My response: In arithmetic, a hundredth is a single part of something that has been divided equally into a hundred parts. For example, a hundredth of 675 is 6.75. In this manner it is used with the prefix "centi" such as in centimeter. A hundredth is the reciprocal of 100.

write the equation of the line that passes through (2,-4) and (-1,-1)

Answers

You need to use the y = mx + b formula which will get you to the answer
y = -x -2

Answer:

y = - x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (- 1, - 1)

m = [tex]\frac{-1+4}{-1-2}[/tex] = [tex]\frac{3}{-3}[/tex] = - 1 , thus

y = - x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 1, - 1 ), then

- 1 = 1 + c ⇒ c = - 1 - 1 = - 2

y = - x - 2 ← equation of line

Answers

Answer:

Option d (quantitative data) is the correct choice.

Step-by-step explanation:

Quantitative data seems to be a collection or kind of data which is concerned regarding quantitative information or methods. That indicates its value, as well as the condition, could be represented arithmetically. All evidence that can be quantified, checked, and suitable for statistical analysis categorizes as quantitative methods.

The remaining three options do not apply to the specified scenario. Therefore the description made will serve as an example of quantitative data.

5x + 11 = 4x + 18 and describe the steps!!!

Answers

Answer:

x = 7

Step-by-step explanation:

First, put the x values on one side by subtracting 4x from each side:

5x + 11 = 4x + 18

x + 11 = 18

Subtract 11 from both sides to solve for x:

x = 7

Answer: The value of x is 7.

Step-by-step explanation:

Here's how I got my answer:

5x + 11 = 4x + 18

Isolate variables and combine like terms:

5x - 4x = 18 - 11

Simplify:

x = 7

Step-by-step explanation:

A circle is defined by x^2+y^2+2gx+2fy-15=0. The gradient of the tangent to the circle at the point (3,2) is -1/2. Find the value of g and f​

Answers

Answer:

  (g, f) = (-1, 2)

Step-by-step explanation:

The equation can be put into standard form:

  (x^2 +2gx) +(y^2 +2fy) = 15

  (x^2 +2gx +g^2) +(y^2 +2fy +f^2) = 15 +g^2 +f^2

  (x +g)^2 +(y +f)^2 = 15 +g^2 +f^2 . . . . equation in standard form

The point (3, 2) is on the circle, so one of the equations we have is ...

  (3+g)^2 +(2 +f)^2 = 15 +g^2 +f^2

  9 +6g +g^2 +4 +4f +f^2 = 15 +g^2 +f^2

  6g +4f = 2 . . . . . . . subtract g^2 +f^2 +13

  3g +2f = 1 . . . . . . . divide by 2

__

A line through the center of the circle is perpendicular to the tangent at the point of tangency. That line will have a slope that is the negative reciprocal of the tangent's slope: m = -1/(-1/2) = 2. Then in point-slope form the equation of the line through the center is ...

  y -2 = 2(x -3)

  2x -y = 4 . . . . rearrange to standard form

The point at the center of the circle, (-g, -f), satisfies this equation, so we have another relation for f and g:

  2(-g) -(-f) = 4

  2g -f = -4 . . . . . . multiply by -1

Adding twice this equation to the one above, we have ...

  2(2g -f) +(3g +2f) = 2(-4) +(1)

  7g = -7 . . . . . . . . . simplify

  g = -1 . . . . . . . . . . divide by 7

  f = 2g +4 = 2(-1) +4 = 2 . . . find the corresponding value of f

The values of f and g are: f = 2 and g = -1.

Write an equation to solve for x, then solve for x. The whole question is in the picture.

Explanation:

Let's solve your equation step-by-step.

6(−2w−3)=−4(3w+7)+10

Step 1: Simplify both sides of the equation.

6(−2w−3)=−4(3w+7)+10

(6)(−2w)+(6)(−3)=(−4)(3w)+(−4)(7)+10(Distribute)

−12w+−18=−12w+−28+10

−12w−18=(−12w)+(−28+10)(Combine Like Terms)

−12w−18=−12w+−18

−12w−18=−12w−18

Step 2: Add 12w to both sides.

−12w−18+12w=−12w−18+12w

−18=−18

Step 3: Add 18 to both sides.

−18+18=−18+18

g In a one-tail hypothesis test where you reject H0 only in the lower tail, what is the p-value if Z STAT

Answers

Answer:

The P-value is 0.0166.

Step-by-step explanation:

The complete question is: In a​ one-tail hypothesis test where you reject H0 only in the lower ​tail, what is the p-value  if ZSTAT = -2.13.

We are given that the z-statistics value is -2.13 and we have to find the p-value.

Now, the p-value of the test statistics is given by the following condition;

                    P-value = P(Z < -2.13) = 1 - P(Z [tex]\leq[/tex] 2.13)

                                  = 1 - 0.9834 = 0.0166

Assuming that the level of significance is 0.10 or 10%.

The decision rule for rejecting the null hypothesis based on p-value is given by;

If the P-value of the test statistics is less than the level of significance, then we have sufficient evidence to reject the null hypothesis.If the P-value of the test statistics is more than the level of significance, then we have insufficient evidence to reject the null hypothesis.

Here, the P-value is more than the level of significance as 0.0166 > 0.10, so we have insufficient evidence to reject the null hypothesis, so we fail to reject the null hypothesis.

The hypotenuse of one side of a right angled triangle are 5cm and 4cm respectively. what is the length of the other side

Answers

Answer: 3cm

Explanation:

We can use Pythagorean’s theorem to find that other side:

a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3

Therefore, the other side is 3cm

Answer:

Hypotenuse is the longest side in a triangle.

a^2=b^2+c^2.

5^2=4^2+c^2.

c^2=25-16.

c^2=9.

c=√9.

c=3cm.

Suppose that the height s of a ball (in feet) at time t (in seconds) is given by the formula s(t) = 64 - 16(t - 1)^2. This function is graphed below on the interval 0 ≤ t ≤ 3. Which labeled point (A-G) corresponds to the release of the ball? How high (in feet) was the ball when it was released? Which labeled point corresponds to the highest point of the ball? When (in seconds after being released) did the ball reach its highest point? Which labeled point corresponds to the ball hitting the ground? How long (in seconds) after being released did the ball hit the ground?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Suppose that the height s of a ball (in feet) at time t (in seconds) is given by the formula

s(t) = 64 - 16(t - 1)^2

t interval = 0 ≤ t ≤ 3

1) point A (from the graph)

11) Height of ball when it was released

Ball was released at t = 0

s(0) = 64 - 16(0 - 1)^2

= 64 - 16(-1)^2

= 64 - 16(1)

= 64 - 16

= 48 feets

111) point C ( from the graph)

IV) highest point of the ball is 64

Hence,

s(t) = 64 - 16(t - 1)^2

64= 64 - 16(t - 1)^2

16(t - 1)^2 = 64 - 64

16(t - 1)^2 = 0

16t^2 - 32t + 16 = 0

t^2 - 2t + 1 = 0

(t-1) = 0 (t-1) = 0

t = 1

V) Point G (from graph)

V1)

height = 0

s(t) = 64 - 16(t - 1)^2

0 = 64 - 16(t - 1)^2

16(t - 1)^2 = 64

(t - 1)^2 = 64/16

(t - 1)^2 = 4

(t - 1)² = 2²

t - 1 = 2

t = 2 + 1

t = 3
