Answer:
f
Step-by-step explanation:
Answer:
Angle MJK = 64°
Step-by-step explanation:
In ∆MJL & ∆LJK,
JL= JL ...(common side)
Angle JML = Angle JKL ....( each 90°)
MJ = JK ....( Both measures 7)
Hence, by SAS criteria, ∆ MJL = ∆ LJk
.°. by C.P.C.T , ∠MJL = ∠LJK = 32°
Also,
∠MJK = ∠MJL+∠LJK
∠MJK = 32°+32°
<h2>∠MJK = 64°</h2>
This equation works for 3x+11 over 2
(3x + 11) /2 = -2
(3x + 11) = 4
3x = -7
x = 2.3333(repeating) or 2 1/3
Answer:
a) T test
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
Step-by-step explanation:
Construction of hypothesis
H₀ : p = 75
H₁ : p ≠ 75
Here Standard deviation = 7
sample = n = 50
Average = x-bar = 78
Level of significance:
∝ = 5% = 0.05
Degree of freedom:
df = n-1
= 50 -1 = 49
Critical value :
± 1.96
a) T test
test t is used as average X mean is used
Test Statistic:
t = X₂ - X₁ / Sd /√n
= 78 - 75 / 7/√50
=3.0304
Critical region :
We take two tail T test
test statistic is in reject interval. Reject H₀
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
Solution
The dimension of the rectangular floor is 18ft long and 12 ft wide
Using the conversion table
It is given that 1yd =3 ft
This shows that
12 feet will be equivalent to
Also 18ft will be equialent to
Therefore the new dimension is 6 yard by 4 yard
The area will be
Therefore the required area is
