James is selecting a marble. James chooses a marble at random and then replaces it. He then selects a second marble at random. W
tresset_1 [31]

Answer:

The probability of selecting a solid black marbles both times;

P = 9/100

Attached is the completed question;

Step-by-step explanation:

Number of solid black marbles = 3

Total number of marbles = 10

The probability of selecting a solid black marble;

P1 = 3/10

With the assumption that the marbles are replaced before next selection.

The probability of selecting a solid black marbles both times;

P = P1 × P1 = 3/10 × 3/10 = 9/100

P = 9/100

A chord of a circular clock is 48 inches long, and its midpoint is 7 inches from the center of the circle. What is the radius of
Sphinxa [80]

ANSWER

The radius is 25 inches

EXPLANATION

From the diagram, the radius of the circle is AC.

From the Pythagoras Theorem,

{r}^{2}  =  {7}^{2}  +  {24}^{2}

r^{2}  =  49 +  576

Simplify

r^{2}  = 625

Take positive square root,

r =  \sqrt{625}

r = 25

Hence the radius is 25 inches

What does a residual value of 4. 5 mean in reference to the line of best fit? The data point is 4. 5 units above the line of bes
Kamila [148]

A line of best fit is a line drawn at average distance to a series of scattered points. Thus, the correct option is:

Option B. The <em>data</em> point is 4. 5 units <u>below</u> the line of best fit.

A graph is said to be formed by plotted points on a <u>Cartesian </u>coordinate plane. When the plotted <em>points</em> are <u>scattered</u>, a <em>line of best fit</em> is required to shoe the relationship among the plotted <em>points</em>.

A <u>residual</u> <u>value</u> is a form of error that is determined from the <em>line of best fit</em>. A <u>line of best fit</u> is a line drawn at <em>average</em> point to a <em>series</em> of plotted <em>scattered</em> points.

Therefore, a residual value of 4.5 with respect to a <em>line of best fit</em> implies that: The data point is 4. 5 units <u>below</u> the <em>line of best fit</em>.

Thus the <em>correct</em> option is B.

Help ya girl out in this math problem!
Levart [38]

The mid segment is half of the base

so

1/2(6x-12)  = 2x + 10

3x  - 6 = 2x + 10  I distributed the 1/2

-2x       -2x          subtract 2x from both sides

x   -6   =  + 10

   +6        +6  Add 6 from both sides

  x    =   16

now we know x is 16 and BE is 2x+10

so I can find it by plugging 16 in

2(16) + 10

32 + 10 = 42  is BE
