Answer:
B' (-2, 3)
Step-by-step explanation:
A(5, 1) to A'(6, -2)
A(6-5, -2-1)
A translation is 1, -3
consider the same translation of B'
therefore, the coordinates of B' is (-2, 3)
Answer:
B. -2, 3

Answer:20
Step-by-step explanation:
Given Wind speed is 2 mile/hr
Let jamie speed be x km/hr
Also she covered 44 miles with wind in time t
Against the wind
divide the two equations
11x-22=9x+18
x=20 miles/hr

Q2 Answer: Experimental = 60%, difference = 10%
Step-by-step explanation:
The prime numbers between 1 and 8 are: 2, 3, 5, and 7.
Theoretical:
Experimental:
Experimental - Theoretical
= 60% - 50%
= 10%
Problem 1
To find the sample mean, we simply add up all the 40 items and then divide by 40
I will add up the values row by row, and then add up the subtotals to get the grand total
row1: 39+31+38+40+29 = 177
row2: 32+33+39+35+32 = 171
row3: 32+27+30+31+27 = 147
row4: 30+29+34+36+25 = 154
row5: 30+32+38+35+40 = 175
row6: 29+32+31+26+26 = 144
row7: 32+26+30+40+32 = 160
row8: 39+37+25+29+34 = 164
Add up the subtotals: 177+171+147+154+175+144+160+164 = 1292
Divide this over 40: 1292/40 = 32.2
So the sample mean is therefore 32.2
-----------------------
To find the proportion of defective items, we count the number of times a value less than 26 shows up. That happens exactly two times. The first in row 4 (at the end of this row) is where a 25 shows up. Another copy of 25 shows up in row 8 (bottom row). There are no other values that are less than 26.
Divide this count (2) over the total sample size (40) and we get 2/40 = 1/20 = 0.05
-----------------------
In summary, 32.2 will go in the first box while 0.05 will go in the second box.
========================================
Problem 2
There are 4 values we want (2,3,5,7) out of 8 total (1,2,3,4,5,6,7,8) so 4/8 = 0.50 = 50% is the theoretical probability
This is the list of values given to us (I broke it up to help make the numbers more readable)
3, 4, 5, 2, 7
1, 3, 7, 2, 6
2, 1, 7, 3, 6
1, 8, 3, 5, 6
Of that list, the primes {3, 5, 2, 7, 3, 7, 2, 2, 7, 3, 3, 5} show up. There are 12 primes in this list out of 20. So the experimental probability is 12/20 = 3/5 = 0.60 = 60%
Therefore, the answer that goes in the "experimental probability" box is 60. The answer that goes in the second box is not 50%. I think your teacher is aiming for "10" to go in the second box because 60% is 10 percentage points higher than 50% (which was the theoretical probability found earlier)
-----------------------
In summary, 60 will go in the first box while 10 will go in the second box.
Answer:
6 cup of milk
Step-by-step explanation:
From question
for 11 cookies → of a cup of milk required
Now,
for 99 cookies
we multiply both sides by 9.
11 × 9 = × 9
for 99 cookies = 6 cup of milk
Which of the following statement about (c + 2)(15c – 14) is true?
A. The expression is equivalent, and it is completely factored.
B. The expression is equivalent, but it is not completely factored.
C. The expression is not equivalent, but it is completely factored.
D.The expression is not equivalent, and it is not completely factored.
Answer : C. The expression is not equivalent, but it is completely factored.
can be factored
15 * -28 = -420
21 and -20 are the factors whose sum is +1 and product is -420
This is not equivalent to (c + 2)(15c - 14)
But (c + 2)(15c – 14) is completely factored
So , The expression is not equivalent, but it is completely factored.
Answer:
-9
Step-by-step explanation:
180=85+44+60+(x)-9
Answer:
A. -9
Step-by-step explanation:
A triangle equals 180 degrees so:
60 + 85 + x + 44 = 180
add like terms
x + 189 = 180
subtract 189 from both sides
x = -9
