1 out 4
Step-by-step explanation:
A CEO wondered if her company received either more or less complaints from its workers on Monday than any other day. She figured that if it were truly random, 20% of the complaints should have been filed on Monday. She randomly selected 50 complaints and checked the day that they were submitted. In those complaints 13 were submitted on a Monday. The CEO conducts a one-proportion hypothesis test at the 5% significance level, to test whether the true proportion of complaints submitted on a Monday is different from 20%. (a) Which answer choice shows the correct null and alternative hypotheses for this test?

Rohan draws a circle of radius 10 cm with the help of compass and scale. He also draws two chords, AB and CD in such a way that AB and CD are 6 cm and 8 cm from the centre O. Now, he has some doubts that are given below. Help him out by answering these questions:
a)what will be the chord of ab?
b)what wil be the chord of cd?
Answer:
a) 16 cmb) 12 cmStep-by-step explanation:
Connect the center with A and C:
OA = 10 cm or OC = 10 cmUse Pythagorean to find half of AB:
[tex]AB/2=\sqrt{10^2-6^2} =\sqrt{64} =8[/tex][tex]AB = 16[/tex]Similarly, find the length of CD:
[tex]CD/2=\sqrt{10^2-8^2} =\sqrt{36} =6[/tex][tex]CD=12[/tex]
Length of AB = 16 cm
h² = p² + b²
10² = 6² + b²
100 = 36 + b²
[tex]b = \sqrt{64} [/tex]
[tex]= 8 cm[/tex]
[tex]AB = 8 + 8[/tex]

The volume of a right circular cylinder is 1100 cm3 and the radius of its base is 5 cm. Calculate its curved surface area.
(A) 410 cm2 (B) 125 cm2 (C) 440 cm2
Answer:
c
Step-by-step explanation:
t r r rt t t 4 4. 54. 54. 54 4. rr. rt t. t
Answer: A
Step-by-step explanation: πr2 h = 1100 cm³
Here r = 5
(22/7) ⋅ (5)2 ⋅ h = 1100
h = 2/7
Curved surface area of cylinder = 2 πr h
= 2 ⋅ (22/7) ⋅ 5 ⋅ (2/7)
= 440 cm²
So, the curved surface area of cylinder is 440 cm²
5. What is the distance from V to W? V=8 cm W 15 cm m<VW= 90
Answer:
17 cm
Step-by-step explanation:
If the angle between V and W is 90°, then this implies that V and W are legs of a right triangle (and the distance between them is the hypotenuse).
Use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse of a right triangle.
Let D = distance between V and W:
⇒ V² + W² = D²
⇒ 8² + 15² = D²
⇒ 289 = D²
⇒ D = √289
⇒ D = 17
Therefore, the distance from V to W is 17 cm
[tex]\huge \boxed{\sf 17\ cm}[/tex]
Pythagoras discovered that the square of the hypotenuse of a right-angled triangle, where one of the angles is 90 degrees, equals the sum of the squares of the other two sides.
[tex]\sf a^2 + b^2=c^2\\\\8^2 + 15^2=c^2\\\\ \sqrt{8^2 + 15^2} =c\\\\17=c[/tex]

solve the inequality 5(2h+8)+60
Answer:
h=10
Step-by-step explanation:
5(2h+8)+60
5 × 2h = 10h
5× 8 = 40
10h + 40 + 60
40 + 60 = 100
10h = 100
100/10h
h=10
3/5 x 1/3 Show your work as well
Answer:
1/5 to simplest terms
Step-by-step explanation:
[tex]\frac{3}{5}[/tex]×[tex]\frac{1}{3}[/tex]
To do this you simply multiply the numerators and you multiply the denominators:
3×1=3 (numerator)
5×3=15 (denominator)
[tex]\frac{3}{15}[/tex] = 1/5
To do the last step of making 3/15 to 1/5 I divided top and bottom by 3, that is how you simplify a fraction

Perimeter of triangle NOP = NO + OP + NP
Find NO:
NO = |3 - (-3)| = 6 units
Find NP:
NP = |-4 - 5| = 9 units
Using the distance formula, find OP:
OP = 10.8 units
Therefore, Perimeter of the triangle = 10.8 + 9 + 6 = 25.8 units.

solve: y = 3x - 4
y = x + 2
Answer:
y = 5
Step-by-step explanation:
Isolate x to plug in to other equation
y = x + 2
-y-x -y-x
(- x = -y + 2) / -1
x = y - 2
Plug into other equation
y = 3(y-2) - 4
Distribute
y = 3y-6-4
y = 3y-10
-3y -3y
(-2y = -10)/-2
y = 5
Milo is making 1 1/2 batches of muffins for a bake sell. If each batch of muffins calls for 1 3/4,how many cups of flour will he need ?
Answer:
2 5/8
Step-by-step explanation:
Because she has one whole batch of cookies that will require 1 3/4 of flour. Since the remainder is a 1/2 batch, you would have to half the 1 3/4. Halfing 1 3/4 is 7/8. You add 1 3/4 + 7/8 and you get 2 5/8.
