WILL GIVE BRAINLIEST IF CORRECT!!How many different 7-digit positive integers exist? (Note that we don't allow "7-digit" integers that start with 0, such as 0123456; this is actually a 6-digit integer.)
A survey of 1000 young adults nationwide found that among adults aged 18-29, 35% of women and 30% of men had tattoos. Suppose that these percentages are based on random samples of 500 women and 500 men. Using a 2.5% level of significance, can you conclude that among adults aged 18-29, the proportion of all women who have tattoos exceeds the proportion of all men who have tattoos?

Explanation
Supplementary angles are angles that sum up to give 180 degrees.
And for all rectangles, whether a square one or non-square one, all of the angles of the rectangle are each 90 degrees.
So, it is clear that any two same side angles will be 90° + 90° = 180°
Meaning that same side angles of a non-square rectangle are supplemental.

Which system of equations has infinitely many solutions?
4 x + 2 y = 5 // -4x - 2y = 1
-10x + y = 4 // 10x - y = -4.
-8x + y = 2 // 8x-y = 0.
-x + 2 y = 6 // 7x-2y = 12.
It's important to know that a linear system of equations has infinitely many solutions when both equations represents the same line, that means one line is on top of the other one, that's why the shared infinite points.
In this case, notice that if we compare the second system, you would find that both equations are the same,
If we multiply the first equation by -1
Which means the system has infinitely many solutions, because both equations represent the same line, so the shared all possibles points.
Therefore, the right answer is the second choice.

Step-by-step explanation:
Pythogorean Theorem:
a squared + b squared = c squared
9 squared or 81 + ? squared = 15 squared or 225
Inverse Pythagorean Theorem:
c squared - a squared = b squared
225 - 81 = 144
sqrt (144) = 12
12 = b

Answer:
$300
Step-by-step explanation:
The couch is sold in two ways; outright payment or installment payment.
Outright payment would cost = $820
Installment payment = down payment + monthly charges
Down payment = $400
Monthly charges for a period of one year (12 months) = 12 × $60
= $720
Installment payment would cost = $400 + $720
= $1120
Amount saved by paying total amount at the time of purchase = $1120 - $820
= $300
Thus, the outright buying the couch would save $300.
shirts: 5 10 15
profit: $7.50 $15.00 22.50
Answers
Answer:
$1.50
Step-by-step explanation:
To find the unit rate, we can divide the number of shirts to the profit that was made to find the unit cost per shirt.
7.50 / 5 = $1.50
15 / 10 = $1.50
22.50 / 15 = $1.50
Best of Luck!
Answer: 1.5
Step-by-step explanation:
7.50/5 = 1.5
15/10 = 1.5
22.50/15 = 1.5
