Solve 2,401 = 76 – 2x.
Answers
Subtract 2,401 from both sides.
0 = 76 - 2401 - 2x
0 = -2325 - 2x
Add 2x on both sides.
2x = -2325
Divide both sides by 2.
x = -2325 / 2
x = -1162.5

Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals. Maggie keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns over another tile without looking. What is the probability that the second tile that Maggie turns over has a plant on it?
Answers
Answer:6/8 - - - - simplified 3/4
Step-by-step explanation: removing the tile she just flipped over would be 6 plants and 2 animals so there would be 8 total tiles and you would putt the remaining tiles over it like so 6/8 meaning out of the remaining 8 tiles 6 of them are plants giving her a 6 in 8 chance or a 3 in 4 chance
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
We are given that Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals .
Number of tiles with picture of plants =7
Number of tiles with picture of animals =2
Total number of tiles =7+2=9
We have to find the probability that the second tile that Maggie turns over has plant on it .
When she removes one tile of picture of plant then she has number of tiles of picture of plants =6
Total number of tiles =8
Probability,P(E)=[tex]\frac{Number\;of\;favorable\;cases}{Total\;number\;of\;cases}[/tex]
Using the formula then we get
The probability that she finds tile of picture of plant =[tex]\frac{6}{8}=\frac{3}{4}[/tex]

Step-by-step explanation:
In the table -1 and 1 are equal to 5, which is also shown in C.
Since k is a transformed function, a graph that shows the parent function of k is: C. graph C.
Generally speaking, a function can be stretched by multiplying it with the absolute value of a numerical value that is either greater than 1 or less than -1.
Additionally, you should multiply the x-variable with the shrink or stretch factor when compressing (shrinking) or stretching a function horizontally.
Since the numbers 1 and -1 both yield the same output value, it ultimately implies that the graph of the parent function must be a parabola and a quadratic function;
As x decreases from -1, k(x) would increase.
As x increases from 1, k(x) would increase.

Write and solve an equation to answer the question,
"5 is 5% of what number w?"
An equation is blank =0.05 blank .

Answers
The mathematical representation of '5 is 5% of what number?' is 5 = 0.05w. To solve for w, we divide 5 by 0.05, which gives us a value of w=100.
Explanation:To solve the question, '5 is 5% of what number w?', we can set up the equation as 5 = 0.05w. This equation represents the statement '5 is 5% of some number w' in mathematical terms. To find the value of w, we divide both sides of the equation by 0.05. The calculation goes like this:
Set up the equation: 5 = 0.05wDivide both sides by 0.05: w = 5 / 0.05Perform the division to find the value of w: w=100Learn more about Math Percentage here:

#SPJ12
The equation to find the number for which 5 is 5% is: 5 = 0.05w. The solution to the equation is w = 100.
To write and solve the equation that represents the given statement, we can let 'w' represent the unknown number.
The equation is:
5 = 0.05w
Solving for w, we divide both sides by 0.05:
w = 5 / 0.05
w = 100
Therefore, the solution to the equation is w = 100. This means that 5 is 5% of 100.

the perimeter of a parallelogram is 72 meters. the width of the parallelogram is 4 meters less than it's length. Find the length and the width of the parallelogram
Answers
Answer:
Length is 18 meters and width is 14 meters
Step-by-step explanation:
You can solve for the length by using the perimeter formula.
P = 2l + 2w.
You know P = 72. You also know the length is l and the width is w = l - 4.
72 = 2l + 2(l - 4)
72 = 2l + 2l - 8
72 = 4l - 8
72 = 4l
18 = l
This means the width which is 4 meters less is 18 - 4 = 14.

Drawing A Red Tile From A Bag And Then Drawing A Green Tile After Replacing The First Tile. Dependent Or Independent?
Answers
Answer:
Independent
Step-by-step explanation:
with replacement the total number of tiles will always remain the same,i.e the sample size will not be changed. so the events are independent.
Drawing a red tile from a bag and a green tile after replacing the first tile are independent events because the composition of the bag remains unchanged, meaning the probability of drawing the green tile remains constant.
When drawing a red tile from a bag and then drawing a green tile after replacing the first tile, the two events are considered independent. The outcome of drawing the green tile does not depend on the outcome of drawing the red tile. This is because when the first tile is replaced, the composition of the tiles in the bag remains unchanged, resulting in the probability of drawing a green tile being the same regardless of the previous draw. This is known as sampling with replacement.
If, however, the first tile was not replaced, the events would then be dependent, because the removal of the red tile would alter the composition of the bag, affecting the probability of drawing a green tile on the second draw. This is referred to as sampling without replacement. An example of dependent events is a scenario where if a bag contains four blue and three white marbles, and a marble is drawn and not replaced, the probability of drawing a marble of a particular color would change for the second draw.

Please help with this normal distribution problem
Answers
900 = 750 + 2*75. In other words, 900 is 2 standard deviations away from the mean. Similarly, 975 is 3 standard deviations from the mean. So
[tex]P(900<X<975)=P(2<Z<3)[/tex
where [tex]X[/tex] is the random variable for the lifespan of a light bulb with the given normal distribution, and [tex]Z=\dfrac{X-750}{75}[/tex] with the standard normal distribution.
We get
[tex]P(2<Z<3)\approx0.0214=2.14\%[/tex]
If you don't have a calculator/lookup table available, you can invoke the empirical rule, the one that says
[tex]\begin{cases}P(-1<Z<1)\approx68\%\\P(-2<Z<2)\approx95\%\\P(-3<Z<3)\approx99.7\%\end{cases}[/tex]
The normal distribution is symmetric about its mean, so we also know
[tex]\begin{cases}P(0<Z<1)\approx34\%\\P(0<Z<2)\approx47.5\%\\P(0<Z<3)\approx49.85\%\end{cases}[/tex]
Then
[tex]P(2<Z<3)=P(0<Z<3)-P(0<Z<2)\approx2.35\%[/tex]
Answer:
0.021
Step-by-step explanation:
One way in which to approach this problem solution is to use a calculator that has statistical distribution functions built in. My old TI-83Plus has the function "normalcdf," which does the job nicely.
Typing in normalcdf(900,975,750,75) results in the probability 0.021 that a light bulb chosen at random will last between 900 and 975 hours.
Using a table of z-scores would be a good alternative approach. Note that the z-score corresponding to 750 hours is 0; that for 900 is +2; and that for 975 is +3. Find the area under the standard normal curve to the left of 975 (z = 3) and that to the left of 900 (z = 2), and then subtract the two results. It will be 0.021, as before.
