Answer:
Area: 5 cm squared
Perimeter: 12 cm
Step-by-step explanation:
The area is Length times Width, and there is 5 different sqaures in the figure.Each sqaure has an area of 1 by 1, which is 1. 1 times 5 is 5. So the area is 5. You can get the perimeter by adding all the side lengths together, 2+3+2+1+1+1+1+1=12. The perimeter is 12. Hope this helps.
Answer:
<em>The</em><em> </em><em>answer is</em><em> </em><em>29</em><em> </em><em>unit</em><em>.</em>
Step-by-step explanation:
Here,
given that,
DC (l) =4z+1
CD (b)=5z+2
perimeter (p)= 132
now,
perimeter of rectangle (p) is= 2(l+b)
or, 132 = 2×{(4z+1)+(5z+2)}
or, 132= 2×(9z+3)
or, 132= 18z+6
or, 18z=132-6
or, z=126/18
or, z= 7.
therefore, 4z+1=4×7+1=29
5z+2= 5×7+2=37.
As our question is about to find AB,
DC = AB. (as opposite side of rectangle is equal).
so, the valueof AB is 29unit.

Easy 4,500 - 750x = y x is the number of months which is the independent variable (yes this is science in math) y which is the dependent variable which is the amount he has after x amount of months Ex: 2= x 4500 - 750 x 2 = 4500 - 1500 = $3,000 left in his account
Answer:
There is not enough evidence to support the mangers claim.
Step-by-step explanation:
We are given;
Sample Size; n = 1600
Sample proportion; p^ = 0.26
Population Proportion; p = 0.24
The hypotheses are;
Null Hypothesis: H0: p = 0.24
Alternative Hypothesis: Ha: p ≠ 0.24
The z-formula for this is;
z = (p^ - p)/√(p(1 - p)/n)
Plugging in the relevant values, we have;
z = (0.26 - 0.24)/√(0.24(1 - 0.24)/1600)
z = 0.02/0.01067707825
z = 1.87
From online p-value from z-score calculator, with 2 tail attached, we have;
p = 0.061484
This p-value is less than the significance level of 0.1. Thus, we will reject the null hypothesis and conclude that there is not enough evidence to support the managers claim.
