Answer:
kindergarten = 88
first = 73
second = 68
third = 88
Step-by-step explanation:
365=k+f+s+t
2s=t
s+5=f
f+15=k
USE SUBSTITUTION
365=((s+5)+15) + (s+5) + s + (2s)
365=5s+25
-25 -25
340=5s

t=2(68)=136
f=(68)+5=73
k=(73)+15=88

You measure 22 watermelons' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 6.9 ounces. Based on this, construct a 95% confidence interval for the true population mean watermelon weight. Give your answers as decimals, to two places
Answer:
Step-by-step explanation:
Confidence interval formula is expressed as;
CI = xbar ±(z*s/√n)
xbar is the mean = 36
z is the z score at 95% CI = 1.96
s is the standard deviation = 6.9
n is the sample size = 22
Substitute
CI = 36 ±(1.96*6.9/√22)
CI = 36 ±(1.96*6.9/4.6904)
CI = 36 ±(1.96*1.4711)
CI = 36 ± 2.8833
CI = (36 - 2.8833, 36 + 2.8833)
CI = (33.1167, 38.8833)
Hence the 95% CI for the true population mean is 33.12<x<38.88

You need to make at least 360 wraps for a party. You can make 9 wraps per minute.
How long will it take you to make the number of wraps you need?
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the inequality.
Answer:
40 minutes
Step-by-step explanation:
What the person above/below me is saying, is you have to divide 360 and 9, to find x! X=40, 360/9=40! That's what they mean. I hope this helped you understand their answer!
It will take 40 minutes for me to make the 360 wraps that I need.
9x ≥ 360 ⇒ x ≥ 40
Step-by-step explanation:
I have to make at least 360 wraps for a party.
I can make 9 wraps per minute.
So, it will take minutes for me to make the 360 wraps that I need.
If I work for x minutes to make wraps, then I will be able to make 9x wraps.
So, the inequality that models the given condition is
9x ≥ 360
⇒ x ≥ 40 {Dividing both sides by 9}
Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

We are given the equation:
√(4x - 2) + 3 = 5
Subtracting by 3 on both sides
√(4x - 2) = 2
Squaring both sides
4x - 2 = 4
Adding 2 on both sides
4x = 6
x = 3/2
Step-by-step explanation:
Hey there!
Given;
[tex] \sqrt{4x - 2} + 3 = 5[/tex]
Shift "3" on right side.
[tex] \sqrt{4x - 2} = 5 - 3[/tex]
[tex] \sqrt{4x - 2} = 2[/tex]
Squaring on both sides.
[tex] {( \sqrt{4x - 2} )}^{2} = {2}^{2} [/tex]
Simplify it.
[tex]4x - 2 = 4[/tex]
[tex]4x = 4 + 2[/tex]
[tex]x = \frac{6}{4} [/tex]
[tex]x = \frac{3}{2} [/tex]
Therefore, X = 3/2.

To get ready for the move you made two trips to the local hardware store. You purchased packages of lightbulbs and packages of batteries so that you would not run out. Each package of lightbulbs was the same. Each package of batteries was the same; however, the price of the lightbulbs is different from the price of the batteries.
On your first trip, you spent $109.78 and purchased 4 packages of lightbulbs and 5 packages of batteries.
On your second trip, you spent $171.72 and purchased 6 packages of lightbulbs and 8 packages of batteries.

The sum of two numbers is 59. The larger number is 7 more than the smaller number. What are the numbers?
Answer:
26 and 33
Step-by-step explanation:
7+a+a=59
7+2a=59
2a=59-7
2a=52
a=52÷2
a=26
The bigger number is 7 more bigger therefore
26+7= 33

Step-by-step explanation:
Find the value of StartFraction partial derivative z Over partial derivative x EndFraction at the point (1,1,1) if the equation 5 xy plus z Superscript 4 Baseline x minus 3 yz equals 3 defines z as a function of the two independent variables x and y and the partial derivative exists.
Looks like the given curve is
5xy + z⁴x - 3yz = 3
Differentiate both sides with respect to x :
5y + 4z³x ∂z/∂x + z⁴ - 3y ∂z/∂x = 0
Solve for ∂z/∂x :
(4z³x - 3y) ∂z/∂x = - (5y + z⁴)
∂z/∂x = - (5y + z⁴) / (4z³x - 3y)
At the point (1, 1, 1), this derivative is
∂z/∂x (1, 1, 1) = - (5 + 1) / (4 - 3) = -6

5). Median 38°
6). Range 50° - 30° = 20°
7). 38° - 30° = 46° - 38°
50° - 38° = 12°
50° is an outlier.

What could be shown about the diagonals of parallelogram PQRS to compare the proof that diagonals of a parallelogram bisect each other?
Answer:
C. PR and SQ have the same midpoing
Step-by-step explanation:
The theorems that could be shown hat the diagonals of parallelogram PQRS bisect each other are explained below.
Let the point where the diagonals intersect be called Point T.Now, looking at the parallelogram, we can say that;
∠QPT = ∠SRT (This is because the alternate angles between 2 parallel lines are always equal)
Secondly, ∠PQT= ∠RST.This is This is because the alternate angles between 2 parallel lines are always equal.
Thirdly; ∠PTQ=∠RTSThis is because they are vertically opposite angles.
Now, from AAA congruence theorem, we can say that;△PTQ is congruent to △RTS.
Thus, we can say that;
PT = RT and QT = ST
This proves that they bisect each other.
