Answer:
4d+3
Step-by-step explanation:
Combine the like terms 3d + d which is 4d and 5 - 2 is 3, keep the addition symbol, and you will get 4d+3
Answer:
A- 
Step-by-step explanation:
1.6* 3.2
add the exponents so 10 to the -4
Answer:
Non Proportional
Step-by-step explanation:
Without Solving, this equation contains a y-intercept (6) or b
Proportional relationships start at the origin
Given:
n = 27, sample size
df = n-1 = 26, degrees of freedom
xb = 11.8, sample mean
s = 2.3, sample standard deviation.
Because population statistics are not known, we should use the Student's t-distribution.
At 99% confidence interval, the t-value = 2.779 (from tables).
The confidence interval is
11.8 +/- 2.779*(2.3/√(27)) = 11.8 +/- 1.23 = (10.57, 13.03)
Answer: (10.6, 13.0) to the nearest tenth
Answer:
The third option.
Step-by-step explanation:
Because of the exponent, (the tiny number in the right-hand corner) you have to multiply 5 4 times, which is the same as 5 times 5 times 5 times 5 times 5.
