4(p - 7) = 44
First distribute the 4 over the parentheses
4p - 28 = 44
Add 28 to both sides:-
4p = 44 + 28
4p = 72
Divide both sides by 4:-
p = 72/4
p = 18 (answer)

A farmer was asked how many cows and chickens she has. The farmer replied, "between the cows and the chickens, there are 162 eye
Kazeer [188]
<h2>☀️ <u>Solution</u><u>:</u></h2>

We all know that,

  • All animals have 2 eyes.
  • All cows have 4 feet
  • All hens have 2 feet

So, Let the no. of cows be x and chickens be y

According to question,

  • Total number of eyes = 162

Framing equation,

⇛ Eyes of cows + Eyes of chickens = 162

⇛ 2x + 2y = 162

⇛ 2(x + y) = 162

⇛ x + y = 162/2 = 81 -----------(1)

According to question(Cond.-1)

  • Total number of feet = 270

Framing equation,

⇛ Feet of cows + Feet of chickens = 270

⇛ 4x + 2y = 270

⇛ 2(2x + y) = 270

⇛ 2x + y = 135 ----------(2)

Subtracting eq.(1) from eq.(2),

⇛ 2x + y - (x + y) = 135 - 81

⇛ 2x + y - x - y = 54

⇛ x = 54

Putting value of x in eq.(1),

⇛ 54 + y = 81

⇛ y = 81 - 54

⇛ y = 27

⚘ So, Total number of animals,

  • Number of cows = x = 54
  • Number of chickens = y = 27

Hence, solved !!

In stats would a test looking at gender &amp; holiday preference would I do a Chi-squared test? Which is the explanatory &amp; w
Liula [17]

In statistics, a Chi-squared test may be used to determine holiday choice and gender and α (alpha) is the response variable.

<h3>What is the Chi-squared test? </h3>

A statistical technique called the chi-square test is used to compare actual outcomes with predictions.

The goal of this test is to establish if a discrepancy between actual and predicted data is the result of chance or a correlation between the variables you are researching.

Whether there is a statistically significant association between categorical variables is determined by the Chi-square test of independence.

This issue is addressed by a hypothesis test. The chi-square test of association is another name for this assessment.

Hence,in stats would a test looking at gender & holiday preference yes you can do  a Chi-squared test and α(alpha) is the response variable.

Subtract -5x^2 - 3 from -x - 5
Margarita [4]
      -x-5
  -  -5x^2 - 3

or

(-x-5) - (-5x^2 - 3)

First, distribute the -. So then it becomes

-x - 5 + 5x^2 + 3

Since you can't add 5x^2 to -x. You can only combine -5 and 3.
Thus it becomes
 - x + 5x^2 -2

However, you order in exponents so

5x^2 - x - 2

would be the correct answer.
