Answer:

576 grams

Step-by-step explanation:

The ratio of sugar to cans is ...

(120 g) : (5 cans) = X/(24 cans)

Multiplying by 24 cans, we find ...

X = (24/5)(120 g) = 576 g

There are 576 grams of sugar in a case of MathJuice.

Step-by-step explanation:

$\huge{\underline{\underbrace{\mathcal\color{gold}{Answer}}}}$

$\tt{3(x-5)+2=29 }$ ⠀

$\tt{3x-15=29-2 }$ ⠀

$\tt{ 3x=27-15 }$ ⠀

$\tt{ 3x=12 }$ ⠀

$\tt{ x=\dfrac{12}{3} }$ ⠀

$\tt{x=4 }$ ⠀

So,

According to the question,

$\tt{ x^2=x×x=4×4=16}$ ⠀

If f(x) = 2х2 +1 and g(x) = х2 -7, find (f-g)(x).

Nookie1986 [14]

Option A

If f(x) = $2x^2 + 1$ and g(x) = $x^2 - 7$ then $(f - g)(x) = x^2 + 8$

<em><u>Solution:</u></em>

Given that f(x) = $2x^2 + 1$ and g(x) = $x^2 - 7$

To find: (f - g)(x)

We know that,

(f – g)(x) = f (x) - g(x)

Let us substitute the given values of f(x) and g(x) in above formula,

$(f - g)(x) = 2x^2 + 1 - (x^2 - 7)$

For solving the brackets in above expression,

There are two simple rules to remember:

When you multiply a negative number by a positive number then the product is always negative.

When you multiply two negative numbers or two positive numbers then the product is always positive.

So the expression becomes,

$(f - g)(x) = 2x^2 + 1 -x^2 + 7$

Combining the like terms,

$(f - g)(x) = 2x^2 - x^2 + 1 + 7\\\\(f - g)(x) = x^2 + 8$

Thus option A is correct

An experiment was conducted as a one-way factorial design with K sample means, each based on n scores. What is the number of deg

nordsb [41]

Answer:

The mean squares has d.f (n-1)

Step-by-step explanation:

The total number of degrees of freedom is n-1 as there is only one restriction of computing the grand mean. The d.f for k samples is k-1 beacuase the mean of the sample means must equal the grand mean. Similarly , the d.f for within SS is n-k , due to the k restrictions of computing the k sample means. Hence we find that

Total df= Within df + Between df

n-1= (n-k)+(k-1)

Between SS has (k-1) d.f

Within SS has (n-k) d.f

These two quantities are known as mean squares and has d.f (n-1)
