Answer: The standard error of the sample mean = 0.44
Step-by-step explanation:
Standard error of the sample mean = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex] , where [tex]\sigma[/tex] = population standard deviation , n= sample size.
Given : n= 45 , [tex]\sigma= 2.96[/tex] grams
The e standard error of the sample mean [tex]=\dfrac{2.96}{\sqrt{45}}[/tex]
[tex]=\dfrac{2.96}{6.7082039325}\\\\\approx\ 0.44[/tex]
Hence, the standard error of the sample mean = 0.44

Consider WXY and BCD with X= C, WX = BC, and WY = BD. Can it be concluded that WXY = BCD by SAS?
Answer:
nswer:- B. No, because the corresponding congruent angles listed are not the included angles. Given:- ΔWXY and ΔBCD with ∠X ≅∠C, WX ≅ BC, and WY ≅ BD. We can see that ∠X and ∠C are not included angles by the corresponding equal sides.
Answer:
Yes
Step-by-step explanation:
I will write it in the form of a theorem
Given:
X=C; WX=BC;WY=BD
To prove:
WXY = BCD
Proof:
X=C (This is a angle)
WX=BC
WY=BD
Since there is an angle between two equal side for both triangle WXY is congruent or '=' BCD ny SAS.
Jada solved the equation -g - 108 for x using the steps below. What was Jada's error?
Answer: Choice A) Jada should have multiplied both sides by 108.
Reasoning:
x is a placeholder for some unknown value. We are dividing x by 108 to form the fraction x/108. To isolate x, we need to undo this operation. So we need to multiply both sides by 108. Doing so leads to the solution x = -48.

Answer:
x = 65°y = 32.5°Step-by-step explanation:
ΔBCD is isosceles, so ∠CDB = ∠CBD = x. The sum of angles in the triangle is 180°, so you have ...
x + x + 50° = 180°
2x = 130° . . . . . . . . . subtract 50°, collect terms
x = 65° . . . . . . . divide by 2
__
Triangle ABC is also isosceles, so ∠BAC = ∠BCA = y. Angle ABC is the supplement of angle x. The sum of angles in ΔABC is 180°:
y + y + (180° -x) = 180°
2y - 65° = 0 . . . . . . . . . . subtract 180°, substitute the value of x
y -32.5° = 0 . . . . . . . divide by 2
y = 32.5° . . . . . . . . . . add 32.5°

on a road trip to wisconsin, Lisa and Gavin drove for 3 hours. they traveled 180 miles in that amount of time. What was their rate or speed (miles PER hour)?
Answer:
60
Step-by-step explanation:
180 divided by 3 is 60 so its 60mph
Answer:
60 miles per hour
Step-by-step explanation:
To get the mph, you have to divide the miles traveled by the time, so 180 divided 3 = 60 mph.

the base Dimensions of a rectangular box are 1.5×10 to the second power centimeters by 4.3×10 to the first power centimeters find the base area of the box right answer and say scientific notation and round coefficients to the nearest
Answer:
[tex]Area = 6.5 * 10^3cm^2[/tex] or [tex]Area = 6.5E3\ cm^2[/tex]
Step-by-step explanation:
Given
[tex]Width = 1.5 * 10^2cm[/tex]
[tex]Length = 4.3 * 10^1cm[/tex]
Required
Determine the Area
The base area is calculated as:
[tex]Area = Length * Width[/tex]
[tex]Area = 1.5 * 10^2cm * 4.3 * 10^1 cm[/tex]
Reorder the expression
[tex]Area = 1.5 * 4.3 * 10^1 cm* 10^2cm[/tex]
[tex]Area = 6.45 * 10^1 cm* 10^2cm[/tex]
Apply law of indices
[tex]Area = 6.45 * 10^{1+2}cm^2[/tex]
[tex]Area = 6.45 * 10^3cm^2[/tex]
Approximate
[tex]Area = 6.5 * 10^3cm^2[/tex]
or
[tex]Area = 6.5E3\ cm^2[/tex]

