Write the equation in exponential form using the two points (0,1) and (1,3)
MakcuM [25]

Answer:

y=3^x

Step-by-step explanation:

The equation of the function in exponential form is

y=a\cdot b^x

The function is determined using points (0,1) and (1,3), so their coordinates satisfy the eduation. Substitute them:

1=a\cdot b^0\Rightarrow a=1\ \ [b^0=1]\\ \\3=a\cdot b^1\Rightarrow 1\cdot b=3,\ b=3

Thus, the equation of the function is

y=3^x

Natalie paid $20.7 for 3 small pizzas and a salad which was $3.
zysi [14]
20.70=3p+3
17.70=3p
$5.90=p
So if you only needed the equation to describe the word problem it is
$20.70=3p+3

If you want to know how much each pizza was it is $5.90; salad $3.00

Use addition properties and strategies to find the sum..1.)34+62+51+46=? 2.)27+68+43=? 3.)42+36+18=? 4.)74+35+16+45=?
erica [24]
1.
34 + 62 = 96 + 51 = 147
147 + 46 = 193

2.
27 + 68 = 95 + 43 = 138
3.
42 + 36 = 78 + 18 = 96
4.
74 + 35 = 109 + 16 = 125 + 45  =
= 70

Step-by-step explanation:

Interpretation of a% confidence interval : A person can be a% confident that the true population parameter lies in it.

Here, A 90% confidence interval to estimate the true proportion of teenagers who drive their own car to school is found to be (0.5907, 0.9093).

i.e. A person can be 90% confident that  the true proportion of teenagers who drive their own car to school lies in (0.5907, 0.9093).

Hence, correct interpretation is : There is a 90% chance that the true proportion of teenagers who drive their own car to school will lie in (0.5907, 0.9093).
