Which value of a would make the inequality statement true? 9.53 < startroot a endroot < 9.54 85 88 91 94
The value of a lies between 90.8209 and 91.0116 is 91. Then the correct option is C.
What is inequality?Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.
The inequality is given as
9.53 < √a < 9.54
On squaring both sides, we have
9.54² > a > 9.53²
91.0116 > a > 90.8209
Thus, the value of a lies between 90.8209 and 91.0116 is 91. Then the correct option is C.

A baker uses 84 cups of flour for 36 batches of cookies. How many cups of flour are needed for 1 batch of the cookies?.
Answer:
23/10
Step-by-step explanation:
To find the unit rate divide 84 by 36
84 ÷ 36 = 2.3
To convert 2.3 to a faction
2.3 = 2.0 + 0.3
0.3 = 3/10
3/10 + 2 = 2 3/10
2 3/10 = 23/10

Step-by-step explanation:
Select all of the pieces of information that would tell you x and y have a proportional relationship. Let y represent the distance between a rock and a turtle's current position in meters and x represent the number of minutes the turtle has been moving. y=3x After 4 minutes, the turtle has walked 12 feet away from the rock. The turtle walks for a bit, then stops for a minute before walking again. The turtle walks away from the rock at a constant rate.
Answer:
y=3x
The turtle walks away from the rock at a constant rate.
Step-by-step explanation:
A proportional relationship is one in which the two variables vary directly with each other and can be represented by the equation:
y = kx, where k is the constant of proportionality.
Also, a proportional relationship has a constant rate which is the ratio of the two variables.
A) The equation y = 3x is a proportional relationship because it is in the form y = kx, k =3
B) After 4 minutes, the turtle has walked 12 feet away from the rock.
We cant say that this is a proportional relationship because it may or may not be proportional.
C) The turtle walks for a bit, then stops for a minute before walking again.
It is not proportional
D) The turtle walks away from the rock at a constant rate
This is a proportional relationship because it has a constant rate
please helllppp i don’t understanddd
Answer:
B
Step-by-step explanation:
First off, let's make a table for y = sin(x)
(x , y): (0 , 0) (π/2 , 1) (π , 0) (3π/2 , -1) (2π , 0)
Now, making our table for y = 4sin(x) is simple. We just have to multiply all the y-values from the previous table by 4.
(x , y): (0 , 0) (π/2 , 4) (π , 0) (3π/2 , -4) (2π , 0)
Plotting these coordinates, we get the graph depicted in letter B.

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting at least 1 blue?
Answer:
There is a 38% chance at least 1 was blue
Step-by-step explanation:
there are 8 marbles total 3 being blue. 3/8= .375 = 38%
The probability of getting at least 1 blue marble in the given situation is 0.375, i.e., 37.5%.
Probability is the ratio of favorable outcomes to the total number of outcomes.
It is given that there are 3 blue and 5 red marbles in the bag.
Therefore, the total number of marbles in the bag is 8.
Let's take two scenarios, one when one blue marble and one red marble are drawn and the second one when both marbles drawn are blue.
Let B and R be the events of drawing a blue marble and red marble, respectively.
Case 1:
The probability of getting one blue and one red marble is calculated as follows:
[tex]P(B =1, R=1) = \dfrac{3}{8}\times\dfrac{5}{7}[/tex]
[tex]= \dfrac{15}{56}[/tex]
Note that the replacement is prohibited.
Case 2:
The probability of getting two blue marbles is calculated as follows:
[tex]P(B =2) = \dfrac{3}{8}\times\dfrac{2}{7}[/tex]
[tex]= \dfrac{6}{56}[/tex]
The probability of getting at least 1 blue marble is given as follows:
[tex]P(B\ge1) = P(B =1, R=1) + P(B =2)[/tex]
[tex]= \dfrac{15}{56}+ \dfrac{6}{56}\\= \dfrac{21}{56}\\=\dfrac{3}{8}\\= 0.375[/tex]
Therefore, the probability of getting at least a blue marble is 0.375.

Tracy says the quadratics below
factors to (x + 6)(x – 6). Is she
correct? Explain in words or show
work to prove your answer.
x2 – 12x + 36
Answer:
no!
One way is to work backwards and check the factored form (x+6)(x-6) using the FOIL method.
Multiply the first terms, then outside terms, then inside terms, then last terms. Simplify and you will find the extended version of (x+6)(x-6) to be x^2-36, NOT the expression x^2-12x+36.
4p + 5 + p = 2p + 5 + 3p
P= -2
All real numbers
P = 2
P= 5
Answer:
P = All real numbers
Step-by-step explanation:
Step 1: Write equation
4p + 5 + p = 2p + 5 + 3p
Step 2: Solve for p
Combine like terms: 5p + 5 = 5p + 5Subtract 5 on both sides: 5p = 5pDivide both sides by 5: p = pHere we see that any value p would render the equation true. Therefore, we have an infinite amount of solutions.

Step-by-step explanation:
The number of pieces in a regular bag of Skittles is approximately normally distributed with a mean of 38.4 and a standard deviation of 2.12.
a)What is the z-score value of a randomly selected bag of Skittles that has 35 Skittles? a) 1.62 b) -1.62 c) 3.40 d) -3.40 e)1.303.
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
z = 35 - 38.4/2.12

Explain whether the points (−3,8), (−2,3), (−1,−2), (0,−7), (1,−12), and (2,−17) represent the set of all the solutions for the equation y=−5x−7.
A.Yes, because all solutions in the set of solutions for y=−5x−7 need to have integer values for both x and y.
B.Yes, because all of the points that are listed are on the line y=−5x−7.
C.No, because the x-intercept is not provided in the list of points.
D.No, because the set of all solutions of y=−5x−7 is represented by the line of the equation
Answer:
D
Step-by-step explanation:
We simply put each of the points to test
For a point to be correct, if we substitute the x-coordinate value, we should get the value of the y-coordinate
So let’s proceed
(-3,8)
8 = -5(-3) - 7
8 = 15 -7
8 = 8
(-2,3)
3 = -5(-2) - 7
3 = 10 -7
3 = 3
(-1,-2)
-2 = -5(-1) - 7
-2 = 5-7
-2 = -2
(0,-7)
y = -5x -7
y = -5(0) - 7
y = 0-7 = -7
(1,-12)
y = -5(1) -7
-12 = -5 -7
-12 = -12
(2,-17)
-17 = -5(2) -7
-17 = -10-7
-17 = -17
We can see that all the listed points are on the given line
Although all these points lie on the line, we cannot say they represent the set of all solutions
The set of all solutions can simply be represented by the line of the equation
