Mathematics
1 answer:
DerKrebs [107]3 years ago
8 0
Start out by combining LIKE TERMS 
5h-2+9h 
in this case 9h and 5h are like terms so you would add both of those together.
9h+5h=14h
-2 has no like terms so we can't do anything with it our final answer would be:
14h-2

Anyone who plays or watches sports has heard of the "home field advantage." Teams tend to win more often when they play at home.
AveGali [126]

Answer:

H0 : μ = 0.5

H0 : μ > 0.5

Kindly check explanation

Step-by-step explanation:

H0 : μ = 0.5

H0 : μ > 0.5

We perform a right tailed test :

Sample proportion :

Number of games won, x = 142

Number of games, n = 250

phat = x / n = 142 / 250 = 0.568 = 56.8%

Yes, it is consistent

Test statistic :

(phat - p) * √Phat(1-Phat)/n

1 -Phat = 1 -0.568 = 0.432

(0.568 - 0.5) /√(0.568*0.432)/250

0.068 / 0.0313289

= 2.17

The Pvalue using the z test statistic :

Pvalue = 0.015

α = 0.03

Since ;

Pvalue < α ; We reject the null and conclude that teams tend to win more often when they play at home.

Sofia takes 10mg of a medicine whose concentration in blood decreases by a factor of one half every day. Let t be the number of
bazaltina [42]

Answer:  Medication in Lexi's system on day t becomes,

L=10.625(\frac{1}{2})^{t-4}

Step-by-step explanation:

Since we have given that

Initial amount Sofia takes of a medicine = 10 mg

Concentration in blood decreases by a factor of one half every day.

So, it becomes,

S=10(\frac{1}{2})^t\\\\here,\text{ t denotes number of days}

According to question, four days later, it becomes,

S=10(\frac{1}{2})^4\\\\S=\frac{10}{16}\\\\S=0.625\ mg

We have given that Lexi takes 10 mg of the same medicine.

So, it becomes,

10+0.625\\\\10.625\ mg

Hence, Medication in Lexi's system on day t becomes,

L=10.625(\frac{1}{2})^{t-4}
