Find g(x)-f(x) if f(x)=-3+4 and g(x)=5x-12
Verizon [17]

Answer: g(x)-f(x)=8x-16

Explanation:

f(x)=-3x+4  (I am assuming "-3+4" is a typo and it is "-3x+4")

g(x)=5x-12

g(x)-f(x)=(5x-12)-(-3x+4)=5x+3x-12-4=8x-16

Aneesha travels at 50 mph. Morris is traveling at 3 feet per second less than Aneesha. How fast is Morris traveling
vampirchik [111]

Speed of Morris is 47.95 mph

Step-by-step explanation:

  • Step 1: Convert 3 feet per second to miles per hour.

⇒ 3 ft/s = 3/1.467 mph (∵ 1 mph = 1.467 ft/s)

             = 2.05 mph

  • Step 2: Find the speed of Morris.

Speed of Morris = 50 mph - 2.05 mph = 47.95 mph

A production process produces 2% defective parts. a sample of 5 parts from the production is selected. what is the probability t
Lana71 [14]

Answer:

Probability of a sample that contains exactly two defective parts is .0037 or .37%

Step-by-step explanation:

As we know if P is the probability of achieving k results in n trials then probability formula is P = \binom{n}{k}p^{K}q^{n-k}

In this formula n = number of trials

                        k = number of success

                        (n-k) = number of failures

                         p = probability of success in one trial

                         q = (1-p) = probability of failure in one trial

In this sum n = 5

                  k = 2

number failures (n-k) = (5-2) = 3

                            p = 2% which can be written as .02

                            q = 98% Which can be written as .98

Now putting these values in the formula

                        P = \binom{5}{2}(.02)^{2}(.98)^{5-2}

                        P = \binom{5}{2}(.02)^{2}(.98)^{3}

                   \binom{5}{2}= 5!/3!2!    

                                              = 5×4×3×2×1/3×2×1×2×1

                                              = 5×2 =10

                                       P = 10×(.02)²×(.98)³

                                          = .0037 or .37%
