At the beginning of Grade 6, the ratio of advanced math students to the number of regular math students was 3: 8. After taking placement tests, students we removed around changing the ratio of advanced students to the number of regular students to 4: 7. How many students started in regular math and advanced math if there were 92 students in advanced math after the placement test?

Answer:

Step-by-step explanation:

The confidence interval is an interval that determines an unknown population parameter. It showcases the probability that a particular population parameter will fall within this interval. As the sample size reduces, the width of the confidence interval usually increases.

What the given question mean is that one can still be 95% confident that the mean drive-through service times of this​ fast-food chain is between 175.2 seconds and 178.2 seconds.

Answer:

Yes.

Step-by-step explanation:

In order to check if an equation is true, plug in the corresponding values for x and y.

Coordinates are written as (x, y). So, x = 3 and y = 6.

Plug in these values to the equation.

6 = 2 * 3

Multiply 2 and 3 to simplify:

6 = 6

This shows that the equation is true when given (3, 6)

Answer:

x = 66

Step-by-step explanation:

The similarity ratio is DO/PA = 27/18 ➡3/2

So DT/PN ➡ x/44 = 3/2

132 = 2x divide both sides by 2

x = 66

Answer:

The coordinates of B are (1,6)

Step-by-step explanation:

Point Reflection

Given the point P(x,y) and its reflection P'(x',y') with respect to the point C(xc,yc), C is the midpoint of the segment PP'.

This means the coordinates of C are:

[tex]\displaystyle x_c=\frac{x+x'}{2}[/tex]

[tex]\displaystyle y_c=\frac{y+y'}{2}[/tex]

If the coordinates of the midpoint are given, then the endpoint P' can be found solving for x' and y':

[tex]x'=2x_c-x[/tex]

[tex]y'=2y_c-y[/tex]

The point P' is the reflection of P over C.

We are given the coordinates of A(-5,4) and the point (-2,5). We need to find the coordinates of point B(x',y'). Let's use the formulas as if A was point P and C=(-2,5):

[tex]x'=2(-2)-(-5)=-4+5=1[/tex]

[tex]y'=2(5)-4=10-4=6[/tex]

The coordinates of B are (1,6)

Answer:

40 tickets

Step-by-step explanation:

Given that:

Total tickets sold = 200

Sue's chances of winning = 20% = 0.2

Number of tickets bought by Sue :

P(winning) = 20%

P(winning) = required outcome / Total possible outcomes

Required outcome = number of tickets bought by Sue

Total possible outcomes = total number of tickets sold

0.2 = x / 200

x = 0.2 * 200

x = 40

Answer:

t = 2.525 seconds

Step-by-step explanation:

h(t) = -16t^2 + v*t + h0  h(t) = the height above the ground after t seconds v = 40 ft/s initial velocity  h0 = 4 ft the initial height of the object (the ball)  t = the time of the motion  h(t) = -16t^2 + 40*t + 4  we need to find t such that h(t) = 3 ft  3 = -16t^2 + 40*t + 4  -16t^2 + 40*t + 4 = 3  by solving we find

t = 2.525 seconds

You can round on your own.

Solving the quadratic equation, it is found that the ball was in the air for 1.97 seconds.

The height of the ball, in feet, after t seconds is given by:

[tex]h(t) = -16t^2 + v(0)t + h(0)[/tex]

In this problem:

Thus, the equation is:

[tex]h(t) = -16t^2 + 30t + 5[/tex]

The juggler catches the ball when it falls back to a height of 2 feet, thus it stays in the air until t for which:

[tex]h(t) = 2[/tex]

Then:

[tex]2 = -16t^2 + 30t + 5[/tex]

[tex]-16t^2 + 30t + 3 = 0[/tex]

[tex]16t^2 - 30t - 3 = 0[/tex]

Which is a quadratic equation with coefficients [tex]a = 16, b = -30,c = -3[/tex]. Then:

[tex]\Delta = b^2 - 4ac = (-30)^2 - 4(16)(-3) = 1092[/tex]

[tex]x_{1} = \frac{30 + \sqrt{1092}}{2(16)} = 1.97[/tex]

[tex]x_{2} = \frac{30 - \sqrt{1092}}{2(16)} = -0.1[/tex]  

The ball stays in the air for 1.97 seconds.

Answer:

12 servings

Step-by-step explanation:

Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6 pounds of ground turkey?

From above question:

2.5 pounds of ground turkey = 5 servings

6 pounds of ground turkey = x

Cross Multiply

2.5 × x = 6 × 5

x = 6 × 5/2.5

x = 12 servings

Hence, 6 pounds of ground turkey can make 12 servings.

Completing the explanation.

The equation is

5x = 2.5y

where:

x = represent how many pounds of ground turkey he has = 6 pounds

y = to represent how many servings he can make

Hence,

5 × 6 = 2.5y

y = 5 × 6/2.5

y = 12 servings

Answer:

The vertex of the quadratic function is:

[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=x^2+6x+16[/tex]

As the vertex of the form [tex]y=ax^2+bx+c[/tex] is defined as:

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

As the quadratic function of parabola params are

[tex]a=1,\:b=6,\:c=16[/tex]

so

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

[tex]x_v=-\frac{6}{2\cdot \:1}[/tex]

[tex]x_v=-3[/tex]

Putting [tex]x_v=-3[/tex] to determine [tex]y_v[/tex]

[tex]y_v=\left(-3\right)^2+6\left(-3\right)+16[/tex]

[tex]y_v=3^2-18+16[/tex]

[tex]y_v=9-2[/tex]

[tex]y_v=7[/tex]

Therefore, the vertex of the quadratic function is:

[tex](x_{v}, y_{v})=\left(-3,\:7\right)[/tex]

Answer: The slope is undefined

Step-by-step explanation:

Answer:

undefined

Step-by-step explanation:

slope equation is y2-y1/x2-x1

use points (-2,2) and (-2,-2)

insert values into equation: -2-2/-2+2

simplify: -4/0

if the zero is on top of the fraction, then the slope is zero but since the zero is on the bottom, the slope has to be undefined

Answer: C. 00:00 $927; Vince wrote the wrong number to represent the interest rate.

Step-by-step explanation:

Given that:

Amount borrowed (p) = 900

Simple interest (r) = 1.5% = 0.015

Time (t) = 2 years

Amount he'll pay back (A) :

A = P(1 + rt)

A = 900(1 + 0.015(2))

A = 900(1 + 0.03)

A = 900(1.03)

A = $927
