Emma had 10 Balls in a bag. The balls were numbers 1 through 10. She wanted to test the probability of drawing a ball that is a

multiple of 3.
Also, write a prediction about if there is an unlikely, impossible, likely, even, or certain change of drawing a multiple of 3.

Answer:

  • 30%
  • Unlikely

Step-by-step explanation:

<u>The balls - multiples of 3 are:</u>

  • 3, 6 and 9

<u>The probability of a multiple of 3 is:</u>

  • 3 out of 10 or
  • P = 3/10 = 30%

30% probability is in the range 0%-50% so this event is unlikely

  • Total balls=10
  • Multiples of 3=3,6,9

Total multiples=3

\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}

\\ \sf\longmapsto P(3)=\dfrac{3}{10}

\\ \sf\longmapsto P(3)=30\%

  • It is <50%;

So it is unlikely to happen.

Simplify (3x − 5) − (4x + 6).
irinina [24]

(3x − 5) − (4x + 6)

Pretend that there is a 1 in front of the first bracket.

Pretend that there is a -1 in front of the second bracket.

Multiply the first bracket by 1

(1)(3x)=3x, (1)(-5)=-5

Multiply the second bracket by -1

(-1)(4)=-4, (-1)(6)=-6

3x-5-4x-6

3x-4x-5-6 ( combine like terms)

-x-11

Answer: -x-11 or -11-x

PLS HELP! If f(x) = -9x + 12, and f(x) = -6, find x.
aivan3 [116]

Answer:

2

Step-by-step explanation:

You can rewrite thosee two equations as -9x+12=-6, because f(x)=f(x)

Now isolate x

-9x+12=-6

-9x+12-12=-6-12 (subtract 12, subtraction property of equality)

-9x=-6-12

-9x=-18 (simplify)

-9x/-9=-18/-9 (divide by 9, division property of equality)

x=2

15. What might explain the concern female students expressed in the beginning of this lesson about the problem of assigning prac
yanalaym [24]

Answer:

Interestingly, the likelihood of a randomly chosen student being a female is <u><em>0.58</em></u> at this school.

Step-by-step explanation:

This school features more female students than male students. <em>Consequently, if resources are allocated equally (because it has been found that both female and male male students are similarly likely to be involved), the number of female students involved in after-school athletics programs is greater than the number of male students and could clarify the facilities issues.</em>

What is the area of FGH
Dmitrij [34]
54 in^{2}

A right triangle is a shape that looks like half of a square. The height of the triangle is 12, and the base of the triangle is 9. To find the area, use the following formula: 

A = \frac{bh}{2}


= \frac{12x9}{2}


= \frac{108}{2}


= 54 in^{2}

Does the following picture represent a linear function?
nekit [7.7K]

Answer: No

Step-by-step explanation: For x 0-2, the y is increasing by +5 every time. However, the moment it hits x=2, it starts decreasing by -5 every time. This means that it does not follow on set pattern (either +5 or -5) and looks more like a ^ than a /.
