sqrt{5^2-4(-22)(3)}}{2(3)} \\\\\implies x = \dfrac{-5\pm \sqrt{289}}{6}\\\\\implies x =\dfrac{-5\pm 17}{6} \\\\\implies x = \dfrac{17-5}{6},\dfrac{-17-5}{6}\\\\\implies x = \dfrac{12}{6},\dfrac{-22}{6} \\\\\underline{\boxed{\red{\bf\implies x = 2 , \dfrac{-11}{3}}}}[/tex]
Answer:
[tex]x=2\\x=-\frac{11}{3}[/tex]
Step-by-step explanation:
Solve the rational equation:
[tex]\displaystyle \frac{3x+4}{5}-\frac{2}{x+3}=\frac{8}{5}[/tex]
To eliminate denominators, multiply by 5(x+3) (x cannot have a value of 3):
[tex]\displaystyle 5(x+3)\frac{3x+4}{5}-5(x+3)\frac{2}{x+3}=5(x+3)\frac{8}{5}[/tex]
Operate and simplify:
[tex]\displaystyle (x+3)(3x+4)-5(2)=(x+3)(8)[/tex]
[tex]\displaystyle 3x^2+4x+9x+12-10=8x+24[/tex]
Rearranging:
[tex]\displaystyle 3x^2+4x+9x+12-10-8x-24=0[/tex]
Simplifying:
[tex]\displaystyle 3x^2+5x-22=0[/tex]
Rewrite:
[tex]\displaystyle 3x^2-6x+11x-22=0[/tex]
Factoring:
[tex]\displaystyle 3x(x-2)+11(x-2)=0[/tex]
[tex]\displaystyle (x-2)(3x+11)=0[/tex]
Solving:
[tex]x=2\\x=-\frac{11}{3}[/tex]

A single die is rolled twice. Find the probability of rolling a 2 the first time and a 4 the second time
Explanation:
The probability of rolling a "2" is 1/6
The probability of rolling a "4" is also 1/6
Multiplying those fractions leads to (1/6)*(1/6) = 1/36. We can multiply the probabilities because the events are independent. Each dice roll does not affect any others.
The probability of rolling a 2 the first time and a 4 the second time is 1/36
There are 6 faces on a die.
Of these 6 faces, one of them is 2 and one of them is 4
So, the probabilities of rolling a 2 and a 4 are:
P(2) = 1/6
P(4) = 1/6
The probability of rolling a 2 the first time and a 4 the second time is calculated as follows:
[tex]\mathbf{Pr = P(2) \times P(4)}[/tex]
This gives
[tex]\mathbf{Pr = \frac 16 \times \frac 16}[/tex]
Multiply
[tex]\mathbf{Pr = \frac 1{36}}[/tex]
Hence, the probability of rolling a 2 the first time and a 4 the second time is 1/36
