Answer:
x=2.17 
Step-by-step explanation:
 +18x+81=-4
 +18x+81=-4
             -81  -81
 +18x= -85
 +18x= -85
     /18       /18 
 = -4.7
= -4.7
 =
= 
x= 2.17
I hope this helps :) (if it does, brainliest, please??)

Answer:
Step-by-step explanation:
pop 1 n₁ = 260, p₁ = 58% = 0.58
pop 2 n₂ = 260, p₂ = 8% = 0.08
Null hypothesis: p₁ ≤ p₂
Alternative hypothesis: p₁ > p₂
The test statistic : p₁-p₂ / √{p-sample (1 - p-sample) (1/n₁ + 1/n₂)}
where p-sample is sample proportion = p₁n₁ +p₂n₂ / n₁+n₂
Thus, p-sample = 0.58x260 +0.08x260 / 260+260 =150.8+20.8 / 520 = 171.6 / 520 = 0.33.
Thus, the test statistic is (0.58 - 0.08) / √[0.33 (1-0.33) (0.0038+0.0038) 
   = 0.5 / √[0.33(0.67) (0.0076)
= 0.5 / √0.00168036
 = 0.5 / 0.04099
= 12.20
P = P(Z>12.20) = 1-P(Z≤12.20) at a significance level of 0.1= the p-value is less than the hypothesized thus, we have sufficient evidence to reject the null hypothesis and concluding that vinyl gloves have a greater virus leak than latex gloves.
 
        
             
        
        
        
Answer:
6
Step-by-step explanation:
10/5 ×/3 multiply 10×3 and than divide by 5 
or another way start with multiplying 5 and n equaling 5n= 
than 10× 3= 30 so you're left with 5n=30 divied 30 by 5 equalling 6
so x=6 
 
        
             
        
        
        
Answer:
y = 6x
Step-by-step explanation:
The equation representing a proportional relationship is
y = kx ← k is the constant pf proportionality
Here k = 6 , then
y = 6x ← equation of proportion
