Answer:
5.
Step-by-step explanation:
7x=35; ⇔ x=5.
You can't factor out c or d since we don't know what they are so you have to find an integer. both are divisible by 5, which would become 5(9c+2d). 9 and 2 don't have anything in common so that is it.
45c+10d = 5(9c+2d)
45 square feet
Rectangle: 5*4=20square feet
Parallelogram: 5*2=10square feet
Trapezoid: 4*3=12square feet; 2*3=6 => 6/2=3square feet
20+10+12+3=45square feet
You’re welcome:)
Answer:
C) A one-tail test will be performed since the alternative hypothesis contains a "less than".
Step-by-step explanation:
Test may be categorized as being one tailed or two tailed depending on the inequality sign used when defining the hypothesis ` ; Hypothesis whereby the alternative hypothesis takes a not equal to (≠) are categorized as two talked as the direction of does not point to either the left or right. Conversely, alternative hypothesis which takes a less Than sign or takes a greater Than sign are classed as being one tailed as the they point to a specified direction..
For the scenario given : we are to test the claim that one is stronger than the other ;
For this knid if test it has been stated explicitly that one is greater than another ;
H0 : μ = μ
H0 : μ < μ
The answer is 9. 7 times 9 is 63 and then 63 divided by 3 is 9.
