What percent of the model is shaded green?
Answer:
1/5%
Step-by-step explanation:
The percentage of the model shaded green will be 20.
How to find how much percent 'a' is of 'b'?Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
The total number of the box in the figure is 100.
The total number of shaded green = 20
So,
[tex]\dfrac{20}{100} \times 100[/tex]
20%
Therefore, The percentage of the model shaded green will be 20.

Answer:
13u√2u
Step-by-step explanation:
Remark
Removing factors from under the square root sign means factoring the numbers into prime factors. If there are an even number of equal prime factors, take one out and throw one away for all the primes that are the same. An odd number of factors always leaves 1 under the root sign.
For example
u^3 = u * u * u
One of the u's will be left behind. Of the two others, one will be discarded and one will be taken outside the root sign.
√u^3 = √(u * u * u) = u√u
one u taken out. 1 u left behind 1 u discarded.Question Breakdown
8√72u^3 = 8√2*2*2*3*3 u^3 = 8* 2*3 * u * √2u = 48u*√2u7√128u^3 = 7√(2*2*2*2*2*2*2 u^3) = 7*2*2*2 √2u = 56u√2u3u*√98u = 3u * √(7*7 * 2*u) = 21u√2uAnswer

Step-by-step explanation:
The computation of the third quartile is given below:
The third quartile Q3 is
= 3(n + 1)÷ 4
= 3 (24 + 1) ÷ 4
= 75 ÷ 4
= 18.75th term
Now the 18.75th term is
= 18th term + 0.75 term
= 57 + (19 term - 18term)
= 57 + 0.75 (61 - 57)
= 57 + 0.75 (4)
= 60
A bottled water distributor wants to determine whether the mean amount of water contained inâ 1-gallon bottles purchased from a nationally known water bottling company is actually 1 gallon. You know from the water bottling company specifications that the standard deviation of the amount of water is 0.008 gallon. You select a random sample of 50 bottles, and the mean amount of water perâ 1-gallon bottle is 0.995 gallon.
Required:
a. Is there evidence that the mean amount is different from 1.0 gallon?
b. What is the test statistic?
c. Compute theâ p-value and interpret its meaning.
d. Construct a 95% confidence interval estimate of the population mean amount of water perâ 1-gallon bottle.
Answer:
1. There is evidence that mean is different from 1.0 gallon
2. test statistic = -4.42
3. p value = 0.00001
4. 0.9928,0.9972
Step-by-step explanation:
h0: u = 1.0
h1: u not equal to 1.0
alpha = 0.05
sd = 0.008
n = 50
mean = 0.995
standard error se = 0.008/√50 = 0.00113
test statistics calculation
0.995-1/0.00113
= -0.005/0.00113
= -4.42
p value calculation
using the z test statistics and alpha = 0.05
the p value using a p value calculator = 0.00001
0.00001<0.05
so we Reject the null hypothesis
we conclude there is enough evidence that mean is different from 1.0
95% confidence interval
Z alpha/2 = 0.025
we find z value using excel function
NORMSINV (0.025)
|Z| = 1.96
Standard error se = 0.00113
margin of error E = 1.96 x 0.00113 = 0.0022148
confidence interval =
0.995 - 0.0022148, 0.995 + 0.0022148
= 0.9928, 0.9972

Step-by-step explanation:
Rearrange Terms
(-3i+4)(1+2i)
(-3i+4)(2i+1)
Distribute
-3(2i+1)+4(2i+1)
-6i^2-3i+4(2i+1)
-6i^2-3i+4(2i+1)
-6i^2-3i+8i+4
Combine Liker Terms
-6i^2+5i+4
Solution
-6i^2+5i+4
Answer:
-2 + 5i
Step-by-step explanation:
Remember these rules:
real times real = real (e. g., 4(1) = 4)
real times imaginary: imaginary (e. g., 4(2i) = 8i)
imaginary times real imaginary
imaginary times imaginary: real with a negative sign (e. g., (-3i)(2i) = +6
Once again: work out (-3i)(2i). We get (i^2)(-6) = +6
In summary: your (4-3i)(1+2i) becomes 4 + 8i - 3i - (i^2)(-6), or
4 + 5i - 6, or -2 + 5i

C.
8,42
D.

La desviación estándar se puede calcular mediante la fórmula
S = √∑fx² / n - (∑fx / n) ²
La desviación estándar es 6,12
Poner los valores de la tabla en la hoja de Excel dada.
s = √381430 / 60 - (4770/60) ²
s = √6357.167 -6320.25
s = √36,917
s = 6,0759
Cuando se redondea daría 6,1
The standard deviation can be calculated using the formula
S= √∑fx²/n - (∑fx/n)²
The standard deviation is 6.12
Putting the values from the table in the given excel sheet.
s= √381430/60 - (4770/60)²
s= √6357.167 -6320.25
s= √36.917
s= 6.0759
When rounded would give 6.1

What is Pythagoras theorem?Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.
Given: breadth = 3.6, diagonal= 7.4
Using Pythagoras theorem,
H²=P²+B²
(7.4)²= (3.6)²+B²
54.76=12.96 + B²
54.76-12.96=B²
41.8= B²
B= 6.46 inch.
Hence, the value of x is 6.46 inch.

A random sample of 146 recent donations at a certain blood bank reveals that 81 were type A blood. Does this suggest that the actual percentage of type A donations differs from 40%, the percentage of the population having type A blood
Answer:
We reject H₀ the actual percentage of type A donations differs from 40%
Step-by-step explanation:
Sample information:
sample size n = 146
Type A x₁ = 81 and p₁ = 81 / 146 p₁ = 0,5547
then q₁ = 1 - p₁ q₁ = 1 - 0,5547 q₁ = 0,4453
We choose as significance level α = 5% α = 0,05 α /2 = 0,025
from z-table we find z (c) = 1,96
National % of the population ( μ = 40 % μ = 0,4 )
Test hypothesis
Null hypothesis H₀ p₁ = μ
Alternative Hypothesis Hₐ p₁ ≠ μ
The Alternative hypothesis indicates that the test is a two-tail test
z(s) = ( p₁ - μ )/ √ p₁*q₁ / n
z(s) = ( 0,5547 - 0,40 )/ √ 0,5547*0,4453 / 146
z(s) = 0,1547 / 0,041
z(s) = 3,77
Comparing z(s) and z(c)
z(s) > z(c)
z(s) is in the rejection region. We reject H₀. Sample does not give evidence to support that the actual percentage of type A donations is equal to the national population
