Answer:

y=√(4+x)(4−x)

Step-by-step explanation:

Answer: x=−1 or x=1 or x=−2 or x=3

Step-by-step explanation: Step 1: Factor left side of equation.

(x+1)(x−1)(x+2)(x−3)=0

Step 2: Set factors equal to 0.

x+1=0 or x−1=0 or x+2=0 or x−3=0

x=−1 or x=1 or x=−2 or x=3

Answer: Nonlinear; power of x is greater than 1 (Bottom right corner)

Explanation:

The equation y = x^2 - 1 is known as a quadratic since the largest exponent here is 2. This equation cannot be written in slope intercept form y = mx+b, so that's why it's not linear. You can also graph y = x^2-1 to get a curved parabola. The graph must be a straight line if you want a linear equation.

Answer: 0.9972

Step-by-step explanation:

Let x be a random variable that represents the strength of concrete cylinders.

Given: The compressive strengths of 40 concrete cylinders have an estimated mean[tex](\mu)[/tex] of 60.14 MPa and standard deviation[tex](\sigma)[/tex] of 5.02 MPa.

The probability that 10 cylinders will each have strengths between 45 and 75 MPa :

[tex]P(45<\overline{x}<75)=P(\dfrac{45-60.14}{5.02}<\dfrac{\overline{x}-\mu}{\sigma}<\dfrac{75-60.14}{5.02})\\\=P(-3.016<z<2.96)\\\\=P(z<2.96)-P(z<-3.016)\\\\=P(z<2.96)-(1-P(z<3.016))\\\\=0.9985-(1-0.9987)\ \ \ [\text{by p-value table}]\\\\= 0.9972[/tex]

Hence, The required probability = 0.9972

Answer: 15

Step-by-step explanation:

45$ = 3 Tickets

45 / 3 = 1 Ticket

1 Ticket = 15

The cost of the concert ticket is 15 dollars per ticket.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We have been given that Three concert tickets cost $45.

To determine the cost per ticket.

Therefore,

45$ = 3 Tickets

For the unit cost of the concert ticket.

45 / 3 = 1 Ticket

1 Ticket = 15

Hence, the cost of the concert ticket is 15 dollars per ticket.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Z is the centroid of triangle.

The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle.

WR=87 SY=39 and YT=48

We need to find WS,WY,WZ,ZR,ZT and YZ

WS=39

As WS=WR

WY=WS+SY

WY=39+39=78

WZ=58

ZR=WR-WZ

ZR=87-48=29

ZT=16

YZ=YT-ZT

=48-16=32

YZ=32

Hence, the measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

Answer:

In the new mixture, the percentage of water with respect to its total is 13.33%.

Step-by-step explanation:

Given that in a liter of mixture 20% of it was water and the remaining 80% was pure milk, and that half a liter of wine was added to that liter of mixture, to determine the percentage of water in the new mixture is necessary to perform the following calculation:

20 + 80 + 50 = 150

150 = 100

20 = X

((20 x 100) / 150) = X

2,000 / 150 = X

13.33 = X

Thus, in the new mixture, the percentage of water with respect to its total is 13.33%.

Step-by-step explanation:

No, Kevin’s statement doesn’t make sense. He is correct that since the two equations have the same slope. Thus, they are parallel to each other.

However, since they are parallel, they will never touch. Therefore, there is no solution.

They will be infinitely many solutions if they are parallel and they have the same y-intercept.