Are the triangles similar?
These triangles are not similar.
These triangles are similar by AA.
These triangles are similar by SAS.
These triangles are similar by SSS.
Answer:
These triangles are not similar I think
Hi there! Let's solve this problem step by step. :)
We have two triangles, QRP and XYP. You're given a few values.
It is given that QR = 16. QP = 6 + 18. RP = 5 + 15. Go ahead and add those.
QR = 16, QP = 24, RP = 20.
Now XYP!
XY = 12. YP = 15. XP = 18.
If you know the corresponding parts between these triangles--they should be QR to XY, QP to YP, and RP to XP. Those are 16/12, 24/15, and 20/18. Divide those.
You get 1.3333, 1.6, and 1.1111. Your turn! Are they similar?
[P.S., if you're confused about the AA/SAS/SSS similarity postulates, that just means the sides they have in common. You're not given any angle measurements, so SAS (side angle side) is out. SSS is possible, but since the ratios aren't equivalent, SSS is out. Again, AA (angle-angle) isn't possible because you're not given any angle measurements.)
That's it! :)
Good day, friend.

Given that 2 + h − 4 = 0 has no roots. Find the ranges of value of .
Answer:
here is your answer.....
Step-by-step explanation:
2 + h - 4 = 0
LHS:
2 - 4 + h
-2 + h
Therefore:
-2 + h = 0
h = 0 - 2
h = - 2
SO,
the value of h is -2

Answer:
By hypotenuse - side test (HL) the two triangles are congruent.
Step-by-step explanation:
In ∆ABC and ∆DCB
i) angleABC = angleDCB.....(each 90°)
ii) BC = BC .....( common side)
iii) AC = DB.....(given)
therefore by hypo-side test ∆ABC congruent ∆DCB
Answer:
HL
Step-by-step explanation:
∠B ≅ ∠C = 90°
AC = DB {Given and they are hypotenuse}
BC = CB {Reflexive property}
ΔABC ≅ ΔDCB {HL congruent}

solve for x
this is really difficult
Answer:
all the angles in a triangle will add to 180
65 + 57 + 2x = 180
subtract the 65 and 57 from both sides
2x = 58
x = 29
D) 29
hope this helps :)
Step-by-step explanation:
Answer: x=29
Step-by-step explanation:
In a triangle, the sum of the measures of all angles is 180 degrees.
Therefore, we can add up all the angles in this triangle, setting them equal to 180:
65+57+2x=180
Using the equation above, solve for x:
Simplify:
122+2x=180
Subtract 122 from both sides:
(122+2x)-122=180-122
Simplify:
2x=58
Divide both sides by 2:
2x/2=58/2
Simplify:
x=29

A = {3, 5, 7, 9} and B = {1, 2, 4, 6, 7, 9}
Find the intersection: A Intersects withB.
{7, 9}
{1, 2, 3, 4, 5, 6, 7, 9}
{1, 3, 5}
{2, 4}
Answer:
A∩B={7,9}
Option A is correct option.
Step-by-step explanation:
We are given:
A = {3, 5, 7, 9} and B = {1, 2, 4, 6, 7, 9}
and we need to find A intersects with B i.e. A∩B
We find A intersects with B, we will consider only those terms that are common in both A and B
So,
A∩B= {3, 5, 7, 9} ∩ {1, 2, 4, 6, 7, 9}
As 7 and 9 are only common in both A an B
A∩B={7,9}
So, we get: A∩B={7,9}
Option A is correct option.

Step-by-step explanation:
The range of the integers 20, 6, 18, -15, -12 is
a) 20
b) 35
c) -25
d) -15
Answer:
B. 35
Step-by-step explanation:
The range of a set of numbers is the difference between the highest and lowest numbers in the set.
1. Find the highest and lowest numbers from the set. Arranging them from least to greatest can make this easier.
-15, -12, 6, 18, 20
The lowest number is -15 and the highest is 20.
2. Subtract these two numbers to find the range.
20 -- 15
Two minus signs like that make a positive, so it becomes an addition problem.
20 + 15 = 35
Answer is b.
I also think the right option is B)- 35
k/2 - 5k + 3 =4 solve
Answer:
k=0
Step-by-step explanation:
/2-5K+3=4
We move all terms to the left:
/2-5K+3-(4)=0
determiningTheFunctionDomain
-5K+3-4+/2=0
We add all the numbers together, and all the variables
-5K-1+/2=0
We multiply all the terms by the denominator
-5K*2-1*2+=0
We add all the numbers together, and all the variables
-5K*2=0
Wy multiply elements
-10K=0
K=0/-10
