Answer: See explanation
Step-by-step explanation:
I think your question should be a rectangle and not a triangle. A triangle has 3 sides and not 2 sides. In order to solve the question, I'm assuming that you wanted to write rectangle.
Note that the perimeter of a rectangle:.= 2(length + breadth)
Let the width be x
Since the length is 1 1/8 cm longer than the width, therefore, the length is 1 1/8 + x.
Therefore, perimeter = 2(1 1/8 + x + x) = 13 1/4
2(1 1/8 + 2x) = 13 1/4
2 2/8 + 4x = 13 1/4
2 1/4 + 4x = 13 1/4
4x = 13 1/4 - 2 1/4
4x = 11
x = 11/4
x = 2 3/4
Therefore, the width is 2 3/4cm
Length = 2 3/4 + 1 1/8
= 2 6/8 + 1 1/8
= 3 7/8cm
Area is 9 and the and the circumstances and 19
Answer: y = 2x + 8
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
Looking at the given line,
y = 2x + 7
Comparing with the slope intercept equation,
Slope, m = 2
If a line is parallel to another line, it means that both lines have equal or the same slope. This means that the slope of the line passing through the point (-2, 4) is 2
Substituting m= 2, y = 4 and x = -2 into the equation, y = mx + c , it becomes
4 = 2 × - 2 + c
4 = - 4 + c
c = 4 + 4 = 8
The equation becomes
y = 2x + 8
Answer: Binomial distribution
Step-by-step explanation:
The binomial appropriation is a likelihood circulation that sums up the probability that a worth will take one of two free qualities under a given arrangement of boundaries or suspicions. The hidden suspicions of the binomial dispersion are that there is just a single result for every preliminary, that every preliminary has a similar likelihood of achievement, and that every preliminary is totally unrelated, or autonomous of one another.
Answer:
z<-2 or z<1
Step-by-step explanation:
The compound inequality to be solved is
5z+3<-7 or -2z-6>-8
Simplifying we get,
z<-2 or z<1
NB: the inequality sign at the right side of or has changed because we have divided through by -2
