Answer:
-15X^3y^2Z^2 is the answer
Answer:
1st Picture: m∠RPS= 15° m∠QPR=25°
2nd Picture: x= 53°
Step-by-step explanation:
1st Picture:
8x+7+9x+16=40
17x+23=40
17x=40-23
17x=17
x=1
Substitute the x values with 1 and solve.
Answer:
1 hot dog costs $3.50
Step-by-step explanation:
Represent Hot dog with x and Hamburger with y
Gregory's purchase:
--- (1)
Hart's purchase:
---- (2)
Required
Find x
To do this, we'll make use of the elimination method of solving simultaneous equation.
Start by multiplying (1) by 2
2 * ()
This gives:
---- (3)
Subtract (2) from (3)
- ()
-------------------------
Solve for x
Hence:
1 hot dog costs $3.50
Number of possible outcomes in the first blank and the second blank is number of winners
Answer:
We do not reject the null
Step-by-step explanation:
Given that :
Sample size, n = 41
Test statistic ; Zstatistic ;= 1.53
Critical value ; Zcritical ; = 2.57
The null hypothesis H0 ;
H0: μ1 - μ2 = 0
Alternative hypothesis, H1 ;
H1: μ1 ≠ μ2
Decision region :
Reject Null ; if |Zstatistic ≥ Zcritical|
Zstatistic > Zcritical
Result :
1.53 < 2.57
Zstatistic < Zcritical
Hence, we do not reject the null ; there is no significant evidence that there is difference in the average yield of the two samples.
