If he hits the target 95% of the time, then you could say that he has a probability of 0.95, or 95% of hitting the target. Let p = the probability of hitting the target or p = 0.95. So you are interested that he misses the target at least once - this could be thought of as not getting a perfect score. So to get a perfect score, it is 0.95 for each target -- 0.95^15 for 15 targets is 0.464. Thus to miss at least one target he needs to NOT have a perfect score -- 1 - 0.464 = 0.536, or 53.6% of happening. Enjoy

Find the area of the figure shown. Use 3.14 to approximate pi
Nina [5.8K]
Alrighty

we gots 1/4 circle and paralellogram

area circle=pi times radius^2
area paralelogram=base times height


1/4 circle is
radius is 10 so
area part circle is 1/4 times pi times 10^2=100/4pi=25pi=78.5 m²

area paralllogram is
10 times 3 because 3 is height and 10 is base length or 30

30+78.5=108.5 m² is the area

Can someone please help with the last problem
Brut [27]

Answer:

  18x +9h

Step-by-step explanation:

Such problems are tedious, but not difficult. The trick is to avoid making mistakes in the algebra.

  \dfrac{f(x+h)-f(x)}{h}=\dfrac{(9(x+h)^2)-(9x^2)}{h}\\\\=\dfrac{9(x^2+2xh+h^2)-9x^2}{h}=\dfrac{18xh+9h^2}{h}=\boxed{18x+9h}

#13. 6x — Зу = 8
Ne4ueva [31]

#13

  • 6x — Зу = 8
  • 3y = 6x - 8
  • y = 6/3x - 8/3
  • y = 2x - 8/3
  • The slope = 2
  • The y- intercept = - 8/3

#14

  • 7x = 5y + 2
  • 5y = 7x - 2
  • y = 7/5x - 2/5
  • y = 1.4x - 0.4
  • The slope = 1.4
  • The y- intercept = - 0.4

#15

  • - 6у + 4х = 8
  • 6y = 4x - 8
  • y = 4/6x - 8/6
  • y = 2/3x - 4/3
  • The slope = 2/3
  • The y- intercept = -4/3

#16 is not clear
