6600 in^3

Step-by-step explanation:

vertical rectangular cube:

V= 10x10x30

V=3000

horizontal rectangular cube:

V=30x10x12

V=3600

Suppose that 65% of high school students eat breakfast before going to school. A random sample of 500 high school students were

krok68 [10]

Answer:

1.) very large sample size

2.) 0.11326

3.) np and n(1-p) should be ≥ 10

4.) 0.010809

Step-by-step explanation:

Given :

p = 0.65 ; n = 500

2.)

P(x ≤ 300)

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Using a binomial probability calculator :

P(x ≤ 300) = 0.11326

To justify why if it can be approximated using a normal distributon :

np and n(1-p) should be ≥ 10

np = 500 * 0.65 = 325

n(1-p) = 500(1 - 0.65) = 175

4.) probability using normal distribution estimate:

Mean, m = np = 500 * 0.65 = 325

Standard deviation, s = sqrt(n*p*(1-p)) = sqrt(500*0.65*(1 - 0.65)) = sqrt(113.75) = 10.665

x ≤ 300

Correction:

x = x + 0.5 = 300 - 0.5 = 300.5

P(x ≤ 300.5)

Zscore = (x - m) / s

Zscore = (300.5 - 325) / 10.665

Zscore = - 24.5 / 10.665

Zscore = - 2.297

P(Z ≤ - 2.297) = 0.010809

Someone pllss help me

dusya [7]

Answer:

I= 1,600

B= 9,600

Step-by-step explanation:

Interest is 8,000 x 0.04(4%) x 5

when you multiply all three (PRT) you end up with 1,600 as your interest.

then your balance is when you add the original borrowed amount ($8,000) with your interest ($1,600).

8,000+1,600= 9,600

Brian invests £1800 into his bank account.

SVEN [57.7K]

Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

Principal ( P ) = £ 1800
Rate ( R ) = 5%
Time ( T ) = 3 years

$\underline{ \underline{ \text{To \: find}}} :$

Total amount

$\underline{ \underline{ \text{Solution}}}:$

First , finding the amount of interest :

$\boxed{ \sf{Interest = \frac{PTR}{100}}}$

⇢ $\sf{Interest = \frac{1800 \times 5 \times 3}{100}}$

⇢ $\sf{Interest = \frac{27000}{100}}$

⇢ $\sf{Interest = £ 270}$

Now , Finding the total amount :

$\boxed {\sf{Total \: amount = Principal + Interest}}$

⇢ $\sf{Total \: amount = 1800 + 270}$

⇢ $\sf{Total \: amount = \: £ 2070}$

$\red{\boxed{ \boxed{ \tt{Our \: final \: answer : brian \: will \: have £ 2070 \: after \: 3 \: year.}}}}$
