Answer:

P(E\ or\ F) = 0.60

Step-by-step explanation:

Given

P(E) = 0.25

P(F) = 0.40

P(E\ and\ F) = 0.05

Required

Determine P(E or F)

This is calculated using:

P(E\ or\ F) = P(E) + P(F) - P(E\ and\ F)

P(E\ or\ F) = 0.25 + 0.40 - 0.05

P(E\ or\ F) = 0.60

On a number line, A is at 5 and B is at 50. Point X is the midpoint. Point T is 2/3 of the way from X to B. Determine the coordi
Lemur [1.5K]

Number lines are used to represent points at regular interval.

The coordinate of point T on the number line is: 46.5

Given that:

A =5

B = 50

The coordinate of X at the midpoint is:

X = \frac{B + A}{2}

So, we have:

X = \frac{50+5}{2}

X = \frac{55}{2}

X = 27.5

Point T is at 2/3 from X to B.

The coordinate of T is calculated using:

T = X + \frac 23 (B - X + 1)

So, we have:

T = 27.5 + \frac 23 (55 - 27.5 + 1)

T = 27.5 + \frac 23 (28.5)

T = 27.5 + 19

T = 46.5

<em>Hence, T is located at 46.5</em>

Sindrei [870]

<u>Answer:</u>

  • 2n + 12 = 100 (Equation)
  • 2n = 88 (Solving)
  • n = 44 people bought muffins at the bake sale. (Solving)

<u>Step-by-step explanation:</u>

  • 100 muffins, and 2 in each package. Therefore, there are 50 packages. However, in the end, there are 12 left, so there must have been 6 packages left.
