1.8 divide by 0.72 explain
Answer:
0.40
Step-by-step explanation:
Change the divisor 1.8 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
7.2 ÷ 18 = 0.40
and therefore:
0.72 ÷ 1.8 = 0.40
Both calculated to 2 decimal places.

Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm

Given:
Line segment labelled y is the midsegment of the triangle.
To find:
The measures of x, y and z.
Solution:
Since line segment labelled y is the midsegment of the triangle. So, it divides the included sides in two equal parts.
Line segment labelled y is bisector of both included sides.
[tex]x=21[/tex] units
[tex]z=2\times 16[/tex]
[tex]z=32[/tex] units
According to the midsegments theorem, the length of the midsegment is half of third side or non included side of the triangle.
[tex]y=\dfrac{14}{2}[/tex]
[tex]y=7[/tex] units
Therefore, [tex]x=21\text{ units},y=7\text{ units},z=32\text{ units}[/tex].

For a hypothesis test of H0: p = 0.35 against the alternative, Ha: p > 0.35, the z test statistic is found to be 2.45. What can be said about this finding?
a. The finding is significant at α = 0.05, but not at α = 0.01.
b. The finding is significant at α = 0.01, but not at α = 0.05.
c. The finding is significant at both α = 0.05 and α = 0.01.
d. The finding isn't significant at α = 0.05 and α = 0.01.
e. The finding is inconclusive because we don't know the value of p.
Answer:
c? sorry if it's wrong...
The correct statement is,
⇒ The finding is significant at both α = 0.05 and α = 0.01.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
For a hypothesis test of H₀, p = 0.35 against the alternative,
And, Hₐ: p > 0.35, the z test statistic is found to be 2.45.
Now, We get;
P(z < 2.45) = 0.9929
Hence, Significant is,
⇒ 1 - 0.9929 = 0.0071
Thus, Significant at both 0.05 and 0.01 because both are greater than 0.0071.
So, The correct statement is,
⇒ The finding is significant at both α = 0.05 and α = 0.01.

Answer:
268
Step-by-step explanation:
Answer:
The number that goes in the box is 268
Step-by-step explanation:
Equations
We are given an incomplete identity:
___ + 308 - 126 = 450
And it's required to fill the space with the number that makes the identity true.
Let's fill the space with a variable x:
x + 308 - 126 = 450
Solving for x implies doing inverse operations as shown on the left side.
We must add 126 and subtract 308:
x = 450 + 126 - 308
x = 268
The number that goes in the box is 268
Ritu and Jitu both deposited Rs 100 in a Bank. Ritu deposited for 5 years with interest rate 8% per year and Jitu deposited for 4 years with interest rate 9% per year. Who will get more interest? By how much?
Step-by-step explanation:
Step 1
For Ritu,
Principal(P) = Rs 100
Time(T) = 5 year
Rate(R) =8%pa
Intrest (I) = ???
We know,
I = P*T*R /100
= 100*8*5/100
=Rs40
now
For Jitu,
Principal(P) =Rs 100
Rate(R)=9%pa
Time (T) = 4 year
Intrest(I) =?
We have
I = P*T*R/100
=100*4*9/100
=Rs36
Step 2
We have
Intrest of Ritu have more then that of Jitu so she makes more profit
now Profit diffrence =Rs40-Rs36
=Rs4
Therefore Ritu gets 4 more profit then Jitu

Evaluate the function g(x) = -2x2 + 3x - 5 for the input values -2, 0, and 3.
9(-2) = -2(-2)2 + 3(-2) – 5
9(-2) = -2(4) - 6 - 5
g(-2) =-19
g(0) =-5
g(3) =-14
Answer:
g(-2) = -19, g(0) = -5 and g(3) = -14
Step-by-step explanation:
The given function is :
[tex]g(x) = -2x^2 + 3x - 5[/tex] ...(1)
We need to find the function when x = -2,0 and 3.
Put x = -2 in equation (1).
[tex]g(-2) = -2(-2)^2 + 3(-2) - 5\\\\=-19[/tex]
Put x = 0 in equation (1).
[tex]g(0) = -2(0)^2 + 3(0) - 5\\\\=-5[/tex]
Put x = 3 in equation (1).
[tex]g(3) = -2(3)^2 + 3(3) - 5\\\\=-14[/tex]
Hence, g(-2) = -19, g(0) = -5 and g(3) = -14
