Answer:

A. 1:4 is the answer of this question

Answer:

a

Step-by-step explanation:

there's a pattern that goes along with the 32 students in the 6th grade. since 8 is a factor (or multiple?) of 32, and 8x4 is 32, we can simplify.

so, 8 is the first multiple of 32 and 32 is the fourth. if we simplify that, we get 1:4.

the answer is 1:4.

Step-by-step explanation:

to find the equation of a line having the slope use this formula:

[tex]y - yp = m(x - xp)[/tex]

in which:

- yp is the y of the point (so 4);

- m is the slope (so 5);

- xp is the x of the point (so -1)

so:

[tex]y - 4 = 5(x - ( - 1))[/tex]

[tex]y - 4 = 5x + 5[/tex]

[tex]y=5x + 5 + 4[/tex]

P= (5.5, 8)

Q=(8.5,5)

Step-by-step explanation:

Coordinates of L: (2,7)

Coordinates of M: (9,9)

Coordinates of N: (8,1)

Midpoint formula is: [tex]\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]

P is the midpoint of LM, so the coordinates of P will be ((2+9)/2,(7+9)/2)

P's coordinates are (5.5, 8)

Q is the midpoint of MN, so the coordinates of Q will be ((9+8)/2,(9+1)/2)

Q's coordinates are (8.5,5)

Step-by-step explanation:

The two equations must equal 180 degrees. So what you could do it 4x + (2x + 12) = 180

then solve. If this isnt enough information just comment :)

If no I hope this helped

For the two lanes to be parallel, the value of x must be 28 degrees,

The given information states that the same-side interior angles are 4x degrees and (2x + 12) degrees.

For parallel lines, the sum of these angles must equal to 180 degrees.

As per the concept of linear sum,

4x + (2x +12) = 180

Adding the like terms, we get:

(4x + 2x) + 12 = 180

Simplifying, we get:

6x + 12 = 180

Subtract 12 to both sides, and we get:

6x = 180 - 12

Simplifying, we get:

6x = 168

x = 28

Therefore, the value of x is 28 degrees.

Given: Monthly salary of salesperson is $2400

         Incentive of salesperson is $250 per vehicle sold.

First, lets compute income to earned apart from salary.

∴ Deduct salary from the target amount

$2000 need to be earned only through incentive, which is $250 per vehicle sold.

Now, solving to get number vehicles to be sold to earn $2000 as incentive.

Number of vehicle=

Answer:

1/36

Step-by-step explanation:

So what you have to do is take all the numbers on the dice. Getting a 4 would be a 1 in 6 (1/6) chance, but then you take the risk of rolling again and trying to get another 4. Nothing changes with the amount of sides, so it would just be another 1/6 change to get the 4. Then, you have to multiply the two changes together. SO 1/6 x 1/6 = 1/36. It is a 1/36 chance to role a 4 on both roles.

The probability of an event is a number between  [tex]0[/tex] and [tex]1[/tex]. Hence, the probability of showing a [tex]4[/tex] on both the rolls is [tex]\frac{1}{36}[/tex].

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between  [tex]0[/tex] and [tex]1[/tex].

The probability of the first throw  [tex]4[/tex] is [tex]\frac{1}{6}[/tex].

And on the second throw is [tex]\frac{1}{6}[/tex].

For both, the throws probability [tex]4[/tex] would be

[tex]\frac{1}{6}[/tex]×[tex]\frac{1}{6}[/tex][tex]=\frac{1}{36}[/tex]

Hence, the probability of showing a [tex]4[/tex] on both the rolls is [tex]\frac{1}{36}[/tex].

The rational root theorem is used to determine the possible roots of a function.

The true statement is: (d) Any rational root of f(x) is a factor of 3 divided by a factor of 8.

The function is given as:

[tex]\mathbf{f(x) = 8x^3 - 4x^2 + 6x + 3}[/tex]

The possible roots of a function

[tex]\mathbf{f(x) = qx^n + ax^{n-1} +.....+ p}[/tex]

are

[tex]\mathbf{Roots = \pm\frac{Factors\ of\ p}{Factors\ of\ q}}[/tex]

By comparison: p = 3 and q = 8

So, we have:

[tex]\mathbf{Roots = \pm\frac{Factors\ of\ 3}{Factors\ of\ 8}}[/tex]

Hence, the true option is (d) Any rational root of f(x) is a factor of 3 divided by a factor of 8.

Answer:

B. Roxanne made a mistake at step 5. She should have used x - 1/2 as the new upper bound.

Step-by-step explanation:

Based on the successive approximation method, Roxanne made a mistake at step 5. She should have used x = -1/2 as the new upper bound.

In Science, successive approximation can be defined as a classical method that is used in Calculus for solving integral equations or initial value problems.

In this scenario, Roxanne started the first iteration of successive approximation by using the lower and upper bounds of the graph. However, we can deduce that Roxanne made a mistake at step 5 because she should have used x = -1/2 as the new upper bound.
