Answer:
x = 95
Step-by-step explanation:
Given that,
Jax scores on the last 5 tests are 78,92,86,94,95.
We need to find the score he need to have an average of 90.
The formula for average of few number is given by :
Average = sum of observations/total no of observation
Let he score x in test 6. So,
[tex]90=\dfrac{78+92+86+94+95+x}{6}\\\\90=\dfrac{445+x}{6}\\\\540=445+x\\\\x=95[/tex]
So, he must score 95 in the next test so that its average is 90.

Question Of The Day:
When John was six years old, he hammered a
nail into his favorite tree to mark his height. Ten
years later at age sixteen, John returned to
see how much higher the nail was. If the tree
grew by five centimeters each year, how
much higher would the nail be?
If the tree grew by five centimeters each year, then the tree will grow 50 cm in 10 years.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the given information in the question,
Age when John hammered a nail in the tree = 6 years
John returned to the age of sixteen, then the number of years in between that,
16 - 6 = 10 years.
Rate of increase in height of tree per year = 5 cm
Then, after 10 years, the height of the nail of the tree will be,
10 × 5 = 50 cm.

Evaluate x−y if x=−5 1/4 and y=−6.8 . Write your answer in simplest form.
The answer i got is -1.55, im not sure though
The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
As per the given expression, x - y
x = - 5 1/4 = (-5 x 4 + 1)/4 = -19/4 = -4.75
y = -6.8
Substitute x and y into the above expression,
-4.75 - (-6.8) = 2.05
Hence "The value of the given algebric expression is x - y when x=−5 1/4 and y=−6.8 will be 2.05".

How would you write an equation with a slope of 2/3 and a y-intercept of -3
A.y=2/3-3 B.y=3/2x+3 C.y=2/3x-3
Answer: The answer is C) y= 2/3x-3
Step-by-step explanation:
i figure it out
Answer:
C
Step-by-step explanation:
so obviously your slop is 2/3. so it starts with y=2/3. so B is out of the question. since the slope is x in the equation, you still have to add the x in the equation; y=2/3x

3 is not in the range.
What is the range?A function's range is the whole set of potential values that it can have. When we insert an x value into the function, the range is the collection of values that results. Range refers to the y values.
Given a figure in which the function is not differentiable since the graph is broken at (-2, 3) and (2, 4). Since at Y = 3 there is no point in the graph. therefore Y = 3 is not in the range of the function.

An artist mixes 25 ounce of blue paint with 115 ounce of green paint. Using the same ratio, how many ounces of green paint should she mix with 3 ounces of blue paint?
Answer:
Ounces of green paint needed = 13.8
Step-by-step explanation:
Blue paint : green paint = 25 : 115
how many ounces of green paint should she mix with 3 ounces of blue paint?
Let
Ounces of green paint needed = x
Blue paint : green paint = 3 : x
Equate both ratios
25 : 115 = 3 : x
25/115 = 3/x
25 * x = 115 * 3
25x = 345
x = 345/25
x = 13.8 ounces
Ounces of green paint needed = 13.8
