Answer:
x = 99,53633682
Step-by-step explanation:
sin(34) = x/178
x = sin(34)×178
x = 99,53633682
Answer:
Lowest score needed=4.92
Step-by-step explanation:
Using the standard normal distribution table we find the value of standard normal deviate corresponding to area of 15%
For area of 15% we have Z= -1.04
Thus we have
![Z=\frac{X-\overline{X}}{\sigma }\\\\\therefore X=\sigma Z+\overline{X}\\\\](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7BX-%5Coverline%7BX%7D%7D%7B%5Csigma%20%7D%5C%5C%5C%5C%5Ctherefore%20X%3D%5Csigma%20Z%2B%5Coverline%7BX%7D%5C%5C%5C%5C)
Applying values we get
![X=-1.04\times 2+7\\\\X=4.92](https://tex.z-dn.net/?f=X%3D-1.04%5Ctimes%202%2B7%5C%5C%5C%5CX%3D4.92)
Thus lowest score needed = 4.92
0.3 or 30% is the same as 3/10
Answer:
-When (2×-5) intersects at ×-axis the value of × will be zero.
=>F(×)=× 0=2×-5
hence,
0,=2×-5
5=2×
=>×=5/2
