hellpmeh i kinda get it

Answer:

A. 109

Step-by-step explanation:

We know that since AB = CB, then ΔABC is isosceles.

Since AC, one of the sides of ΔABC, is on the diameter of circle D, by definition, we know that ΔABC is also a right triangle. Thus, if ΔABC is an isosceles right triangle, then ∠BAC = ∠BCA = 45°.

Draw a line connecting D to B so that we now have isosceles triangle BDC. Since arc BC is 52°, by definition of central angles, ∠BDC is also equal to 52°. Then, ∠DBC = ∠DCB = (180 - 52)/2 = 64°.

∠BCE = ∠DCB + ∠BCA

∠BCE = 64 + 45 = 109°

The answer is thus A.

P(B given A) = P(A and B) / P(A)

P(B given A) = 0.10 / 0.20

P(B given A) = 0.50

Answer:

D

Step-by-step explanation:

not positive but i think it would be D

Option C is the distributions are positively skewed.

Since, A distribution that is positively skewed would have the following highlights:

More points on the left, if represented on a dot plot

Tall bars on the left, if represented on a histogram

Whisker on the left, if represented on a box plot

The above means that none of the distributions are positively skewed.

This is so because:

A is negatively skewed because the whisker is at the right

B and C are symmetrical because there are tall bars at the middle

D is positively skewed because the whisker is at the left.

Hence, Option D is the distributions are positively skewed.

Answer:

parallel = 4/3

perpendicular =-3/4

Step-by-step explanation:

Solve for y

-4x+3y=11

Add 4x to each side

3y = 4x+11

Divide by 3

y = 4/3 x +11/3

This is in the form y = mx+b where m is the slope

m =4/3

The parallel line has the same slope

parallel slope is 4/3

The perpendicular line has a negative reciprocal slope

m = -(1 /4/3) = - 3/4

Answer:

[tex]\frac{4}{3}[/tex] and - [tex]\frac{3}{4}[/tex]

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 )

Given

- 4x + 3y = 11 ( add 4x to both sides )

3y = 4x + 11 ( divide all terms by 3 )

y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{11}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{4}{3}[/tex]

Parallel lines have equal slopes, thus

slope of parallel line = [tex]\frac{4}{3}[/tex]

Give a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{3} }[/tex] = - [tex]\frac{3}{4}[/tex]

Answer:

(0,9.8) and (10,1.2)

Step-by-step explanation:

it makes the best line

The two ordered pairs can be joined to draw most accurately the line of best fit for this scatter plot are (0, 9.8) and (10, 1.2).

Option B is the correct answer.

A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.

In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.

The position of each point on the graph represents the values of both variables for that particular observation.

We have,

To determine which two ordered pairs can be joined to draw the most accurate line of best fit for the scatter plot, we need to look for pairs of points that are representative of the overall trend in the data.

We can plot the given points and visually inspect the scatter plot to find the line of best fit.

From the scatter plot, we can see that there is a general downward trend from left to right and that the points are somewhat scattered around this trend.

One possible way to draw the line of best fit is to connect the points (0, 9.8) and (10, 1.2).

This line represents the overall trend in the data and passes close to many of the given points.

Therefore,

The two ordered pairs can be joined to draw most accurately the line of best fit for this scatter plot are (0, 9.8) and (10, 1.2).

Answer:

radius is the other quantity needed, which appears listed as option C in the list of possible answers.

Step-by-step explanation:

Recall that the volume of a cone is given by the formula:

[tex]Vol=\frac{1}{3} B\,*\, H[/tex]

where B is the area of the base:

[tex]B=\pi\,R^2[/tex]

with R being the cone's radius at the base, and H the cone's height.

The formula for the surface area of the cone also needs the size of the radius.

Therefore, the radius is the other needed quantity.

Answer:

C) Radius.

Step-by-step explanation:

When looking at a shape like this is is crucial to know the circumference because Area is L*W*H In order to determine your width you will need the Radius.

Answer:

w = 5

Step-by-step explanation:

Expand brackets.

-4w - 4 = -24

Add 4 on both sides.

-4w = -20

Divide both sides by -4.

w = 5

Answer:

w=5

Step-by-step explanation:

First, you do -4 times w and -4 times 1, which equals -4w+-4.

Then, you take -4 to the other side and it becomes -24+4=-20.

