Answer:
26.11% probability that Duck #2’s egg weighs more than Duck #1’s egg
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
If an egg is randomly chosen from each duck, what is the probability that Duck #2’s egg weighs more than Duck #1’s egg?
Duck #2 egg will weigh more if the subtraction of duck's 2 egg by duck's 1 egg is larger than 0.
When we subtract normal distributions, the mean is the subtraction of the means. So
[tex]\mu = 65 - 70 = -5[/tex]
The standard deviation is the square root of the sum of the variances. So
[tex]\sigma = \sqrt{6^2+5^2} = \sqrt{61} = 7.81[/tex]
Now, we have to find 1 subtracted by the pvalue of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - (-5)}{7.81}[/tex]
[tex]Z = 0.64[/tex]
[tex]Z = 0.64[/tex] has a pvalue of 0.7389
1 - 0.7389 = 0.2611
26.11% probability that Duck #2’s egg weighs more than Duck #1’s egg
Determine if the statement is true or false. Any linear system with more variables than equations cannot have a unique solution.
Answer:
True
Step-by-step explanation:
Suppose a system contains a large number of variables than equations, then there is a need to make assumptions of some values for the extra variables in order to solve the system. So, the assigning of these values can be done in several ways. Thus, the system cannot contain a unique solution.
Also, for a system of the linear equation:
[tex]AX = B[/tex] can have a unique solution if:
Augmented matrix(rank) = coefficient matrix(rank) = no. of variables.
Provided that there exist fewer equations and more variables,
Then;
coefficient matrix(rank) < no. of variables
Thus, the system cannot contain a unique solution.

find the value of the ratio a:5.7=8:12
Answer:
a = 3.8
Step-by-step explanation:
a : 5.7 = 8 : 12
It can be also written as -
[tex] \frac{a}{5.7} = \frac{8}{12} [/tex]
[tex] = > \frac{a}{5.7} = \frac{2}{3} [/tex]
Multiplying 5.7 on both the sides ,
[tex] = > \frac{a}{5.7} \times 5.7 = \frac{2}{3} \times 5.7 [/tex]
[tex] = > a = \frac{2}{3} \times 5.7 = 3.8[/tex]
A 16 ft tall adult giraffe standing next to a
baby giraffe casts a 8 ft shadow. If the
baby giraffe is 6 ft tall, then how long is
its shadow?
Answer:
The shadow is 3 ft tall
Step-by-step explanation:
The older giraffe is 16 ft tall and 8 is half of 16 and 8ft is the length of the shadow so that means that half of the small girafe would be 3ft because half of 6 is 3.

For the class picnic, 25 liters of punch were purchased. 6 liters were left over. How many gallons of punch were used at the picnic? (1 liter is approximately 0.26 gallons)
Answer:
Gallons of punch used = 4.94 gallons
Step-by-step explanation:
Given that:
Liters of punch purchased = 25 liters
Liters of punch left over = 6 liters
Liters of punch used = 25 - 6 = 19 liters
According to the given statement;
1 liter = 0.26 gallons
19 liters = 0.26*19 gallons
19 liters = 4.94 gallons
Hence,
Gallons of punch used = 4.94 gallons

Y-intercept for y=2(x-3)^2+4
Answer:
The y-intercept for this equation is 22.
Step-by-step explanation:
You can solve this quite easily by assigning a zero value to x and solving for y. That is where the curve will intersect the x-axis:
y = 2(x - 3)² + 4
y = 2(x² - 6x + 9) + 4
y = 2x² - 12x + 18 + 4
y = 2x² - 12x + 22
EDIT
Note that the expression above is in standard form, though it can also be factored if needed:
y = 2(x² - 6x + 11)
Now we can solve for an x value of zero:
y = 2(0)² - 12(0) + 22
y = 22
So the y-intercept is 22.

8. A haircut is $120, how much is a 15% tip? *
Answer:
18
Step-by-step explanation: 120 times 0.15
Answer:
$18
Step-by-step explanation:
To work out 15% using a calculator:
0.15 multiplied by 120 which is 18
To work out 15% without a calculator:
10% of 120 is 12. (Just remove the last number whenever you want to get 10% or add it on as a decimal if it's greater than 0. e.g. 10% of 40 is 4 but 10% of 48 is 4.8)
To add the 5% divide 12 by 2 which is 6.
Add the 10% to the 5% to get the 15%.
12+6=18
2) You traveled 210 miles in 3.5 hours.
How many miles will you travel per hour?
Answer:
= 56.7 miles per hour
Step-by-step explanation:
Step-by-step explanation:
To find the average speed for the entire journey, we need to find the entire distance and the total time
Entire distance = 210 miles + 130 miles = 340 miles
Total time = 3.5 hours and 2.5 hours = 6 hours
Average speed = distance/ time = 340 miles/ 6 hours
= 56.66666666666 miles per hour
Rounding to the nearest tenth
= 56.7 miles per hour
Answer:
60 miles
Step-by-step explanation:
Step 1:210=3.5
x =1
Step 2: cross multiply3.5×x= 210×1
3.5x=210
Step 3: divide both sides by the coefficient of x which is 3.53.5x/3.5=210/3.5
x=60
Answer= 60 miles

The equivalent value of the fraction is A = 1/3
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be p
Let the second fraction be q
Now , A = p - q
when the value of p = 17/15
And , when the value of q = 4/5
On simplifying the equation , we get
A = 17/15 - 4/5
So , the left hand side of the equation is equated to the right hand side by the value of ( 17/15 - 4/5 )
A = ( 17/15 - 4/5 )
Taking the LCM of the denominators of the fraction , we get
A = ( 17 - 12 ) / 15
On simplifying , we get
A = 5/15
A = 1/3
Therefore , the value of A = 1/3
Hence , the fraction is A = 1/3

You need to find the WPM (words per minute) of each person.
Andre - 208 divided by 4 = 52
Noah - 342 divided by 6 = 57
You now know that Andre types 52 words per minute and Noah types 57 words per minute.
Answer: Noah types faster because he types 57 words per minute while Andre types 52 words per minute.
Answer:Noah types faster.
Step-by-step explanation: For Andre ,You do 208 divide 4 which gives you 52.For Noah, you do 342 divide by 6 which gives you 57.And since Noah type more words which is 57 while Andre type 52, that means Noah types faster.

Eight oranges cost $1.00. How much will 4 dozen oranges coste
Gm
Answer:
Step-by-step explanation:
if 8 oranges cost 1 dollars
4 oranges cost 1/2=0.50 cents
one dozen=4*3= 12 oranges
0.50*3=1.50 dollars/dozen
4 dozen=4*1.50=6 dollars
Cost = $6.00
EXPLANATION:
0 = 1 orange
0 0 0 0 0 0 0 0 = 8 oranges = $1.00
1 dozen = 12 (oranges)
4 dozens = 48 (oranges)
