Step-by-step explanation:
48+a=63
a=15
Bolts are usually classified in terms of two types of measurements: the metric system and the imperial system. In calipers, the metric system is in units of millimeters, while the imperial system is in units of inches. For example, when a bolt is sized as 12 × 1.25 in the metric system, that means the bolt thread diameter measures 12 mm, and the thread pitch measures 1.25 mm.
So, if your metric bolt measures 0.78 over the threads, that means that the
size of the bolt is 0.78 mm in thread pitch. The attached picture shows how you measure the thread pitch.
Answer:
-13/12
Step-by-step explanation:
75/12-22*4/3*4
75/12-88/12
-13/12
I'll show a step-by-step. I'm not in the mood to explain right now lol.
2(x-2.6)+2.91=7.71
2x-5.2+2.91=7.71
+5.20 +5.20
2x+2.91=12.91
-2.91 -2.91
2x=10
/2 /2
x=5

hope it helps
sorry if it doesn't
A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.
b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score
c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.
d. z = -0.15
The percentile equivalent and the area is equal to 0.44.
