Answer:
1. 10d + 26
Step-by-step explanation:
Given.
8(2d+3) + 2(-3d+1)
= 16d + 24 - 6d + 2
= 10d + 26
Hope it will help :)
Answer:
67
Step-by-step explanation:
To round 67.498 to the nearest whole number consider the tenths’ value of 67.498, which is 4 and less than 5. Therefore, we have to round down: the whole number ones place value of 67.498, 67, remains 67, and the decimal point and all digits (.498) are removed.
67.498 rounded to the nearest whole number = 67
Answer:
17°
Step-by-step explanation:
Look everything you have above the horizontal line.
It's a 73° angle, plus the one you need, plus 90°. They add up to 180.
m+73+90=180, or m=17.
<u>Answer:</u>
The hand moved 
of a complete turn.
<u>Step-by-step explanation:</u>
The hand moved from 3 to 12, that is, it moved:
12 - 3 = 9 hours
In a clock, 12 hours represent a complete turn.
∴ Using the unitary method:
12 hours ⇒ 1 turn
1 hour ⇒ 
turns
9 hours ⇒ × 9 = 
= turns (simplified)
∴ The hand moved of a complete turn.
The distribution is not a standard normal distribution.
We know that the variable (X) usually obeys and follows a standard normal distribution provided that the summation of (X) is zero and the variance of the random variable V(X) = 1.
Mathematically:
E(X) = 0 and V(X) = 1
Given that;
- the mean which follows a normal distribution (X) = 4.5338 g, and
- the standard deviation SD(X) = 0.1039 g
As such, the distribution is not a standard normal distribution.
Therefore, we can conclude that the distribution is not a standard normal distribution.
