Answer:

$900

Step-by-step explanation:

Use the formula for simple interest:  i = p r t, where i is the interest earned, p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.

Here, i = $27 = p(0.015)(2), or

               $27 = 0.03p

Dividing both sides by 0.03, we get:

p = $27 / 0.03 = $900

The principal, in this situation, was $900.

In a random sample of 400 residents of Boston, 320 residents indicated that they voted for Obama in the last presidential electi
coldgirl [10]

Answer:

C.I =  0.7608   ≤ p ≤   0.8392

Step-by-step explanation:

Given that:

Let consider a  random sample n = 400 candidates where  320 residents indicated that they voted for Obama

probability \hat p = \dfrac{320}{400}

= 0.8

Level of significance ∝ = 100 -95%

= 5%

= 0.05

The objective is to  develop a 95% confidence interval estimate for the proportion of all Boston residents who voted for Obama.

The confidence internal can be computed as:

=\hat p  \pm Z_{\alpha/2} \sqrt{\dfrac{ p(1-p)}{n } }

where;

Z_{0.05/2} = Z_{0.025} = 1.960

SO;

=0.8  \pm 1.960 \sqrt{\dfrac{ 0.8(1-0.8)}{400 } }

=0.8  \pm 1.960 \sqrt{\dfrac{ 0.8(0.2)}{400 } }

=0.8  \pm 1.960 \sqrt{\dfrac{ 0.16}{400 } }

=0.8  \pm 1.960 \sqrt{4 \times 10^{-4}}

=0.8  \pm 1.960 \times 0.02}

=0.8  \pm 0.0392

= 0.8 - 0.0392     OR   0.8 + 0.0392  

= 0.7608    OR    0.8392

Thus; C.I =  0.7608   ≤ p ≤   0.8392

Write each equation in standard form. identify A,B,C.
aleksley [76]
Write in y=ax²+bx+c form
solve for y

given
\frac{x+5}{3}=-2y+4
solve for y

easy
minus 4 both sides
\frac{x+5}{3}-4=-2y
times -1/2 to both sides
\frac{x+5}{-6}+2=y
y=\frac{x+5}{-6}+2
y=\frac{-x}{6}-\frac{6}{5}+2
2=10/5
y=\frac{-1}{6}x-\frac{6}{5}+\frac{10}{5}
y=\frac{-1}{6}x+\frac{4}{5}
y=ax²+bx+c
y=0x^2+\frac{-1}{6}x+\frac{4}{5}

a=0
b=\frac{-1}{6}
c=\frac{4}{5}
