1/4 +1/3 divided by4/5

Mathematics
1 answer:
ad-work [718]3 years ago
7 0

Answer:

2/3

Step-by-step explanation:

Do 1/3 divided by 4/5 first.

So we are going to flip 4/5 to 5/4. The equation is now:

1/4+1/3 times 5/4

Now we are going to do the multiplication since multiply and division is before adding and subtraction.

1/3 times 5/4 = 5/12

Now we have to add 1/4+5/12

With adding ( and subtracting) we have to find the common denominator which is 12

So now we have 3/12 + 5/12 = 8/12 which reduces to 2/3

What are the solutions to the nonlinear system of equations below?
Sonbull [250]
Substitute y=4x to the second equation:

x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1

When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4

Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.

If the level of significance of a hypothesis test is raised from 0.005 to 0.2, the probability of a type ii error will:_________
LiRa [457]

The probability of type II error will decrease if the level of significance of a hypothesis test is raised from 0.005 to 0.2.

<h3 /><h3>What is a type II error?</h3>

A type II error occurs when a false null hypothesis is not rejected or a true alternative hypothesis is mistakenly rejected.

It is denoted by 'β'. The power of the hypothesis is given by '1 - β'.

<h3>How the type II error is related to the significance level?</h3>

The relation between type II error and the significance level(α):

  • The higher values of significance level make it easier to reject the null hypothesis. So, the probability of type II error decreases.
  • The lower values of significance level make it fail to reject a false null hypothesis. So, the probability of type II error increases.
  • Thus, if the significance level increases, the type II error decreases and vice-versa.

From this, it is known that when the significance level of the given hypothesis test is raised from 0.005 to 0.2, the probability of type II error will decrease.

What is the equation of the line (-2,-3) (4,5)
sleet_krkn [62]
Slope = m = y2-y1/x2-x1
 = 5-(-3)/4-(-2)
m=8/6
m=4/3
so  eq of line we select any of one point . i select (4,5)
y - y1 = m(x-x1)
y- 5 = 4/3 (x-4)
3y -15 = 4x-16
4x-3y = 1

the base of a triangle is 5/8. The height is 1/3 feet. how much greater is base of the triangle than the height?
maks197457 [2]
Namely, how many times does 1/3 go into 5/8?  well, is their quotient,

\bf \cfrac{\quad \frac{5}{8}\quad }{\frac{1}{3}}\implies \cfrac{5}{8}\cdot \cfrac{3}{1}\implies \cfrac{15}{8}\implies 1\frac{7}{8}

Make x the subject:<br>y= (x+10)^2​
Elis [28]

Answer:

x = - 10 ± \sqrt{y}

Step-by-step explanation:

y = (x + 10)² , or

(x + 10)² = y ( take square root of both sides )

x + 10 = ± \sqrt{y} ( subtract 10 from both sides )

x = - 10 ± \sqrt{y}