Now, you have -4w= -20

Lastly, you you divide -20/-4= 5.

w=5

Answer:

2nd quadrant.

Step-by-step explanation:

The given function is

[tex]h(x)=-6+\dfrac{2}{3}x[/tex]

We need to find the quadrant from which the graph of function is not passing.

At x=0,

[tex]h(0)=-6+\dfrac{2}{3}(0)=-6[/tex]

So, y-intercept is (0,-6).

At h(x)=0,

[tex]0=-6+\dfrac{2}{3}x[/tex]

[tex]6=\dfrac{2}{3}x[/tex]

[tex]18=2x[/tex]

[tex]9=x[/tex]

So, x-intercept is (9,0).

It means the graph intersect negative side of y-axis and positive side of x-axis. When we join these two points, we get the graph is not passing through the 2nd quadrant.

Therefore, the required quadrant is 2nd quadrant.

Answer:

36 units.

Step-by-step explanation:

we will use concept of basic proportionality theorem,

it states that , when a line is drawn parallel to one side of the triangle and intersect the other two sides then the two sides are divided in the same ratio.

Example:

In a triangle ABC

If  DE is  parallel to BC

D is a point on line AB and E is  point on AC, then

by basic proportionality theorem)

AD/DB = AE/EC

_____________________________________

in the problem  given one side has a parallel line drawn to it

Hence we can use basic proportionality theorem in it

20/30 = 24/?

2/3 = 24/?

=> ? = 24*3/2 = 36

Hence, missing segment value is 36 units.

Answer:

[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]

Step-by-step explanation:

Given

[tex]h(x) = 3(x+2)^2[/tex]

[tex]h(x) = (fog)(x)[/tex]

Required

Find possible expressions for f(x) and g(x)

[tex]h(x) = (fog)(x)[/tex]

This can be rewritten as:

[tex]h(x) = f(g(x))[/tex]

Recall that [tex]h(x) = 3(x+2)^2[/tex]

So;

[tex]h(x) = f(g(x)) = 3(x+2)^2[/tex]

[tex]f(g(x)) = 3(x+2)^2[/tex]

By comparison, the expression in bracket represents g(x);

Hence;

[tex]g(x) = x + 2[/tex]

Replace g(x) with x

[tex]f(x) = 3(x)^2[/tex]

[tex]f(x) = 3x^2[/tex]

Hence, the possible expressions of f(x) and g(x) are:

[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]

Step-by-step explanation:

The given figure has four equal sides, and all adjacent sides are perpendicular to each other.

Quadrilateral is a any figure with four sides.

Particular quadrilaterals have specific names.

A square is a quadrilateral with equal sides, each perpendicular to the adjacent side, as shown in the figure.

A rectangle is a quadrilateral of which all sides are perpendicular to the adjacents.  Therefore opposite sides are equal.  Adjacent sides MAY or MAY NOT be equal.   Therefore a square is also a rectangle.

A rhombus is a quadrilateral of which all four sides are equal, but adjacent sides MAY or MAY NOT be perpendicular.  Therefore a square is also a rhombus.

A trapezoid (or trapezium, depending on which side of the atlantic you live) is a quadrilateral with AT LEAST one pair of parallel sides.  The other pair may or may not be equal, may or may not be parallel.  Therefore a square is also a trapezoid (trapezium).

A quadrilateral is any plane figure with four sides, which may or may not be parallel, may or may not be equal, and adjacent sides may or may not be perpendicular.  Therefore a square is also a quadrilateral.

So the given figure could be given all six possible names indicated in bold.  However, the name square is most specific.

Answer:

147

Step-by-step explanation:

We want to find the value of a² + √b, so let's plug in 12 for a and 9 for b:

a² + √b

12² + √9

The square root of 9 is 3 because 3 * 3 = 9, while the square of 12 is 144 because 12 * 12 = 144.

144 + 3 = 147

The answer is thus 147.

Step-by-step explanation:

Let x be that number.

4 + 3 × x = 19

4 + 3x = 19

Add -4 on both sides.

4 + 3x - 4 = 19 - 4

3x = 15

Divide both sides by 3.

(3x)/3 = 15/3

x = 5

Answer:

4+3x=19 so, x=5

19-4= 15, 15/3=5 or 5*3=15, 19-15=4.
