Harvey is 3 times as old as Jane." 
<span>h = 3j </span>

<span>"The sum of their ages is 48 years." </span>
<span>h + j = 48 </span>

<span>substitution </span>
<span>(3j) + j = 48 </span>
<span>4j = 48 </span>
<span>j = 12 </span>
<span>h = 3j = 36</span>

in the diagram, the length of S is 2/3 the length of T. If S has an area of 368 cm squared, find the perimeter of the figure.
vivado [14]
920 cm squared. Divide S by 2 then multiply to find the value of T. If S = 368 then T = 552, 368 + 552 = 920.

One of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average
Goshia [24]

Answer: 0.0930

Step-by-step explanation:

As per given , we have

H0: μcoffee = 6

Ha: μcoffee < 6

She finds z = −1.68 with one-sided P-value P = 0.0465.

The P-value for two-tailed test is calculated by :

2P(Z>|z|)

For z= -1.68 , we have

2P(Z>|-1.68|)=2P(Z>1.68)

=2(1-P(z\leq1.68))\ \ [\because\ P(Z>z)=1-P(Z\leq z)]

=2(1-0.9535213)\ \ \ [\text{ NORM.S.DIST(z, TRUE}]\\\\=2( 0.0464787)=0.0929573\approx0.0930  

Hence, the correct two-sided P-value for z = −1.68 is 0.0930 .

The area of the face of a cube is 9 square meters. what is the volume of the cuber
Helga [31]

Answer:

<h2>V = 27m³</h2>

Step-by-step explanation:

We know: All faces of a cube are squares.

The formula of an area of a square with a side <em>s</em>:

<em>A = s²</em>

We have <em>A = 9m²</em>

Substitute:

<em>s² = 9 → s = √9 = 3 m</em>.

The formula of a volume of a cube with an edge <em>s</em>:

<em>V = s³</em>

Substitute:

<em>V = 3³ = 27 m³</em>
