An amateur golfer wishes to determine if there is a difference between the drive distances of her two favorite drivers. (A drive

r is a specialized club for driving the golf ball down range.) She hits fourteen balls with driver A and 10 balls with driver B. The drive distances (in yards) for the trials are shown below.
Driver A
282 246 253 302 264 248 275
214 269 283 303 257 233 279
Driver B
249 235 251 269 218
252 220 292 263 239
Assume that the populations are approximately normal. Construct a 90% confidence interval for the difference between the mean drive distances for the two drivers. Be sure to include all necessary steps using an organized approach.

What is the value of x (x+2)(x-3)=0
wolverine [178]

Answer:

x = 3 or x = -2

Step-by-step explanation:

Solve for x over the real numbers:

(x + 2) (x - 3) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

x - 3 = 0 or x + 2 = 0

Hint: | Look at the first equation: Solve for x.

Add 3 to both sides:

x = 3 or x + 2 = 0

Hint: | Look at the second equation: Solve for x.

Subtract 2 from both sides:

Answer: x = 3 or x = -2

What is the value of x?
lorasvet [3.4K]

Answer:

x=9

Step-by-step explanation:

We can use similar triangles and ratios.  Put the small triangle side over the large triangle side.

9cm            3x -20

----------   = ----------------    We need to add the sides to get to the larger triangle

72+9 cm   3x-20 + 56


We can cross multiply to solve

9 * (3x-20+56) = (72+9) * (3x-20)

Simplify

9*(3x+36) = 81*(3x-20)

Distribute

27x +324 = 243x -1620

Subtract 27x from each side

27x-27x +324 = 243x-27x -1620

324 = 216x-1620

Add 1620 to each side

324+1620 = 216x

1944 = 216x

Divide each side by 216

1944/216 = 216x/216

9=x
