Answer:
x=2
Step-by-step explanation:
2(x-4)+7=3
2x-8+7=3
2x-1=3
+1 +1
2x=4
/2 /2
x=2
Answer:
P (z) = -1.5094
Step-by-step explanation:
We have to find P-value (that means we have to calculate the test value to evaluate a proportional hypothesis
From problem statement
P₀ = 0,44 44 % from publisher report
The claim :
350 = n random sample
P = 0,40 40 %
To calculate P value
P ( z ) = ( P - P₀ ) / √(P₀*Q₀)/n
then P ( z ) = - 0.04 / √(0,44)(0,56)/350 P(z) = - 0.04/0,02
P (z) = -1.5094
The two integers are 6 and 4 because the factors of 24 are 1,2,3,4,6,8,12,24 and 4 and 6 have the smallest sum out of all of them.
1+24=25
2+12=14
3+8=11
4+6=10
The required salary of Juma in July month is sh.9600.
Given that,
he spent half of his July salary on school fees and two-thirds of the remainder on food.
he spent sh.3200 on food.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
In the question,
Let the slay of Juma in July be x,
Juma spent half of his July salary on school fees = x/2
two-thirds of the remainder on food = 2/3 * x/2 = x/3
he spent sh.3200 on food i.e.
x / 3 = 3200
x = 3200 * 3
x = 9600
Thus, the required salary of Juma in July month is sh.9600.
