Answer:
they need 4 buses
60+60+60=180 that does not get you to 196 so you would add 1 more bus
which equals 4 buses
Answer:
the correct answer is 8 units just took the test
Answer:
Step-by-step explanation:
Let X be the diameter of bolts produced in a machine shop
X is normal with mean = 6.46 mm and std dev = 0.05 mm.
We are to find the two diameters that separate the top 9% and the bottom 9%.
We can use std normal distribution value for this and from Z we can calculate X values
P(Z<z) = 0.09 and P(Z<z1) = 0.91
z=-1.341 and z1 = +1.341
Corresponding X values would be
for bottom 9%
X = 6.46-1.341*0.05 = 6.39295
X = 6.46+1.341*0.05=6.52305
(x+3)(x+4) is the answer if you’re factoring
Answer:
5x - 63 = 6
Step-by-step explanation:
Okay, first step, let's get all fractions having a common denominator, to do this, multiply 2/3 by 3 to get 6/9. Now, we have 5/9x-7=6/9. To make these into whole numbers, we can multiply the whole equation by the denominator (9). 5/9x multiplied by 9 is 5. 7 multiplied by 9 is 63. 6/9 multiplied by 9 is 6. Now we have 5x-63=6. If I were to simplify the equation, it would require decimals, so I'll leave it at this, but the equation simplified is x=13.8.
