W(x) = 5^2x + 1; Find w(0)

hammer [34]

Answer:

w(0) = 1

Step-by-step explanation:

If w(0) is true, replace all x in the equation with 0 and then solve

w(0) = 5^2(0) + 1

w(0) = 25(0) + 1

w(0) = 0+1

w(0) = 1

Nastasia [14]

Answer:

Sample size is $n=423$

Step-by-step explanation:

Given that,

Margin of error $=4$ %

Confidence level $=90$ %

Suppose, sample proportion $=0.5$

i.e. $\hat{P}=0.5$

We know that,

Margin of error $=2^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }$

∴ $1.64\sqrt{\frac{0.5(0.5)}{n} } \leq 4\%$

$\Rightarrow 1.64\sqrt{\frac{0.25}{n} } \leq 0.04$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq \frac{0.04}{1.64}$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq 0.0243$

$\Rightarrow \sqrt{n}\geq \frac{0.5}{0.0243}$

$\Rightarrow \sqrt{n}\geq 20.57$

squaring on both side,

∴ $n=423.1249$

Hence, the sample size is,

$n=423$

Hence, the correct option is $(b).$

A relation is plotted as a linear function on the coordinate plane starting at point e (0, 27)(0, 27) and ending at point f (5,−

kolbaska11 [484]

The slope of the line is calculated using
y2 - y1 / x2 - x1
Substituting the given values
-8 - 27 / 5 - 0 = -7
The rate of change or the slope is -7
And the initial value is the value of y when x is 0. From the first coordinates, the initial value is 27.
