Answer:
False
Step-by-step explanation:
A rhombus is a quadrilateral with
1. all side length equal
2. opposite side parallel
3. opposite angles are congruent.
______________________________________
If there are two rhombus with same side length ,
conditions so that they must be always congruent.
1. Side length must be equal
2. corresponding angles to equal sides must also be equal.
It is possible that the sides of two rhombus will be same
but their angles can differ and hence the two rhombus may or may not be congruent.
Thus,
Two rhombuses with the same side lengths are always congruent

-2=v solution
solve x (give answer as fractions or integers). 2^x =1/2
Answer:
x = -1
Step-by-step explanation:
When an exponent is negative, you have to move it to the denominator (or to the numerator if it's already on the denominator). Since the answer is [tex]\frac{1}{2}[/tex], you know that the 2 has been raised to the power of 1 (any number to the power of 1 is the same number), so you just make it negative. Hope that helps!
What is another way to write the absolute value inequality |p|≤12
Answer:
p <= 12 and p >= -12
Step-by-step explanation:
The absolute value of p means that p is less than 12. Then, -p must be greater than -12

In a one-minute time period, Joseph read 2 times as many words as
John. Together they read 669 words. How many words did each boy
read?
Answer:
John: 223 words
Joseph: 446 words
Step-by-step explanation:
Set up the equation, 2x + x = 669 to find out how many words each boy read.Combine like terms. 3x = 669.Divide by 3 on both sides. x = 223. This is the amount of words John read. To find out how many words Joseph read, multiply 223 and 2, which is 446.Find the equation of the line that is perpendicular to y = – 1 3 x + 2 and passes though the point (–5, 2).
A) y = 3x + 13
B) y = 3x + 17
C) y = –3x + 13
D) y = –3x + 17
Answer:
The required equation is y = 3x + 17. Correct: B)
Explanation:
Equation of a line
A line can be represented by an equation of the form
y=mx+b
Where x is the independent variable, m is the slope of the line, m is the y-intercept and y is the dependent variable.
We are given the equation of a line as (corrected)
y=-1/3x+2
Note the slope of this line is m1=-1/3
We are asked to find the equation of another line that is perpendicular to the one above. Two lines are perpendicular if their slopes comply with the following condition:
[tex]m_1*m_2=-1[/tex]
Since we have m1, find m2:
[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]
[tex]\displaystyle m_2=-\frac{1}{-\frac{1}{3}}=3[/tex]
This means the slope of the required line is 3. We only have to test the options to find which one of us contains the point (-5,2):
A) The slope of this line is 3, so we test the point (-5,2)
2=3(-5)+13=-15+13=-2
Since 2 is different from -2, this option is not correct
B) The slope of this line is 3, so we test the point (-5,2)
2=3(-5)+17=-15+17=2
Since equality stands, this is the correct option
C) The slope of this line is -3, it cannot be the required line. This option is not correct
D) The slope of this line is -3, it cannot be the required line. This option is not correct

9. Ashley's bank account had a balance of -$448.37. She deposited 3
checks of $105.30. What is Ashley's new bank account balance after the
deposits?
Answer:
-$132.47
Step-by-step explanation:
you multiply 3 by 105.3 since she has 3 deposits of the same amount
3*105.3=315.9
Ashley has -$448.37 so you add $315.9 which is the total amount she deposited
-448.37+315.9=-132.47
Ashley has -$132.47 after the deposits

Pls
Answer:
Hello! :) I hope I’m correct!!
Step-by-step explanation:
I think the answer should be: X = 12
The steps in order to solve the problem is:
1. You have to subtract 1 from both sides.
2. Simplify.
3. Now you have to add 7|x-12| to both sides.
3. Than you have to simplify again.
4. Next divide both of the sides by 11.
5. And than you simplify again.
6. Use the rule “ If |u| = 0 than u = 0
( x - 12 = 0)
Therefore the answer would be:
X = 12
Hope this helps!!

15. True or False: Is x = 4 a solution to X + 51 = -9
True
False
Answer:
False
Step-by-step explanation:
if x=4 the answer would not be -9
x+51 would add up to 55
so it would be : 4+51=55
now if we wanted the answer to be -9 , x would have to be different
-60+51=-9
but in this case x is no -60, it's 4, so no this statement is false.
Spectrum provides cable television and Internet service to over million customers. Suppose that the management of Spectrum subjectively assesses a probability distribution for the number of new subscribers next year in the state of New York as follows. 100,000 0.08 200,000 0.20 300,000 0.24 400,000 0.29 500,000 0.11 600,000 0.08 a. Is this probability distribution valid? Yes b. What is the probability Spectrum will obtain more than new subscribers? (to 2 decimals) c. What is the probability Spectrum will obtain fewer than new subscribers? (to 2 decimals)
Complete question :
a. Is this probability distribution valid? Yes b. What is the probability Spectrum will obtain more than 400,000 new subscribers? (to 2 decimals) c. What is the probability Spectrum will obtain fewer than 200,000 new subscribers? (to 2 decimals)
Answer:
Yes ; 0.19 ; 0.08
Step-by-step explanation:
Given the data:
__X_______p(X)
100,000___ 0.08
200,000__ 0.20
300,000__ 0.24
400,000__ 0.29
500,000___ 0.11
600,000___0.08
a. Is this probability distribution valid?
To determine validity of the distribution :
ΣP(X) must be equal to 1
(0.08 + 0.20 + 0.24 + 0.29 + 0.11 + 0.08) = 1
Hence, the distribution is valid.
What is the probability Spectrum will obtain more than 400,000 new subscribers
Probability of obtaining more than 400,000 new subscribers :
P > 400,000 = P(500,000) + P(600,000)
= 0.11 + 0.08 = 0.19
C.) What is the probability Spectrum will obtain fewer than 200,000 new subscribers?
P < 200,000 = P(100,000)
= 0.08
