The class 35 - 40 has maximum frequency. So, it is the modal class.
From the given data,
[tex]\sf \:\:\:\:\:\:\:\:\:\:x_{k}=35[/tex][tex]\sf \:\:\:\:\:\:\:\:\:\:f_{k}=50[/tex][tex]\sf \:\:\:\:\:\:\:\:\:\:f_{k-1}=34[/tex][tex]\sf \:\:\:\:\:\:\:\:\:\:f_{k+1}=42[/tex][tex]\sf \:\:\:\:\:\:\:\:\:\:h=5[/tex][tex] {\bf \:\: {By\:using\:the\: formula}} \\ \\ [/tex]

Most precisely, mode is that value of the variable at which the concentration of the data is maximum.MODAL CLASS
In a frequency distribution the class having maximum frequency is called the modal class.[tex]{\bf{\underline{Formula\:for\: calculating\:mode:}}} \\ [/tex]
[tex]{\underline{\boxed{\sf {Mode,\:M_{o} =\sf\red{x_k + {\bigg(h \times \: \dfrac{ ( f_k - f_{k-1})}{ (2f_k - f_{k - 1} - f_{k +1})}\bigg)}}}}}} \\ \\ [/tex]

Answer:
4²+b² = 5²
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem to find the length of the missing side.
The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. Algebraically, this is represented as
a²+b² = c²
We have the measure of one leg, 4 in. We also have the measure of the hypotenuse, 5 in. This gives us
4²+b² = 5²

which makes it zero
Given pair of expression :
[tex] \longrightarrow \sf {(4x -7) \: and \: (7-4x) } [/tex]
Solution :
Firstly put the sign of addition (+) at the place of and.
[tex] \longrightarrow \sf {(4x -7) + (7-4x) } [/tex]
Now, remove the brackets.
[tex] \longrightarrow \sf {4x -7 + 7-4x } [/tex]

What is the standard error of the mean?The standard error of the mean, or simply standard error, indicates how different the population means is likely to be from a sample mean. It tells you how much the sample means would vary if you were to repeat a study using new samples from within a single population.
Therefore, The value of the standard error of the mean is 1.256.

Michael purchased a chocolate swirl yogurt in a waffle cone. The yogurt cost $1.25 and the waffle cone was 50¢. He gave the clerk 8 quarters. How much did she give back to Michael?
Answers
Answer:
Michael should get $0.25 from the clerk.
Step-by-step explanation:
Add $1.25+$0.50 together which equals $1.75 and multiply $0.25x8 which equals $2.00 and subtract $1.75 from $2.00 and that equals $0.25.
Answer:
.25 = 1 quarter
Step-by-step explanation:
8 x .25 = $2.00
1.25 + .50 = $1.75
2.00 - 1.75 = .25

if a half a gallon of milk costs $1.24 then whats the cost per pint?
Answers
Answer:
Step-by-step explanation:
It costs . 31 cents for 1 pint of milk.
Answer:
1 pint would be ($1.25/4 pints) = $0.31
Step-by-step explanation:
There are eight pints in a US gallon, and thus four in half a gallon.
That comes to four pints of milk.
That's $1.24/(half gallon), or $2.48/gallon.
Since half a gallon (4 pints) is $1.25, 1 pint would be ($1.25/4 pints) = $0.31

Hannah paid $8.63 at the grocery store for beans and potatoes. She bought 4 pounds of beans at $0.62 per pound and 5 pounds of potatoes.
How much did Hannah pay per pound for the potatoes?
$3.67
$1.32
$6.15
$1.23
Answers
Answer:
$1.23
Step-by-step explanation:
First start off by multiplying $0.62 by 4 to find out the total she paid for all four pounds of beans. This would give you $2.48 spent on beans. Subtract $2.48 from the total amount spent ($8.63). You now have $6.15 left on what she could have spent on 5 pounds of potatoes. Do $6.15 divided by 5 to get an answer of $1.23. Hannah paid $1.23 per pound for the potatoes.

Answer:x=square root(239)
Step-by-step explanation:
The way to solve this is via the Pythagorean theorem(a^2 + b^2 = c^2)
a= a leg
b= another leg

16^2 = square root(17)^2 + x^2
256 = 17+ x^2
239 = x^2
x=square root(239)

The two angles with y in them need to add up to 180 degrees
10y + 3y + 11 = 180
Simplify:
13Y + 11 = 180
Subtract 11 from both sides
13y = 169
Divide both sides by 13
Y = 13
Now solve for those two angles:
10y = 10(13) = 130
3y + 11 = 3(13) + 11 = 50
The other two angles are the same as these.
The larger angles = 130
The smaller angles = 50
