I think a=7 the correct answet
erica [24]4 years ago
7 0

Answer:

a = 7

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} = \sqrt{ab}

Given

\sqrt{5}(\sqrt{18} + \sqrt{32})

Distribute parenthesis by \sqrt{5}

= \sqrt{5(18)}  + \sqrt{5(32)}

= \sqrt{90} + \sqrt{160}

= \sqrt{9(10)} + \sqrt{16(10)}

= \sqrt{9} × \sqrt{10} + \sqrt{16} × \sqrt{10}

= 3\sqrt{10} + 4\sqrt{10}

= 7\sqrt{10} ⇒ a = 7

Find the five-number summary for the given data. Min Q1 Q2 Q3 Max
Aleonysh [2.5K]

Answer with Step-by-step explanation:

16 19 21 26 27 29 34 35 35 39 40 41 42 50 50 52 57 60 75 76 78 81 84

the data is already arranged in ascending order

Min=16

Max=84

The quartiles for the odd set of data is given by

Qi=\dfrac{i(n+1)}{4}\ th\ term

where n is the number of elements

Here, n=23

Q1=\dfrac{(23+1)}{4}\ th\ term

Q1=6 th term

Q1=29

Q2=12 th term

Q2=41

Q3=18 th term

Q3=60

Hence, five-number summary for the given data is:

Min  Q1   Q2   Q3   Max

16     29   41     60    84

The value of y varies directly with x2, and y = 150 when x = 5.<br> What is the value of y when x=3?
kow [346]
<span>The value of y when x=3 when the value of y varies directly with x^2, and y = 150 when x = 5 is 54. Since the value of y varies directly with x2, then: y = k * x^2, where k is constant. When y = 150 and x = 5, the value of constant is: 150 = k * 5^2. 150 = k * 25. k = 150/25. k = 6. Thus, when x = 3, the value of y will be: y = 6 * 3^2. y = 6 * 9. y = 54.</span>
