Congruence by ASA (Angle-Side-Angle): Triangles are congruent if any two angles and their included side are equal in the triangles.
For the given triangles:
Answer:
Dave is 27. His brother is 18.
Step-by-step explanation:
Dave is 9 years older than his brother, so if his brother is 18, he is 27. If you doubled the brother's age (18) you would get 36. Then you subtract 36 by 9 and get 27. <3
Answer:
H0 : μ1 - μ2 = 0
H1: : μ1 - μ2 ≠ 0
we reject the Null and we conclude that babies prefer actual speaking to humming.
Step-by-step explanation:
H0 : μ1 - μ2 = 0
H1: : μ1 - μ2 ≠ 0
Mean difference, d = 27.79
Standard deviation of difference, Sd = 63.18
Sample size, n = 50
The test statistic :
d / (Sd / √n)
Test statistic :
27.79 / (63.18 / √50)
27.79 / 8.9350012
= 3.11
Using the Test statistic score, we can obtain the Pvalue
Using the standard normal table ;
Pvalue = P(x<-Z or x>Z) = 0.0018709
Pvalue is very low
Pvalue < α ; Hence, we reject the Null and we conclude that babies prefer actual speaking to humming.
Answer:
The slope -intercept form of the equation is;
y =
x + 4
Step-by-step explanation:
The slope-intercept form of an equation is;
y = mx + c
where m is the slope and c represent the intercept
To represent the equation given; 3x - 2y = -8 in its slope intercept form, we will follow the steps below:
3x - 2y = -8
subtract 3x from both-side of the equation
3x - 3x -2y = -3x - 8
-2y = -3x -8
Divide throught the equation by -2
-2y/-2 =-3x/-2 -8/-2
y =
x + 4
The slope -intercept form of the equation is;
y =
x + 4
Answer:
x = -3
y = 7
Step-by-step explanation:
y = -2x + 1
7 = -2x + 1
<u>-1 -1 </u>
6 = -2x
divide by -2
x = -3
