Answer:

40 and 65

Step-by-step explanation:

Craig is 40.

Diane is 65.

40+25=65.

Diane is 25 years older than Craig.

40+20=105

Answer:

Let Craigs age = x

Therefore Dianes age = 25 + x ( since she's 25 years older)

Dianes + Craigs age = (25 + x) + x = 105 (They said both of their ages sums up to 105)

25 + 2x = 105

2x = 80

x = 40

Craigs age is 40 years old.

Dianes age is 65 years old.

Which value of w makes 14=11+w/8 times 6 a true statement?
Vlad [161]

Answer: For the value of w=4, 14=11+\frac{w}{8}\times 6 is a true statement.

Step-by-step explanation:

Since, the given expression,

14=11+\frac{w}{8}\times 6

=  14=11+\frac{6w}{8}

=  14=11+\frac{3w}{4}

= 3=\frac{3w}{4} ( by subtraction property of equality)

⇒ =\frac{w}{4} ( By division property of equality)

⇒ w=4 ( By multiplication property of equality)

Kay [80]

Answer:

The number of people ​surveyed was 330.

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for the population proportion is:

CI=\hat p\pm z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}

The margin of error for this interval is:

MOE= z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}

The information provided is:

\hat p=0.37\\MOE=0.05\\\text{Confidence level}=0.94\\\Rightarrow \alpha=0.06

The critical value of <em>z</em> for 94​% confidence level is, <em>z</em> = 1.88.

*Use a <em>z</em>-table.

Compute the value of <em>n</em> as follows:

MOE= z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}

      n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}

         =[\frac{1.88\times \sqrt{0.37(1-0.37)}}{0.05}]^{2}\\\\=(18.153442)^{2}\\\\=329.5475\\\\\approx 330

Thus, the number of people ​surveyed was 330.
