8 × 22 + 52 × 4
176 + 208
384
this will be your answer
i hope this help
Answer:
3/8 CAN ALSO BE WRIITEN AS 375/1000=0.375
SILUTION..
3×125/8×125..
AS WE HAVE TO GET DENOMINATOR IN FORM OF1,10,100,1000,..SO ON.
375/1000
=0.375
Answer:
B: Retain the null hypothesis
Step-by-step explanation:
In the relationship between the confidence interval and hypothesis, it is stated that:
When the confidence interval is constructed, all values that fall inside the interval are considered possible values for the parameter that we are estimating while values that fall outside the interval are rejected as they are considered not possible or realistic values.
Now, If the value of the parameter specified by the null hypothesis falls inside the given confidence interval, then we will fail to reject the null hypothesis at the corresponding significance level. However, If the value specified by the null hypothesis doesn't fall inside the given confidence interval, then the null hypothesis can be rejected at the corresponding significance level.
Remember you can do antying to an equaitn as long as you do it to both sides
treat as equaiton, but flip sign when dividng or muliplying by negaitve
isolate x
first distribute
7+3x<u><</u>8(3+x)
7+3x<u><</u>24+8x
minus 3x both sides
7<u><</u>24+5x
minus 24 both sides
-17<u><</u>5x
divide both sides by 5
-17/5<u><</u>x
