Answer:
c
Step-by-step explanation:
when you add the same number to the previous number it forms a straight line
In order to find height (h), tan20 = h/26

Now for the left part of base (b1), where b2 = 26 and entire base (b) = b1+b2

So b = 13.03+26 = 39.03
Now Area (A) = 1/2bh = 1/2 (39.03)(9.46)
A = 184.59
Answer:
Step-by-step explanation:
Let X represent for males and Y for females
Given that
Group Group One Group Two
Mean 84.00 78.00
SD 4.00 8.00
SEM 1.26 2.53
N 10 10
SEM is calculated as
for each group

(Two tailed test at 5% significance level)

Since p <0.05 we reject H0 and there is significant difference between the groups.
A.Exam scores were significantly higher in the male group, t(18) = 2.83, p < .05B
Answer:
<h3>0.063</h3><h2>
Step-by-step explanation:</h2>
<h3>probability is defined as the measure of chances of events happening or chances of occurrence.The probability that an event can happen is zero(0)</h3><h3>Probability can be calculated using the formular: number of required outcome all over number of total possible outcome.</h3>
Probability of 3 red = 7/16 x 6/15 x 5/14 = (7)(6)(5)/(16)(15)(14)=
6x5/16x15x2 = 5/16x5= 1/16 = (1/2)(.125) = 0.0625
Probability of 3 reds = 0.0625
round off to thousandths Pr(3R) = 0.063
