Answer:

4/10 = 2/5

Step-by-step explanation:

It's asking you what's an equivalent fraction to 4/10. 4/10 is equivalent to 2/5 because the size of 2 parts out of 5 is the same size as 4 parts out of 10.

Factor out the GCF 45c^6+20c^4

tatiyna

Answer:

5c^4( 9c^2 + 4).

Step-by-step explanation:

The GCF of 45 and 20 is 5 and the GCF of c^6 and c^4 = c^4.

So the GCF is 5c^4 and the factors are:

5c^4( 9c^2 + 4)

Bill is making a garden that is twice as long as it is wide.

Cloud [144]

Answer:

The equation that best represent the situation is;

x^2 = 576

or x^2 -576 = 0

Step-by-step explanation:

Here, we want an equation that best represent the given information in the question.

The length of the garden is twice as long as it is wide

So, given that x is the length of the garden, then x/2 will represent the width of the garden

From the description given in the question, the garden would be rectangular in shape.

Mathematically, the area of a rectangle can be calculated using the formula;

L * B = area

Thus;

x * x/2 = 288

x*2 = 2 * 288

x^2 = 576

After an extensive advertising campaign, the manager of a company expects the proportion of potential customers that recognize a

lina2011 [118]

Answer:

Step-by-step explanation:

Hello!

The study variable is:

X: number of customers that recognize a new product out of 120.

There are two possible recordable outcomes for this variable, the customer can either "recognize the new product" or " don't recognize the new product". The number of trials is fixed, assuming that each customer is independent of the others and the probability of success is the same for all customers, p= 0.6, then we can say this variable has a binomial distribution.

The sample proportion obtained is:

p'= 54/120= 0.45

Considering that the sample size is large enough (n≥30) you can apply the Central Limit Theorem and approximate the distribution of the sample proportion to normal: p' ≈ N(p; $\sqrt{\frac{p(1-p)}{n} }$ )

The other conditions for this approximation are also met: (n*p)≥5 and (n*q)≥5

The probability of getting the calculated sample proportion, or lower is:

P(X≤0.45)= P(Z≤ $\frac{0.45-0.6}{\sqrt{\frac{0.6*0.4}{120} } }$ )= P(Z≤-3.35)= 0.000

This type of problem is for the sample proportion.

I hope this helps!
