A machine produces bolts with a mean diameter of 0.30 inches and a standard deviation of 0.01 inches. The diameters are approxim

ately normally distributed. What is the probability that a randomly selected bolt with a diameter less than 0.32 inches? round to the nearest tenth.

Mean = 0.30
Standard deviation = 0.01
X<0.32?

Using the formula, you get that Z=(0.32-0.30)/4.5 and Z=0.004

Find this value on your table (0.5000)

Then you have that P(X<0.32)= 0.5000

Answer:

C)

Step-by-step explanation:

If you take a look at each of the divided lines, 4 out of the 5 segments are filled, representing 4/5. Since there are 6 of lines, the answer is 6\times \dfrac{4}{5}, or choice C. Hope this helps!

We just need to substitute in 6 whether we see an x:

(7*6) - 4*(6-6) + 12
= 42 - 4*0 + 12

50Pts guys!!!! Please help me its easy!

Answer:

c. f(x)=x(x+2)(x-1)(x-4)

Step-by-step explanation:

Where it says "as x goes to negative infinity" then "y goes to infinity" (that's the part with the infinity symbols) that means the graph is going up at it's left end. This curve is a quartic (4th degree) which means its left and right ends are kind of parabola-ish, but the middle is not the neat u-ish, v-ish shape of a parabola; it's more like a wonky, noodle-ish wavy affair. Anyway, LIKE a parabola when the beginning of the equation is positive, the two ends point up. That's what's happening here and so we can eliminate b. and d. as potential answers.

Since -2, 0, 1, 4 are zeros (which are solutions...and also x-intercepts) we can find the factors of the function.

If x = -2

ADD 2 to both sides.

x + 2 = 0

This means (x+2) is a factor.

This is enough info to select answer c. but let's verify the other factors.

If x = 1

SUBTRACT 1 from both sides.

x - 1 = 0

Thus means (x - 1) is a factor.

If x = 4

SUBTRACT 4 from both sides.

x - 4 = 0

(x - 4) is a factor.

You can see c. has all these factors as well as x, because x=0 already, so x is a factor too.

I think of this as a working backwards problem, bc usually you have to factor and solve. This one, you have solutions (which are zeros and x-intercepts) and work backwards to find factors and multiply them together to find the function.
