Answer:
n = - 4
Step-by-step explanation:
6n + 9 = -3n - 21 - 6
6n + 3n = - 21 - 6 - 9
9n = - 27 - 9
9n = -36
n = -36/9
n = - 4
The t-distribution has less extent as degrees of freedom increase since as increases less information is recognized the about or by the law of large numbers. As the degrees of freedom increases the critical t value drops that happens to the critical value of t for a particular alpha level when df increases in value.
We know that
CE=CD+DE
in the right triangle EDF
cos 38°=EF/DE-----> DE=EF/cos 38°-----> DE=17/cos 38°----> DE=21.57 units
∠FDE=90-38----> 52°
∠BDC=∠FDE------> vertical angles
so
∠BDC=52°
in the right triangle BDC
cos 52°=BD/CD-------> CD=BD/cos 52°----> CD=10/cos 52°---> CD=16.24
CE=CD+DE----> CE=16.24+21.57----> CE=37.81 units
the answer is
<span>the length of CE is </span>37.81 units

Answer:
226.08 cm³
Step-by-step explanation:
Hi!
To find the volume of a cone, you do 1/3 (3.14) × r² × h.
So all we have to do is substitute 6 in our r and h spots.
1/3 (3.14) × (6²) × 6.
= 1/3 (3.14) × 36 × 6.
= 226.08
Thus, the answer is
.
Hope this helps!
