what's 3/4 divided by 1 1/5

Answer:

B

Step-by-step explanation:

The probability of getting both fashion and health magazine without replacement is 2/7.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, a shelf contains 3 fashion magazines and 4 health magazines.

Total number of books = 7

Number of fashion magazines = 3

Number of health magazines= 4

Probability of getting fashion magazines = 3/7

Probability of getting health magazines = 4/6

Probability of getting both the events = 3/7 ×4/6

= 1/7 ×4/2

= 2/7

Therefore, probability of getting both fashion and health magazine without replacement is 2/7.

Using the Central Limit Theorem, it is found that the standard error for this sample is of 1.67.

It states that for a population of standard deviation [tex]\sigma[/tex], the sampling distribution of sample means of size n has standard error [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem, we have that [tex]\sigma = 10, n = 36[/tex], hence the standard error is given by:

[tex]s = \frac{10}{\sqrt{36}} = 1.67[/tex]

Step-by-step explanation:

1007.5 because if you do the math, 15.5% of 65:

65 * 15.5% = x

x=1007.5

double check:

1007.5 / 15.5%= 65

triple check:

1007.5 / 65 = 15.5%

Answer:

C

Step-by-step explanation:

Step-by-step explanation:

h=b-4

A=30ft^2

A=1/2bh

30=1/2b(b-h)

Cross Multiply

60=b(b-4)

60=b^2-4b

b^2-4b-60=0

Factorise the equation

(b^2+6) (-10b-60)

b(b+6)-10(b+6)

(b-10) (b+6)

b-10=0 or b+6=0

b=10 or b=-6

base =10 (since measurement can not be negative)

h=b-4

Sub the value of b

h = 10-4

h=6

So the height is 6ft and base is 10ft

INn FOUR hours Jennifer will travel 12 m/h x4 = 48 miles

it will take Thomas 48 miles / 4 m/hr = 12 hours to reach the bike in the meantime Jennifer has EIGHT hours of walking 3 m/hr x 8 = 24 miles form the bike Thomas now sets out at 10 m/h this is 10 - 3 = 7 m/h faster than Jennifer is walking he will close the 24 miles and catch Jennifer in 7 m/hr *x = 24 m

24/7hours

So Thomas walks for 12 hours then bikes for 24/7 hr = 15 3/7 hrs = ~ 15 hr 26 min

Often written as x1,2=4±2√2

The solution of the given quadratic equation by completing the square method are [tex]2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex].

Completing the square method is factorizing a quadratic equation, and henceforth finding the roots or zeros of a quadratic polynomial or a quadratic equation.

According to the given question.

We have a quadratic equation

[tex]3x^{2} + 24x - 24 = 0[/tex]

The above quadratic equation can be written as

[tex]3(x^{2} + 8x - 8) = 0[/tex]

[tex]\implies x^{2} + 8x -8= 0[/tex]

Now, we will solve the above equation by completing the square method.

[tex]x^{2} +8x - 8= 0[/tex]

[tex]\implies x^{2} + 2(4x) +(4)^{2} -(4)^{2} -8 = 0[/tex]

[tex]\implies x^{2} + 2(4x) + 16 - 16 -8 = 0[/tex]

[tex]\implies (x+4)^{2} - 24=0[/tex]

[tex]\implies (x+4)^{2} = 24[/tex]

[tex]\implies (x+4)^{2} = 24[/tex]

[tex]\implies (x+4) = \sqrt{24}[/tex]

[tex]\implies x+ 4 = \pm 2\sqrt{6}[/tex]

[tex]\implies x = 2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex]

Hence, the solution of the given quadratic equation by completing the square method are [tex]2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex].
