Answer:
-111
Step-by-step explanation:
substitute 5 in place of each x
-4(5)^2 - 3(5) + 4
then evaluate or type it into your calculator
-100 - 15 + 4
Answer:
x = - 100
Step-by-step explanation:
Given
+ 6 = - 14 ( subtract 6 from both sides )
= - 20
Multiply both sides by 5 to clear the fraction
x = 5 × - 20 = - 100
Answer:
(a) H0:μ1=μ2; Ha:μ1≠μ2, which is a two-tailed test.
Step-by-step explanation:
We formulate the
H0: μ1=μ2; null hypothesis that the two means are equal and alternate hypothesis that the two mean are not equal.
Ha:μ1≠μ2 Two tailed test
Test statistic used is
t= x1`-x2` / s√n as the variances are equal and sample size is same
T value for 9 degrees of freedom for two tailed test at α = 0.05 is 2.26
P- value for t test for 9 degrees of freedom is 0.125 from the table.
Hence only a is correct .
Answer is 24.
firsty remember OF= MULTIPLY
NOW we can calculate this easily
here the equation is given
2/5×60. u can solve this in given ways below….…..
1……….
u can simply divided 60 by 5. which is equal to 12. and now the equation remain 2×12 . & it's equal to 24. which is our answer.
2……….
u can write 2/5 in decimals by dividing this . so 2/5 is equal to 0.4
and now u r left with 0.4×60
so after multiplying it comes 24.0
and that is equal to 24. (because after decimal zeros has no value)
3……….
and u also can multiply 2 by 60 . it occurs 120 then devide it by 5 . the answer comes 24.
