The required value of the x in the expression 2x = 128 is x = 64.
Given that,
An expression is given 2x = 128, to determine the simplified value of the x.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given expression is,
2x = 128
Dividing both the sides by 2
2x / 2 = 128 / 2
x = 64
Thus, the required value of the x in the expression 2x = 128 is x = 64.

Answer:
X = 30°, y = 15° and z = 150°.
Reason: Look below.
Step-by-step explanation:
Hey there!
When we look into the figure, we find that;
For x:
x+ 2x + 90° = 180° {Being linear pair}
or, 3x = 180°-90°
or, 3x = 90°
or, x= 90°/3
Therefore, X = 30°.
For y :
2y = x = 30° {Alternate angles are equal}
or, 2y = 30°
y = 30°/2
Therefore, y = 15°
For z:
2y + z = 180° { Being linear pair}
or, 30°+z = 180°
or, z = 180°-30°
or, z = 150°
Therefore, z = 150°.

The point (-4, 5) is reflected in the x axis. What are the coordinates of the transformed point?
Answer:
(4,5)
Step-by-step explanation:
Hehe Hope it helped yu.
The reflection across the x-axis is an illustration of transformation, and the coordinates of the transformed point is (-4,-5)
How to determine the coordinates of the transformed point?The point is given as:
Point = (-4,5)
The rule of reflection across the x-axis is:
(x,y) -> (x,-y)
So, we have:
(x,y) -> (-4,-5)
Hence, the coordinates of the transformed point is (-4,-5)

1. The probability of telesales representative making a sale on a customer call is 0.15.
Representatives are required to achieve a mean of at least 5 sales each day.
(C) Find the least number oftcalls each day a representative should make to achieve this
requirement
(d) Calculate the least number of calls that need to be made by a representative for the
probability of at least 1 sale to exceed 0.95
Answer:
1c
[tex]n = 33[/tex]
1d
[tex]n = 19[/tex]
Step-by-step explanation:
From the question we are told that
The probability of telesales representative making a sale on a customer call is [tex]p = 0.15[/tex]
The mean is [tex]\mu = 5[/tex]
Generally the distribution of sales call made by a telesales representative follows a binomial distribution
i.e
[tex]X \~ \ \ \ B(n , p)[/tex]
and the probability distribution function for binomial distribution is
[tex]P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}[/tex]
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the mean is mathematically represented as
[tex]\mu = n* p[/tex]
=> [tex]5= n * 0.15[/tex]
=> [tex]n = 33[/tex]
Generally the least number of calls that need to be made by a representative for the probability of at least 1 sale to exceed 0.95 is mathematically represented as
[tex]P( X \ge 1) = 1 - P( X < 1 ) > 0.95[/tex]
=> [tex]P( X \ge 1) = 1 - P( X =0 ) > 0.95[/tex]
=> [tex]P( X \ge 1) = 1 - [ ^{n}C_0 * (0.15 )^0 * (1- 0.15)^{n-0}] > 0.95[/tex]
=> [tex] 1 - [1 * 1* (0.85)^{n}] > 0.95[/tex]
=> [tex] [(0.85)^{n}] > 0.05[/tex]
taking natural log of both sides
[tex]n = \frac{ln(0.05)}{ln(0.85)}[/tex]
=> [tex]n = 19[/tex]
Jack wants to buy a pair of trousers for $60. When he went to the store he found that the price was marked down by 20%. How much do they cost now?
Answer: They would cost 48 dollars
Step-by-step explanation:
Answer:
$48
Step-by-step explanation:
You know that it costs $60 and it is marked DOWN by 20%. Therefore, you want to find 20% of 60 which is 12. Then, you subtract $12 from the original amount to get the cost now.

Mr Noris wrote a doubles fact. It has a sum greater than 6. The number that he added are each less than 6. What fact might he have written?
9514 1404 393
Answer:
4 + 4 = 8
5 + 5 = 10
Step-by-step explanation:
If we assume Mr Noris restricted himself to integer facts, we require both ...
2n > 6
n < 6
Dividing the first inequality by 2 gives ...
n > 3
Writing the two inequalities as a compound inequality, we have ...
3 < n < 6
There are two integers that satisfy this requirement:
n = 4 or n = 5
So, the doubles fact could have been either of ...
4 + 4 = 8
5 + 5 = 10

Which statement correctly describes the expression (-60)(-5)? A. Both factors are negative, so the product will be positive. B. Both factors are negative, so the product will be negative. O C. One factor is positive and one factor is negative, so the product will be negative. D. One factor is positive and one factor is negative, so the product will be positive. SUOMI
Answer:
a
Step-by-step explanation:
Answer:
A. Both factors are negative, so the product will be positive
Step-by-step explanation:
Remember negative times negative will always be positive
And use the process of elimination:
You know that negative times negative is not negative so that eliminates B.
And there are two negatives in the equation not one positive and one negative so it is not choice C.
The same concept applies is for choice D.

Equation of given relationship model is y = 3b.
What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
Given,
∵ each blanket requires 3 skeins of yarn

Mountain climber Joe climbed to a mountain peak that was1200 feet above its base and 1500 feet east of its base. Mountain climber Bob climbed to a mountain peak that was 900 feet above its base and 1000 feet east of its base.
Who climbed a steeper mountain? Explain.
Answer:
Mountain climber Joe climbed the steepest mountain
Step-by-step explanation:
In order to figure out who climbed the mountain you have to solve using the puthagreom theorem a squared + b squared = c squared
In this case you have multiply 12000 by 2 to replace a squared, you multiply 1500 by 2 to replace b squared and you leave c squared
Once you have that add the two numbers together, 2400+3000, this equals 5400
now you have 5400 = c squared, to solve you have to find the square root of 5400 giving you the rounded number of 73.48=c
After you have completed do the exact same thing with Mountain climber Bob. This gives you the rounded number of 61.64.
therefore, mountain climber Joe has climbed the steepest hill
i think bob climbed the steeper mountain
